Introduction
Copper casting alloys are produced using the casting process wherein a liquid material is poured into a mold containing a hollow cavity of a desired shape. Then the liquid is allowed to solidify. The solidified part is later removed and this is known as a casting. The casting process is considered by many to be more versatile as it has fewer limitations on shape.
The following datasheet discusses the chemical composition and properties of UNS C90710 copper casting alloy.
