copper zirconium alloy powder, Zr-Cu
Zirconium copper alloy
Zirconium - copper alloy is the best choice material for circuit contact because of its
good conductivity and thermal conductivity. If the switch contact disconnects the circuit,
the resulting arc puts a considerable load on the material, which is what high-temperature
chromium does. Chromium can improve the arc ablative resistance of the material, and
has good fusion resistance, and can prevent the bonding of the soft copper during
fusion welding. Chromium also has a high oxygen philicity, can absorb the oxygen
released during the breaking process.
Zirconium copper alloy is not only used for small signal transistor or power transistor
discrete packaging, but also for IC with excellent performance, for various types of lead
frame, high-power switches, relays and other electronic components. CuZr alloy has
high heat resistance and softening resistance by adding Zr to high purity copper without
oxygen. Therefore, it has attracted much attention as a non-electroplated lead frame
material by taking advantage of the superior performance of copper without oxygen.
