EN 12451 Grade CuAl5As O60: High-Strength, Corrosion-Resistant Wrought Alloy
CuAl5As (CW300G) 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. The alloy is corrosion resistant to saltwater, potash salt solutions and mineral acids and particularly resistant to hot saline solutions. Processing properties: warm forming: unfavorable cold forming: good machinability: moderately soft soldering: unfavorable hard soldering: unfavorable gas-shielded welding: moderately burnishing: moderately The material is used for tubes, heat transformers and condensers in potash plants and in salines, in mining and in chemical industry.
