  • Weld-solder filler
    Publication number: 20060018784
    Abstract: Conventional weld fillers contain copper, aluminum and manganese. These weld fillers are as a rule not suited for the welding of thin or rust-free sheet metals. The inventive weld filler contains 0.5 to 6.0 percent by weight Al, 0.5 to 8.0 percent by weight Mn, the usual impurities are less than or equal to 1.0 percent by weight and as the remainder Cu. This weld filler is better suited for the welding of thin or rust-free sheet metals than the up to now known weld fillers.
