CuCrZr-PowerFil® was developed specifically to meet the requirements of AS22759, AS29606, NEMA WC 67, ASTM B 624, and MIL-DTL-25038, as environmentally friendly substitute for CuCdCr and CuCd0.1, which Lamifil will no longer produce. PowerFil® delivers a minimum strength of 414 MPa in combination of 7% elongation with a electrical conductivity of 90% IACS minimum, excellent flex life and thermal resistance. The CuCr1Zr has a higher tensile strength and is used for welding wire and 3D laser printing. The maximum oxygen content is 5 ppm.
