Complete Guide to Basic Knowledge of Metallic Materials

Overview: Metal materials are a general term for materials composed primarily of metallic elements or with metallic properties. These include pure metals, alloys, intermetallic compounds, and special metal materials. (Note: Metal oxides (such as aluminum oxide) do not belong to metal materials) 1. Significance: The development of human civilization and social progress are closely related to metal materials. The Bronze Age and Iron Age, which followed the Stone Age, were both significantly marked by the application of metal materials. Today, a wide variety of metal materials have become an important material foundation for the development of human society. 2. Types: Metal materials are generally divided into ferrous metals, non-ferrous metals, and special metal materials. (1) Ferrous metals, also known as steel materials, include industrial pure iron with more than 90% iron content, cast iron with 2% to 4% carbon content, carbon steel with less than 2% carbon content, and various structural steels, stainless steels, heat-resistant steels, high-temperature alloys, stainless steels, precision alloys, etc. In a broad sense, ferrous metals also include chromium, manganese, and their alloys. (2) Non-ferrous metals refer to all metals and their alloys except iron, chromium, and manganese. They are usually divided into light metals, heavy metals, precious metals, semimetals, rare metals, and rare earth metals. The strength and hardness of non-ferrous alloys are generally higher than those of pure metals, and they have higher resistance and a smaller resistance temperature coefficient. (3) Special metal materials include structural metal materials and functional metal materials for different purposes. These include amorphous metal materials obtained through rapid solidification processes, as well as quasicrystals, microcrystalline, nanocrystalline metal materials; also, stealth, hydrogen-resistant, superconducting, shape memory, wear-resistant, vibration damping alloys and metal matrix composites, etc. 3. Properties: Generally divided into process properties and service properties. The so-called process properties refer to the properties exhibited by metal materials under specified cold and hot processing conditions during the manufacturing process of mechanical parts. The good or bad process properties of metal materials determine its ability to be formed during manufacturing. Due to different processing conditions, the required process properties are also different, such as casting performance, weldability, forgeability, heat treatment performance, machinability, etc. The so-called service properties refer to the properties exhibited by metal materials under service conditions, including mechanical properties, physical properties, and chemical properties. The good or bad service properties of metal materials determine its application range and service life. In the mechanical manufacturing industry, general mechanical parts are used at normal temperature, normal pressure, and in non-strongly corrosive media, and each mechanical part will bear different loads during use. The ability of metal materials to resist damage under load is called mechanical properties (formerly also known as mechanical properties). The mechanical properties of metal materials are the main basis for part design and material selection. Different external load properties (such as tensile, compressive, torsional, impact, cyclic loads, etc.) will require different mechanical properties of metal materials. Commonly used mechanical properties include: strength, plasticity, hardness, impact toughness, multiple impact resistance, and fatigue limit, etc.

Create Yuan Futures: Short-term adjustment of Shanghai copper, high probability of upward trend

Shanghai Futures Exchange copper prices rose slightly. The main June contract closed at 43,530 yuan/ton, up 250 yuan, an increase of 0.58%. At 3:00 PM on the same day, the London March copper price was US\$6,042/ton, and the Shanghai-London price ratio was 7.20, lower than 7.21 on the previous trading day, with Shanghai futures copper rising less than the London market. Total contract turnover was 426,998 lots, and open interest increased by 282 lots to 819,646 lots. Main contract turnover was 235,236 lots, and open interest decreased by 3,328 lots to 375,940 lots. The latest price of Shanghai Metals Market No. 1 copper is 42,430-42,550 yuan/ton, with a premium/discount of (discount) 140-(discount) 60. 2. Market Analysis Long-term: Breaking through long-term support, oscillating downward Mid-term: Rebounding from the bottom Short-term: Narrow range fluctuation 3. Market Information On the spot market, today's Shanghai electrolytic copper spot price against the current month contract was quoted at a premium of 60 yuan/ton-100 yuan/ton, the flat copper transaction price was 43,550 yuan/ton-43,610 yuan/ton, and the premium copper transaction price was 43,570 yuan/ton-43,650 yuan/ton. SHFE copper's upward momentum was hindered. Holders hoarded goods in the morning session, waiting for the market to rise. After low-priced goods were released, they were quickly absorbed by speculators. Flat copper was the first to raise the premium to ship goods, and good copper was passively pushed to ship goods. There was still no price difference between brands, but as the price of good copper rose to around 100 yuan, market trading was significantly suppressed, and a stalemate mode was restarted. However, holders began to pay attention to the inter-month price difference before delivery, and speculators increased short-term operations. Downstream buyers purchased on demand, and overall trading remained lukewarm. On the industrial side, according to foreign news on March 2, Chilean Mining Minister Aurora Williams said on Monday that the Chilean government still maintains its 2015 copper production forecast at 6 million tons, which will be a 5% increase from 2014 levels. He said that the decline in international oil prices will help high-cost producers maintain output growth. He also said that the Chilean government will take measures to help small miners cope with high production costs. According to a Lusaka report on February 23, Zambian President Edgar Lungu said on Facebook that if the Lumwana copper mine in the country is idled by Barrick Gold Corporation, the Zambian government may need to consider finding new strategic partners for the mine's other owner, state-owned company ZCCM-IH. According to a Tokyo report on January 20, the Japan Wire and Cable Manufacturers Association reported on Tuesday that Japan's December copper cable shipments (including sales and exports) fell 2.9% year-on-year to 60,000 tons. On the macro side, the People's Bank of China decided to lower the benchmark interest rates for RMB loans and deposits of financial institutions from March 1, 2015. The benchmark interest rate for one-year loans of financial institutions will be lowered by 0.25 percentage points to 5.35%; the benchmark interest rate for one-year deposits will be lowered by 0.25 percentage points to 2.5%. At the same time, in conjunction with the promotion of interest rate market-oriented reforms, the upper limit of the floating range of deposit interest rates of financial institutions will be adjusted from 1.2 times the benchmark deposit interest rate to 1.3 times; other benchmark interest rates for various levels of loans and deposits and personal housing provident fund loan and deposit interest rates will be adjusted accordingly. On Monday, data released by the Institute for Supply Management (ISM) showed that the US ISM manufacturing PMI was 52.9 in February, below the expected 53, falling for the fourth consecutive month and hitting a 13-month low. The expansion pace of US manufacturing in February slowed further compared to January.

Selection of copper-clad steel plating process

The special nature of wire processing requires different copper plating processes than those used for conventional steel parts. Therefore, selecting a suitable copper plating process for wire processing is a crucial issue. The choice of electroplating process usually depends primarily on the requirements for the coating of the product itself. That is, the product is processed first, then electroplated. For example, thickness, brightness, hardness, and dispersion ability. Some also have requirements for current efficiency and deposition rate. Then there is the required pre-plating, intermediate plating, and surface plating. The characteristic of wire electroplating is that the wire processing and electroplating processes are sometimes carried out simultaneously. That is, some are plated after drawing, and some are drawn after plating. Even the electroplating of finished wires is carried out under the traction of the wire-taking machine. The selected process, in addition to the requirements for the coating according to the different Applications of the wire, must also consider the adaptability of the electroplating process to factors such as the wire running speed, the number of traction heads, and the length of the processing line. For CO2 gas-shielded welding wires, due to the strict limitation on the amount of copper attached to the welding wire, for example, the copper content per unit volume should be within 0.52 (mass fraction) of the solder, which is an extremely thin coating, the chemical immersion method, i.e., displacement copper plating, can meet the requirements. However, due to the traditional displacement copper plating method currently used in China, its bonding strength and coating color cannot meet the product requirements. In practice, the process of first immersion plating and then drawing is adopted, so that the copper layer is expanded and thinned during drawing to meet the product requirements. This method often results in coating peeling and base metal exposure. Therefore, selecting a copper plating process with good bonding strength and ductility is crucial for gas-shielded welding wires. Until a new process that enables successful one-time chemical copper plating of finished wires appears, the process of drawing to an intermediate wire diameter, copper plating, and then drawing into a finished product can only be used. Cyanide copper plating or dull acid copper plating should be suitable for this processing process. Due to the high toxicity of cyanide, it is rarely used in the metallurgical wire processing industry. The currently more popular method is still chemical immersion copper plating followed by thickening copper plating and then drawing. The thickening copper plating used is acid copper plating or pyrophosphate copper plating. The chemical method is also mostly used for copper plating in the flat wire processing industry. Traditional displacement copper plating uses a process of copper sulfate plus sulfuric acid. Only a very thin coating can be displaced in a very short time, and the bonding strength is not strong when the copper is thickened on top. If the immersion time is too long in this chemical displacement plating, not only will the coating thickness not increase, but the coating will also become loose and porous, and the iron substrate will also be corroded, greatly reducing the wire strength. The improved method is to add additives with surface retarding effects to the displacement copper plating solution to make the displacement process proceed in an orderly manner. The ideal additive also has a certain brightening effect. For wire products that require a certain thickness or even a thicker coating, the use of displacement plating as a base layer must be very careful. At least until a reliable base plating process suitable for thick copper plating is available, for thick copper plating, the reliable process should still be electrochemical pre-plating. Mature pre-plating processes include cyanide copper nickel plating and high P ratio pyrophosphate copper plating. Weighing the various advantages and disadvantages, nickel plating is better as a pre-plating base in wire drawing electroplating. The thickening copper plating can use acid sulfate copper plating. This is because, after process adjustment, acid copper plating can meet the requirements of high-speed electroplating. The current density can reach 30-50 A/dm2, greatly increasing the deposition rate. In comparison, cyanide copper plating is not suitable due to environmental pollution problems, while pyrophosphate copper plating is not suitable for high-current operation due to its complex composition and high cost. Tests show that in high-speed electroplating in acid copper plating, when the current density increases, the deposition rate of the coating also increases simultaneously, and the approximate relationship is shown in Table 1.
