Solid welding wire in a special Sn-bronze quality, suitable for refacings on steel, cast iron and copper alloys.
Can also be used for repairing casting defects in Sn-bronze and for joining Sn-bronze and brass workpieces.
Also suitable for joining galvanized plate without burning the Zn layer.
High hardness and better abrasion resistance than 6% Sn bronze.
Porous free deposit.
Repair of castings in bronze, bearing seatings, refacing and joining steel and cast iron.
Welding CuSn8 (2.1030) - CuSn6 (2.1020) - G-CuSn7ZnPb (2.1090), G-CuSn10 (2.1050) aso.
Hardness: 80 HB
Clean and degrease the workpieces.
Phosphorbronze with thickness > 6 mm (0,24"): preheating 150-200 °C (300-390 °F).
Keep molten pool and welding time as short as possible.
To avoid shrinking stresses and to refine the grains, the welding joint can be hot peened.
