Investment Casting for Marine Propellers, Fittings, and Structural Components
Seawater-Resistant Bronze and Brass Castings for Propulsion, Hull Fittings, and Marine Hardware
Marine parts face the harshest corrosive environment in industry. Investment casting ? also known as lost wax casting ? is how propellers, hull fittings, and deck hardware achieve the precision seawater demands.
Pahwa MetalTech produces marine propellers ? including advanced toroidal designs ? alongside hull fittings, shaft components, and structural marine hardware for commercial and specialist maritime applications.
Nickel aluminium bronze, manganese bronze, and naval brass are our primary marine alloys ? chosen for exceptional seawater corrosion resistance, biofouling resistance, and strength for propulsion load demands.

Rudder hardware and tiller fittings
Seaworthy From the First Pour ? Marine Castings Built to Outlast the Ocean
Marine applications demand alloy selection, not just material grade. Pahwa MetalTech works with naval architects and marine engineers to specify the right bronze or brass for your exact service conditions.
Send us your propeller design, fitting drawings, or vessel specification. We'll assess hydrodynamic geometry, alloy requirements, and tolerances ? and return a quote suitable for classification if required.
