C197 High Performance Alloy Wire
Download PDF
Alloy C197 is a high conductivity copper alloy possessing an excellent combination of strength, conductivity and softening resistance. This alloy can be substituted for medium tempers of brass and bronze when higher electrical conductivity is required or better solderability is needed. Alloy C197 is an improved version of alloy C194 and has substantially greater conductivity at the same strength levels.
