CNC Bronze Alloys
CNC Bronze Alloys are a class of alloy materials containing copper base, usually composed of copper (Cu) with elements such as tin (Sn), aluminum (Al), phosphorus (P), silicon (Si) or manganese (Mn). These alloys have good mechanical properties, wear resistance, corrosion resistance and excellent machinability, and are widely used in industrial manufacturing.

Why Bronze Alloys Make Sense for CNC Machining
Excellent wear resistance
Bronze alloys offer low friction and strong wear resistance, making them ideal for bushings, bearings, gears, and sliding components.
Good corrosion resistance
Bronze performs well in seawater, humid environments, and outdoor applications, especially compared with many plain steels.
High strength and toughness
Many bronze grades provide good mechanical strength and impact resistance for heavy-duty mechanical parts.
Good machinability
Bronze alloys are suitable for CNC machining of precision parts that require stable dimensions and smooth bearing surfaces.

Finishes That Make Sense For Bronze Alloys
Polishing
Smooths and brightens bronze surfaces to improve appearance and reduce surface roughness.
Nickel Plating
Applies a protective nickel layer to improve corrosion resistance, wear resistance, and surface hardness.
Patina Finish
Creates a controlled aged or decorative surface color while helping protect the bronze surface.
Bead Blasting
Creates a consistent matte surface texture and helps hide minor machining lines on bronze parts.
