Material Notes:
Alloy C260 is commonly used for electrical components, electronic parts, and mechanical fasteners. The alloy has good strength but poor stress relaxation characteristics and does not make a particularly good spring material. The solderability of the alloy is severely impaired by its high zinc content.Information provided by Eagle Brass Company
