Pull bar commonly if the incorporation of zinc and lead, without affecting the quality (i.e., not brittle, does not affect the finish) the case can also add what material? What will be added to reflect, how much is the general amount?
There are three classifications of copper alloys:According to the alloy systemDivided by the alloy system can be divided into non alloy of copper and copper alloy. Copper alloy including Gao Chuntong, ductile copper, copper, copper deoxidation, habits, people will be called non alloy copper copper or copper, also called copper, and copper alloy to copper alloys. China and Russia put together gold copper brass, bronze and copper into, and then dividing small alloy in a large class.Division by functionAccording to the function division, a copper alloy for thermal conductivity (as long as there are non alloyed copper and micro alloyed copper and copper alloy) structure (including nearly all copper alloy), corrosion resistance of copper alloy (including tin brass, aluminum brass, cupronickel, various aluminum bronze, Titanium Bronze wear-resistant copper alloy (mainly) lead, tin, aluminum and manganese complex brass, aluminum bronze), free cutting copper alloy (copper - lead, copper, copper alloy - antimony tellurium), elastic copper alloy (mainly antimony bronze, aluminum bronze, beryllium bronze, Titanium Bronze etc.) and high damping copper alloy (manganese bronze gold, copper (copper alloy) art, simple single copper, tin bronze, aluminum bronze, copper and copper alloy). Obviously, many have multiple functions.Classification according to the method of material formationAccording to the material forming method can be divided into cast copper alloy and copper alloy deformation. In fact, many copper alloy can be used for casting, but also can be used for deformation processing. Usually deformed copper alloy can be used for casting, casting and many copper alloy but not by forging, extrusion, deep drawing and drawing of copper alloy and processing. The deformation of casting copper alloy can be subdivided into casting copper, brass, bronze and copper.
