Brass hard solder


Hard solder with excellent strength for soldering of steel and galvanised steel plates, copper, nickel and casting material as well as autogenous addition for welding of brass and bronze. Our brass hard solder distinguishes itself in very good flow properties. The tendency to corrosion is strongly reduced due to Mn -, Si - and Sn - contents. Furthermore, crack formation will be prevented. On galvanised steel plates the zinc flows back to the soldering seam after removing the flame. Thus an optimal corrosion protection is guaranteed in the thermal scope.
