Copper Alloy (UNS C18030)

Topics Covered

Chemical Composition


Beryllium copper series are alloys of the metal copper. They are known for their high strength coupled with non-magnetic and non-sparking features. Beryllium copper alloys are ductile, weldable, and machinable. They are resistant to non-oxidizing acids. Beryllium copper is produced in many forms such as square, round, flat and shaped, on spools, in coils, and in straight lengths.

UNS C18030 is a type of beryllium copper alloy. The following datasheet discusses the chemical composition and properties of copper UNS C18030.
