CEWELD NiCrBSi 4 Tig (Colmonoy 4) offers outstanding metallurgical and physical properties making them ideally suited to solving wear mechanisms such as abrasion, erosion, corrosion and high-temperatures encountered in service.
CEWELD NiCrBSi 4 Tig (Colmonoy 4) is a nickel-base alloy containing chromium boride. It is recommended for hard surfacing parts to resist wear, heat, corrosion and galling. Deposits, which have only moderate hardness (Rockwell C 35-45), can be machined with carbide tooling. Is highly resistant to semi-molten glass. It is normally used in the as-cast condition.

CEWELD NiCrBSi 4 Tig (Colmonoy 4) offers superior wear protection, retaining its hardness up to 300ºC (600ºF) with significant resistance to oxidation. A good combination of impact resistance and wear resistance.It is resistant to atmospheric, salt water, and salt spray corrosion, and has excellent oxidation resistance up to its melting range. It retains satisfactory performance in many organic acids, but high corrosion rates are observed in hot, strong inorganic acids.
