CuAl9Ni3Fe2 (CW304G) is a wrought alloy of high strength, also at increased temperatures. The strength properties of cold formable wrought alloys are primarily dependent on the deformation grade. Tensile strength, yield strength and hardness rise according to the increasing cold forming grade. Elongation after fracture and contraction at fracture are decreasing. Thermal conductivity is reduced by the Al-content, electrical conductivity decreases according to the increasing AL-content. CuAl9Ni3Fe2 has a high strength at high temperatures up to approx. 300°C and a high endurance strength also at corrosion strain. The alloy has a low friction coefficient, is scaling resistant , shows a high wear resistance, high strength also at impact loading and a high corrosion resistance to saltwater, sulfite bases and mineral acids. Processing properties: warm forming: good cold forming: unfavorable machinability: moderately soft soldering: unfavorable hard soldering: moderately gas-shielded welding: very good burnishing: good The material is due to its favorable weldability particularly suitable for mixed constructions of congenerous cast and wrought material. Application for bearing parts for impact loading as well as for parts in animal food industry.
