 Shenzhen River Xing Copper and Aluminum Co., Ltd. is China's set of professional, advanced, high quality in one H68 brass plate manufacturer of H68 yellow copper supplier, H68 brass plate agents, 

 H68 brass plate distributor of H68 brass plate distributor of its professional production, supply, agents, distributors, distribution brass GB Jiangxi Copper, Luoyang Copper, Yunnan Copper imports 

 Japan's Mitsubishi, Japan Sambo, Japanese cherry, Sa, Germany, the United States Fen cola. H68 brass plate is our company's flagship production, sales, agents, distribution, distribution of products. 

 I supply the brass plate of H68 (standard yellow copper C2668) copper purity ≥ 68%. With good thermoelectric conductivity, processability, ductility, corrosion resistance and weather resistance. Can be applied to India 

 Brush bus, circuit boards, covered with the Copperbelt, terminals, electrical, distillation, construction and chemical industry. Yet still quality products, complete specifications, everything you buy peace of mind, must be assured. The copper density 8.89, melting point 1083oC, its main drawback is that strength and lower hardness can not be used as structural components. In the industrial main purpose is the manufacture of electrical industrial conductors and conductive parts, and in the preparation of various alloys. With good thermoelectric conductivity, processability, ductility, corrosion resistance and weather resistance. Can be applied to the printing bus, circuit boards, covered with copper tape, terminals, electrical, distillation, construction and chemical industry. Yet still quality products, complete specifications, everything you buy peace of mind, must be assured. 
 The following is an overview of our company produces H68 brass plate, the characteristics and scope of application, chemical composition, mechanical properties, heat treatment specification is as follows: 

 An overview of the general H68 brass plate: 
 If it is composed of a variety of alloy by more than two kinds of elements called special brass. Such as lead, tin, manganese, nickel, iron, silicon, copper alloy. Brass have a strong wear resistance. Special 

 Special brass known as special brass, high strength, hardness, chemical resistance. There is the cutting of the mechanical properties are more prominent. Pull into a seamless copper from brass, soft, 

 Wear resistance strong. Brass seamless pipe heat exchanger and condenser can be used for low temperature piping, submarine transport tube. Manufacture of sheet metal, Rod, bar, pipe, cast parts. Copper in 

 62% to 68%, plastic, manufacturing pressure equipment. According to the different types of alloying elements contained in the brass, brass divided into ordinary brass and special brass two. Pressure processing 

 Brass called the deformation of brass. Add elements copper zinc alloy, brass, a beautiful yellow, collectively referred to as brass. Binary alloy of copper and zinc that ordinary brass, or a simple yellow 

 Copper. Three yuan more than the brass called special brass or complex brass. Lower than 36% zinc brass alloy by solid solution, with good cold working properties, such as zinc 30% of the brass is often 

 Used to make casings, commonly known as the cartridge case brass, or 73 brass. Zinc brass alloy by solid solution between 36 to 42 percent, one of the most commonly used is zinc 40% of the Tiananmen brass. For 

 To improve the performance of ordinary brass, and often add other elements such as aluminum, nickel, manganese, tin, silicon, lead. Aluminum can improve the strength, hardness and corrosion resistance of brass, but the plasticity decreases fitness 

 Cooperation seagoing vessel condenser and other corrosion-resistant parts. Tin can improve the strength of brass and corrosion resistance to seawater, it said, the Navy brass, as the ship of thermal equipment and propeller. Lead can be improved 
 Brass cutting; this cutting brass is commonly used for watch parts. Brass castings used to make valves and pipe fittings. 

 Features and Scope of the general brass plate: 
 ① a very good plasticity (in brass) and high strength, good cutting performance, easy to weld, general corrosion stability, but it is easy to produce corrosion cracking. As an ordinary 

 Brass in one of the most widely used varieties. 
 ② strength than copper (but not in the ordinary brass, which is the lowest), electrical conductivity, thermal conductivity, corrosion resistance, high in the atmosphere and freshwater and have a good plasticity, easy-cold, hot 

 Power processing, ease of welding, forging and tin, no stress corrosion cracking tendency.
