Tuyeres
Water-cooled cast copper tuyeres that direct hot blast into the process zone of the blast furnace under intense heat load; available in single-chamber, double-chamber and forged-nose designs.

Bronze Valve and Pump Components
Valve bodies, butterfly valve discs, pump impellers, bushings and similar parts cast in aluminium bronze, tin bronze and gunmetal for corrosive environments.

Marine Bronze Castings
Shipbuilding and ship-repair castings such as propellers, bushings, rudder and shaft parts in seawater-resistant aluminium bronze and manganese bronze alloys.

Art Casting Applications
Art castings in bronze alloys for sculptures, monuments, reliefs and architectural decoration, produced faithfully to the artist’s model.
