Copper and Copper Alloys - Newer Materials and Processes

摘要

Copper and copper alloys are versatile in their application and are economical for the manufacture of engineering components. There is a copper alloy for mundane applications like plumbing and also for sophisticated electronics uses and a suitable method for making them. The review highlights some details of newer materials, their applications and innovative processes which enhance strength, quality and saleable yields. New materials include high conductivity Cu-Fe-P-Zr, Copper MMC, Cu-Mg-Fe etc.; spinodal alloys, heat-treated aluminium bronzes, high strength manganese bronzes and lead-free bronzes. The processes discussed include pressure die-casting of copper and brasses, permanent moulding of high conductivity copper, LPDC of brass and aluminium bronze, spray castings, metal foams, turbo-charged high-leaded copper alloys and equa castings. The paper includes mechanical properties, microstructures, photos of typical parts and application details.
