| CW308G (DIN EN 12163 : 2011-08) | CW308G | DIN EN 12163 : 2011-08 | DIN EN 12163 : 2011-08 replaced by DIN EN 12163 : 2016-11 | Replaced | Germany | CuAl11Fe6Ni6 | CuAl11Fe6Ni6 | CuAl11Fe6Ni6 (CW308G) 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 has a particularly high strength as well as high corrosion and wear 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 The material is used for construction parts of higher strength, higher loaded bearing parts, pivot bearings at impact loading as well as for valves, valve seats, cover plates, link blocks, wear parts, die plates for chipless forming and for hot steam instruments. |
