Description

CuNi30Mn1Fe (CW354H) is comparable to CuNi30Mn1Fe, mat. no. 2.0882, acc. to DIN 17664 : 1983-12. To the comparable DIN-mark applies: The material shows favorable specific strength values also at endurance loading and increased temperatures. Thermal conductivity of pure copper is strongly reduced by Ni, the electrical resistance strongly increases according to the Ni-content. Fe-addition increases the corrosion resistance. CuNi30Mn1Fe is resistant to water and seawater, coolant and solvent, alkaline substances, alkaline saline solutions and non-oxidizing acids. warm forming: good cold forming: good machinability: moderately hard soldering: very good soft soldering: very good gas-shielded welding: very good burnishing: good Application: For seawater pipilines, tubes and plates for all types of tubular heat-exchanger (condenser, cooler, seawater evaporators, high pressure feeder water heater) on ships, in power plants, in petroleum processing an in chemical factories as well as in saltern plants. The material is established for condenser in ammoniac steam.
