Bronze Investment Casting

Bronze investment casting uses wax patterns and ceramic shells to produce complex parts from copper alloys. BRK Metal casts bronze parts to customer drawings, drawing on casting experience since 2002.

What Is Bronze?

Bronze is the general name for copper alloys made mainly with tin or aluminum. It is harder than pure copper and resists wear better.

Common Bronze Types

• Tin bronze: Used for sliding and wear parts such as bushings and bearings.
• Aluminum bronze: Known for high strength and resistance to seawater corrosion.
• Red bronze: Common in valves, fittings and pump parts.

We select the alloy according to the service environment and the standard on your drawing.

Benefits of Bronze Castings

• Wear resistance and low friction
• Corrosion resistance in seawater and many other media
• Alloy options for applications where sparking is a concern
• Good thermal and electrical conductivity

Why Investment Casting for Bronze?

Copper alloys are expensive, so machining chips add real cost. Investment casting produces parts close to final size, which reduces that waste. Internal passages and thin sections can also be cast as one piece.

Applications

Bronze investment castings serve the pump and valve, marine, machinery and electrical sectors, especially where small, detailed parts suit investment casting better than sand casting.
