Ask Dongguan where to sell copper bars, brass rod, copper rod, beryllium copper rod, bronze bar

Answer:

In addition, lead, antimony, bismuth and other impurities will make the crystal copper not together, causing hot shortness, will also affect the processing of copper. The pure copper with high purity is usually refined by electrolysis: the pure copper (i.e., the coarse copper) is used as the anode, the pure copper as the cathode, and the LS copper solution as the electrolyte. As the current passes through, the Impure Copper on the anode is gradually dissolved, and the copper is gradually deposited on the cathode. Such refined copper; purity up to 99.99%. Copper is a relatively pure copper, generally can be considered to be pure copper, conductive and plastic are better, but the strength and hardness of some less.

Copper containing 62% to 68%, strong plasticity, the manufacture of pressure equipment. The use of copper is much more extensive than that of pure iron, and 50% of copper is purified into pure copper every year for use in the electrical industry. The red copper here must be very pure, with more than 99.95% copper. A very small amount of impurities, especially phosphorus, arsenic, aluminum, will greatly reduce the conductivity of copper. Oxygen containing copper (copper is easily mixed with a small amount of oxygen) has great influence on the conductivity of copper, used in the electrical industry generally must be copper.

Copper is characterized by its softness, ease of processing, good electrical conductivity, good heat transfer, and corrosion resistance. It has been used since ancient times for metals in a wide variety of fields, such as money, wires and building materials. Adding a few percent of beryllium to copper gives it a good quality, while it has a high strength that is comparable to that of a special steel and has a good elasticity. It is the best material in copper alloys. Extension material sheet and strip bars, mainly in the shape of supply, because both beryllium copper with high strength and high conductivity, fatigue resistance, high thermal conductivity, workability, corrosion resistance, so as elastic material is widely used. In order to apply for various purposes, we have prepared various types and different hardness of beryllium copper alloy QBe2, QBe1.7, can provide the thinnest thickness of 0.045mm material. The copper (phosphor bronze) (bronze) 0.03~0.35% degassing agent P content by adding phosphorus bronze, tin content of 5~8%. and other trace elements such as iron Fe, which extend zinc Zn, fatigue resistance are good for electrical and mechanical materials, reliability is higher than the general copper alloy products.

Copper is an alloy of tin phosphor bronze, with good conductive properties, not easy to heat, to ensure the safety and has strong anti fatigue. The alloy has excellent machinability and chip properties, and can rapidly shorten the processing time of parts. Brass is an alloy of copper and zinc. If it is only made of copper and zinc, it is called ordinary brass. If it is made up of more than two elements, a variety of alloys are called special brass. A copper alloy consisting of lead, tin, manganese, nickel, lead, iron, and silicon. Brass has stronger abrasion resistance. Special brass, also called special brass, is of high strength, hardness and chemical resistance. Also, the mechanical properties of the cutting process are more prominent. A seamless copper tube drawn from brass. It is soft and has a strong abrasion resistance. The brass seamless tube can be used in heat exchangers and condensers, cryogenic pipes and submarine pipelines. Manufacturing of sheet, strip, bar, tube, casting parts, etc..
