Guide:There are many copper materials.,Sino-foreign standard。We generally be mainly said to be domestic standards。Copper materials have domestic standards Industry Standard、Distinguishment of local standards and corporate standards。National standards in copper material standards have recommended standards and mandatory standards。Most companies use copper materials China standards。Of course, some companies have developed Higher standards than national standards,Enterprise standard。The standard of copper material enterprise is of course the standard for enterprises.。Various manufacturers can formulate copper enterprise standards。There are many systems of copper grades.。Including the United States、 nation、U.K、France and Russia, etc.。

Copper grade type?

1、Copper grade:Color is purple pure copper material。Copper materials also include pure copper、Oxygen-free、Phosphate and special copper materials。

(9 16 brass tube near 08221)2、Brass:Copper zinc alloy material。

3、Bronze:Original copper tin alloy material,Later, the brass﹑Copper alloy material other than white copper。

4、White copper material:Adding elements as nickel、Silver white、Copper-based alloy material with metallic gloss。

American copper material grade representation method?

AmericaUNSNumber system(ASTME527)Regulation,Copper and copper alloy are used5Bit number as a code,Expressed as “C+xxxxx(Five digits)”,in,Processing copper“Cl0000?C15999”,Processing copper alloy is“C16000?C79999”。This code system is in the past3 Based on the number of digits,Developed by the American Materials and Test Association and the US Motor Engineers Association,And become the US metal and alloy unified number code system(UNS)Composition part。
