What is Zirconium Copper C15000?

UNS C15000 is a precipitation-hardened copper alloy strengthened through controlled heat treatment. Unlike pure copper, it retains excellent electrical conductivity while offering significantly higher mechanical strength and softening resistance.

At DOMADIA™, this alloy is supplied in:

  • Forgings
  • Rods
  • Bars

These shapes ensure compatibility with resistance spot welding and seam welding applications.

Chemical Composition of Zirconium Copper C15000

The performance of Zirconium Copper C15000 comes from its refined chemical balance:

  • Copper (Cu): Balance (~99%)
  • Zirconium (Zr): 0.10% – 0.20%

Even this small addition of zirconium transforms standard copper into a high-performance alloy, enhancing:

  • Grain refinement
  • Heat resistance
  • Mechanical strength
  • Wear resistance

The result? A copper alloy that performs under repeated thermal cycling.
