Description

CuAl8Fe3 (CW303G) 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. CuAl10Fe3Mn2 has a high strength at high temperatures up to approx. 300°C and a high endurance strength also at corrosion strain. The alloy is scaling resistant , shows a high wear resistance and a high corrosion resistance to saltwater, sulfite bases and mineral acids, it shows no erosion and cavitation sensitivity. Processing properties: warm forming: good cold forming: moderately machinability: good soft soldering: moderately hard soldering: moderately gas-shielded welding: good burnishing: good CuAl10Fe3Mn2 is used for plates for condenser and heat-transfer bottoms, for sheets in chemical apparatus engineering.
