Copper base alloy adapted to be formed as a semi-solid metal slurry

摘要

A precipitation hardenable copper base alloy adapted for forming in the semi-solid slurry condition consists essentially of from about 5 to about 8% by weight nickel, from about 5 to about 7.5% by weight aluminum, from about 0.5 to about 1.25% by weight silicon and the balance essentially copper. The alloy has a microstructure comprising discrete particles contained in a lower melting point matrix. The alloy is particularly suited for forging into components such as cartridge cases.
