Tensile and wear resistant, high resistance to water, corrosion, friction. Great savings are made by applying to steel - cut and abrasion resistant coating. Use: For welding and surfacing brass, tin bronzes, copper and copper bronzes, steel, steel-lithium and cast iron, for joining steel with bronze, with copper and with copper bronzes, for surfacing shafts, pumps, ship parts, gears, cracks, housings, sliding surfaces, forming tools, pistons, pump wheels, blades, turbines, copper spoons, etc. For materials: 2.1010, 2.1020, 2.1030. For wall thicknesses above 4 mm, a preheating temperature of 250-400°C is recommended.
