What is Bronze CNC Machining?
Bronze is a durable copper alloy formed by combining copper with tin and lead, offering exceptional machinability with a perfect 100% index. The addition of lead contributes to its superior machinability while maintaining excellent strength, corrosion resistance, and thermal conductivity properties.
Superior Machinability
Bronze achieves a perfect 100% machinability index, making it ideal for complex geometries and tight tolerances in CNC operations.
Marine Applications
Excellent corrosion resistance against seawater makes bronze perfect for marine pumps, fittings, and underwater components.
Low Friction Properties
Ideal for bearings and bushings with continuous frictional contact, providing long-lasting performance in demanding applications.
