Detailed Product Description: | Brass Brass is composed of copper and zinc alloys. If only the copper and zinc on the composition of the brass called ordinary brass. If two or more from a variety of elements called special brass alloy. As the lead, tin, manganese, nickel, iron, silicon, copper alloy composition. Brass has strong wear resistance. Special brass special brass called it high strength, hardness, resistance to chemical corrosion. There is also the mechanical properties of cutting more Prominent. The pull from the brass into a seamless copper tube, soft, strong wear resistance. Seamless brass heat exchangers and condensers can be used for low temperature piping, sea transport pipe. Manufacture of sheet, strip, bars, tubing, casting parts. 62% copper 68%, strong plastic, manufacturing pressure equipment. According to brass alloy elements contained in different types of brass into two ordinary brass and special brass. Brass pressure processing is called deformation brass. Lead Brass Lead brass (commonly known as cutting brass): lead brass actually do not dissolve within the state was free distribution of particles at the grain boundary. Brass lead their organizations α and (α + β) two. α Lead Brass larger because the harmful effects of lead, high temperature plastic is very low, it can only be cold or hot extrusion deformation. (Α + β) lead-brass at high temperatures has good plasticity, can be forged CuCrZr Chromium zirconium copper (CuCrZr) chemical composition (wt)% (Cr :0.25-0 .65, Zr :0.08-0 .20) hardness (HRB78-83) conductivity 43ms / m softening temperature of 550 ℃ characteristics: high strength and hardness , electrical conductivity and thermal conductivity, good wear resistance and reduce wear, hardness after aging treatment, strength, electrical conductivity and thermal conductivity were significantly improved, easy welding. Widely used in motor commutator, spot welding, seam welding machine, welding electrodes, and other high temperature requirements of strength, hardness, conductivity, conductivity pad of parts. Production of EDM electrodes by pitting the ideal to the mirror, while standing performance, to complete the play of pure copper sheet and so difficult to achieve the effect of tungsten steel and other difficult to process materials to perform well. Chromium zirconium copper has good electrical conductivity, thermal conductivity, high hardness, wear antiknock, crack resistance and high softening temperature, less wear and tear during welding electrodes, welding speed, low total cost of welding, welding electrode suitable for welding For pipe, but the general performance of the electroplating workpiece. Application: This product is widely used in automobiles, motorcycles, Barrel (cans) and other machinery manufacturing industry, welding, tip, switch contact, die blocks, a variety of auxiliary devices for welding materials. Specifications: bar, sheet, complete specifications, and according to customer request. Quality requirements: 1. Conductivity eddy current conductivity measuring instrument, measuring three-point averaging ≥ 44MS / M 2. Hardness to Rockwell hardness standards, taking three averaged ≥ 78HRB 3. Softening temperature experiments, temperature 550 ℃ hold for two hours, water quenched after cooling compared with the original hardness of not lower than 15% Physical indicators: hardness:> 75HRB, conductivity:> 75% IACS, softening temperature: 550 ℃ ● Resistance welding electrode: CuCrZr heat and cold through a combination of methods to ensure the performance, it can get the best mechanical and physical properties, it is used To do general-purpose resistance welding electrodes, spot welding or seam welding primarily as a low-carbon steel, coated steel electrodes can also be used as electrodes when welding mild steel Grip, shaft and cushioning material, or as a low-carbon steel welding electrode grip, shaft and lining materials, or as a welder in the large mold, jigs, Stainless steel and heat-resistant steel inlaid with the molds or electrode. ● EDM Electrode: Cr, Cu, thermal conductivity properties, high hardness, wear antiknock used as EDM electrode has good standing, playing sheet does not bend Qu, finish higher merit. ● Mold base material: thermal conductivity properties of chromium copper, hardness, wear anti-knock, the price of copper beryllium mold material is superior than the other characteristics, have begun to die Beryllium copper industry, instead of as a general mold material. Such as shoe soles mold, plumbing, mold, general requirements for smooth high plastic mold, etc. ● connectors, wire, and other high strength wire products. Bronze Beryllium is a beryllium copper alloy (Be0.2 ~ 2.75% wt%), beryllium alloys in all is the one most widely used, the amount of beryllium in the world today has more than 70% of total consumption. Beryllium is a precipitation hardening alloy, after solution and aging treatment of high strength, hardness, elastic limit and fatigue limit, elastic hysteresis is small, and has the corrosion resistance (corrosion resistant bronze alloy in sea water speed: (1.1-1.4) × 10-2mm / year. corrosion depth: (10.9-13.8) × 10-3mm / year.) corrosion, the bronze alloy strength, elongation did not change, it is still in the water can be maintained in more than 40 years, the copper alloy construct submarine cable repeater is irreplaceable body of material. In sulfuric acid medium: bronze in less than 80% concentration of sulfuric acid (room temperature) on the corrosion depth of 0.0012-0.1175mm, concentrations greater than 80% are slightly accelerated the corrosion. , Wear resistance, low temperature, non-magnetic, high electrical conductivity, impact of non-sparking characteristics. Also has good mobility and the ability to reproduce fine patterns. As the many advantages of beryllium copper alloy to make it won in manufacturing a wide range of applications. Copper Copper or copper, also known as copper, with good electrical conductivity and thermal conductivity, excellent plastic and easy hot and cold pressure processing, a large number for the manufacture of wire, cable, brush, copper and other corrosion spark telex requires good electrical conductivity products. That Akagane. Sulphide or oxide copper ore from the smelting of copper obtained can be used to mint coins and artifacts produced. Ming Sung "Heavenly Creations Copper": "Where the use of copper for the world, coming out and baked, only a Akagane. Calamine or Japanese to participate in and lead, turn color to brass; to arsenic and other drugs for the smelting copper-nickel alloy; alum, nitrate and other drugs for the bronze smelting; wide participation and the impact of tin bronze; Japanese diarrhea ﹞ ﹝ lead and write for the bronze. blindly copper is just the beginning of quality. "Guo" History of China, "Part I, section Chapter II: "Their ingredients are pure copper smelting, in addition to the natural trace (0.1-0.2%) of impurities, and no artificial added into the alloy of tin or lead to. less copper, although the hardness, but directly through the beat tools and accessories can be made. " Characteristics: high purity, fine organization, the oxygen content is very low. No holes, trachoma, loose, good conductivity, electrical erosion of high accuracy out of the mold surface, the heat treatment process, the electrode had no direction, suitable for playing fine, fine playing, good thermal channel of processing, scalability , corrosion resistance and weatherability. Uses: Can be used in electrical appliances, construction and chemical industries distillation, in particular electrical terminal printed circuit boards, wires covered with copper, air, bus terminal. Electromagnetic switches, pen holder, housing the root plate. Copper density: 8.96g / (cm) The proportion of copper: 8.89g / (mm) Cu ≥ 99.95% O <003 Conductivity ≥ 57ms / m Hardness ≥ 85.2HV . |
