EN 12167 Grade CuAl10Fe3Mn2 R550

CuAl10Fe3Mn2 (CW306G) 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. Processing properties: warm forming: good cold forming: unfavorable machinability: moderately soft soldering: unfavorable hard soldering: moderately gas-shielded welding: good burnishing: good CuAl10Fe3Mn2 is a construction material for chemical apparatus engineering. It is particularly suitable for impact, dynamic or wear loaded components in engine and transmission engineering, for scaling resistant parts, for bolts, high-strength screws and nuts, for shafts, spindles, worm and gear wheels and rims as well as for control system parts in hydraulics, for bearings and sliding elements.
