Description

CuAl10Ni5Fe4 (CW307G) 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. CuAl10Ni5Fe4 has a high strength at high temperatures up to approx. 300°C and a high endurance strength also at corrosion strain. The alloy is particularly resistant to cavitation , 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: very good burnishing: good The material is used for plates for condenser and heat transfer bottoms, for shafts, screws, wear parts as well as for controlling parts for hydraulic appliances, hot steam instruments, high voltage switchers, suction rolls in paper industry, cylinder corebushings for combustion engines, mechanically and chemically loaded parts in machine and shipbuilding and mining.,Copper alloy rod for general purposes.
