QuLPA-NiGuss Powder – Laser Cladding Powder Nickel Base – Cast Iron & Bronze, 32 HRC
QuLPA-NiGuss Powder – Laser Cladding Powder Nickel Base – Cast Iron & Bronze, 32 HRC
QuLPA-NiGuss is the nickel-base cladding powder for castings — designed for the two material groups that are hardest to repair with matching filler metals: cast iron and bronze alloys.
Nickel is the key here: the weld metal stays tough and crack-resistant instead of hardening the way a matching cast-iron filler would. At 32 HRC the deposit sits deliberately in the middle range — hard enough for functional surfaces, soft enough to be machined afterwards. Particle size 45–150 µm for classic nozzle-based LMD.
Base materials
- Cast iron
- Bronze alloys
Applications
- Cladding and repair of cast components
- Restoration of bronze bearing surfaces, bushings and sliding elements
- Rebuilding worn functional surfaces to size
- Coating of cast housings and pump parts
Advantages
- 32 HRC — machinable deposit, no post-hardening required
- Nickel base: tough, crack-resistant weld metal on brittle castings
- Covers cast iron and bronze with a single powder
- Particle size 45–150 µm — standard fraction for nozzle-based LMD
Powder form: grain size 45 - 150 µm — for laser metal deposition (LMD).
