VT machining offers CNC Milling for C630 Aluminum Bronze (UNS C63000 / CuAl10Ni5Fe4), typically supplied as extruded / annealed. Nickel-aluminium bronze: higher strength and seawater resistance than C623.
CNC Milling Notes for C630 Aluminum Bronze
We use high-efficiency toolpaths with constant engagement on C630 Aluminum Bronze to keep cutting temperature and tool wear under control.
For estimating, a 100 × 100 × 10 mm block of C630 Aluminum Bronze weighs about 0.76 kg.

What is the typical lead time and minimum order for CNC Milling C630 Aluminum Bronze?
CNC Milling prototypes for C630 Aluminum Bronze can be produced quickly and scaled to series production. Send your drawing and quantity and we will advise lead time and any minimum order.
Can VT machining make custom C630 Aluminum Bronze parts to my drawing?
Yes. C630 Aluminum Bronze machining is made to order from your CAD/2D drawing. Share your geometry, material grade, tolerance and quantity and we will confirm feasibility, lead time and pricing.
Why is C630 Aluminum Bronze a good choice for CNC Milling?
C630 Aluminum Bronze is high-strength and seawater-corrosion-resistant, which makes it well suited to CNC Milling. We tune the process to the alloy so the finished C630 Aluminum Bronze machining part meets your dimensional and functional requirements.
What tolerances can you hold for CNC Milling C630 Aluminum Bronze?
Achievable tolerances for C630 Aluminum Bronze machining depend on the alloy, geometry and feature size. Milling holds positional and dimensional tolerances to around ±0.01 mm, tighter with precision setups. Exact figures are confirmed against your drawing callouts.
