C194 class conductivity! It is a high-strength, high-conductivity copper alloy that has also achieved high strength.
"NPZ" is a copper alloy that achieves high electrical conductivity by adding Ni and P to copper and subjecting it to heat treatment, resulting in the precipitation of intermetallic compounds made of Ni and P. Furthermore, through a unique processing heat treatment method, it has also achieved high strength that was not previously attainable in this system. Additionally, the addition of Zn prevents the heating detachment of solder and Sn plating films. 【Features】 ○ Excellent electrical conductivity comparable to C194 class ○ Mechanical strength, including tensile strength, yield strength, and Hv hardness, is on par with proven copper alloys from other companies ○ Good stress relaxation characteristics and bendability have been achieved ○ Alloy design aimed at cost reduction For more details, please contact us or download the catalog.
