C21000 is the most common corrosion resistant copper alloy
. C21000 has excellent corrosion resistance, good deep tensile properties, ductility, moderate electrical conductivity, and good strength. Typical uses of the C21000 include ammunition assemblies, coins, commemorative medallions, and a wide variety of other applications. C21000 is a copper-zinc alloy that is stronger and more durable than copper alloy. C21000 is an excellent corrosion-resistant, ductile, highly conductive metal used in industrial and electrical industries.
