Lastifil 508

Hard phosphor bronze refacings

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.

Specifications & Usage


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.
