Classification of copper alloys of copper alloy classification in three ways: 

 ① Press the alloy into 
 Classified by alloy can be divided into non-alloy copper and copper alloys. Non-high-copper alloys, including copper, ductile copper, deoxidized copper, oxygen-free copper, etc., habits, people will be called non-copper or copper alloy of copper, but also called copper, copper alloys and other copper alloy belongs. China and Russia to alloy copper into brass, bronze and copper-nickel alloy, and then divided into smaller categories in the alloy. 

 ② by function 
 By function, there are electrical and thermal conductivity copper alloy (as long as non-alloy of copper and copper alloy micro-) structure with a copper alloy (including almost all the copper alloy), corrosion of copper alloys (mainly tin brass, aluminum, brass , a variety of non-copper-nickel alloy, aluminum bronze, titanium, bronze, etc.) wear-resistant copper alloy (mainly lead, tin, aluminum, manganese and other elements of complex brass, aluminum bronze, etc.), cutting copper alloy (copper - lead, copper - tellurium, copper - antimony alloy), flexible copper alloys (mainly antimony bronze, aluminum bronze, beryllium bronze, titanium, bronze, etc.) damping copper alloy (high-manganese-copper alloy, etc.), art copper alloy (copper, simple single-copper, bronze, aluminum bronze, copper-nickel alloy, etc.). Clearly, many copper alloys have to have more features. 

 ③ divided according to material forming method 
 Divided according to material forming method for casting copper alloy and copper alloy deformation. In fact, many cast copper alloys can be used for both, and can be used for deformation processing. Usually deformed copper alloys can be used for casting, and many can not be cast copper alloy forging, extrusion, deep drawing and drawing and other deformation processing. Cast copper alloy and copper alloy deformation can be subdivided into casting copper, brass, bronze and copper-nickel alloy. 


 Straight-line sale of brass rods brass sheet brass with brass hexagonal copper specifications, lead cast copper rod, copper side of the specification, angular size of copper, copper flat bar specifications, providing material evidence SGS report, are welcome to come call to discuss. Conductivity, thermal conductivity, and fresh water in the atmosphere have a higher corrosion resistance and good plasticity, easy-to-cold, hot pressure processing, easy welding, forging and tin, no tendency to stress corrosion cracking
