VT machining offers CNC Milling for C260 Brass (UNS C26000 / CuZn30 / Cartridge brass), typically supplied annealed or half-hard. Excellent cold-forming brass; not leaded, so chips are stringy compared with C360.
CNC Milling Notes for C260 Brass
We use high-efficiency toolpaths with constant engagement on C260 Brass to keep cutting temperature and tool wear under control.
For estimating, a 100 × 100 × 10 mm block of C260 Brass weighs about 0.85 kg.
