About Bronze FAQs
Machining bronze is generally easy, but it requires attention to avoid work-hardening. Bronze alloys produce smooth finishes and are suitable for CNC processes.
Brass is easier to machine than bronze due to its softness, while bronze alloys tend to be harder, offering better wear and corrosion resistance.
Yes, coolant helps reduce heat, prevent work-hardening, and improve surface finish and tool life when machining bronze.
Common grades for CNC machining include:
- Phosphor bronze (for electrical connectors, springs).
- Aluminum bronze (for marine and industrial applications).
- Tin bronze (for bearings, gears, valves).
CNC machining bronze offers good machinability, wear resistance, and durability in harsh environments. However, it can work-harden, leading to faster tool wear, and it tends to be more expensive compared to materials like brass or aluminum.
