Metalworking<\/strong><\/h1>\n

In metalworking, joining different metals through soft soldering, brazing, and welding is an integral part of the manufacturing process. The soft soldering process, with soldering temperatures up to a maximum of 450 \u00b0C, is well-suited\u2014with the appropriate selection of flux\u2014for copper, copper alloys, aluminum, and both alloyed and unalloyed steel grades. For joints with higher requirements for strength or temperature resistance, brazing with copper and silver brazes at temperatures between 650 \u00b0C and 800 \u00b0C, or brass brazes at a processing temperature of around 900 \u00b0C, is suitable. For brazing aluminum, soft brazing alloys with brazing temperatures ranging from approximately 280 \u00b0C to 430 \u00b0C are primarily used. This requires the use of special aluminum fluxes and aluminum soft brazing pastes. <\/p>\n\t\t Discover Products<\/a>\n\t\t<\/div>\n\t\t\t<\/div><\/div>\n<\/section>\n\n\n
