Lastifil 64

Seawater resistant bronze wire

Ni alloyed aluminium bronze wire with a very high resistance against corrosion and erosion by seawater.

Refacing of propellers of aluminium bronze (with Ni and/or Mn) without danger for desaluminification in warm seawater.

Refacing and joining copper alloys, steel and cast iron (metal to metal wear).

Applicable to working temperatures up to 250°C (480°F).


Specifications & Usage


Refacing shippropellers, pumphousings, augers, shafts in pumps and machinery, valves, driving wheels and gliding contacts in different industries.

Repair of casting flaws in (nickel) aluminium bronze pieces.

Joining of plates and pipes in chemical and food-industry.

Joining bronze to steel.

Welding of bronze with Wn° 2.0916, 2.0920, 2.0928, 2.0932, 2.0936, 2.0940, 2.0960, 2.0962, 2.0966, 2.0970, 2.0978, 2.0980.

Hardness: 140 - 190 HB

Electrical resistivity: 0.2 ohm.mm²/m (1.10-5 ohm/in/in2)


Helium generates a hotter pool what makes it easier to reface large bronze pieces or steel without porosity.

To join bronze to steel: "butter" the steel with Lastifil 64 (on an amperage as low as possible or with a pulsed arc, and make than the joint with the bronze piece (preheat 150 to 200 °C (300 - 390 °F)).
