C151 Zirconium Copper Alloy Wire

Download PDF

Alloy C151 has excellent solderability, high conductivity, and good strength. C151 has superior softening resistance compared to pure copper C110, which will soften upon heating, limiting the application evironment. Applications can be found in high current interconnects, pin grids, welding wire, or other elevated temperature applications.
