Even when the heat is unbearable:
Top conductivity and stability.

CuCr1Zr is a precipitation-hardening, low-alloy copper which is distinguished by high strength values, even at increased temperatures, with very good resistance to temper embrittlement as well as high softening temperatures. While its good cold-workability remains restricted to the solution annealed state, CuCr1Zr is generally good for hot-working. In its hardened state, it has a high thermal and electrical conductivity as well as a high temperature resistance.

CuCr1Zr is resistant to industrial atmospheres, waste and drinking water (flow rates <1.5 m/s) and pure water vapour, non-oxidising acids and neutral salt solutions. When annealing in an atmosphere containing hydrogen, no damage to the materials occurs (hydrogen embrittlement).

KME Mansfeld’s CuCr1Zr product portfolio includes plates, sheets, bars and profiles.

Typical areas of use

CuCr1Zr is used mainly for:

  • Electrical engineering
  • Plant construction
  • Busbars
  • As a material for mould plates


All KME products come in specially made, standard-compliant, secure packaging. This guarantees retention of shape, ensuring that a product’s properties are preserved to the utmost after leaving the factory. Sea freight packaging is something else we offer as standard. We can assess individual packaging requirements, provided they can be presented technically, and offer them for an extra charge.
