For hard soldering of steel, malleable cast iron, copper, copper alloys, nickel and nickel alloys. These solder joints are applicable at working temperatures up to +200°C. It is also suitable in the field of low temperature. There is no notably determined reduction of tensile strength and notch impact strength of solder joints on copper, brass and steel at – 196°C. You can solder blank material in connection with a flux according to DIN EN 1045 – FH 10 ( "CuFe Nr. 1" paste or "CuFe P" powder, respectively). According to DVGW, working sheet GW 2 also approved for the hard soldering of copper pipes in the field of cold and warm water installations. These solders are applied, among others, in medical as well as in the food industry. Also perfectly suited for pipes where technical gas is transported, e.g. oxygen, nitrogen, hydrogen, CO2 as well as noble gas (i.e. Argon and Helium).
