VT machining offers CNC Milling for C101 Copper (UNS C10100 / OFE / Cu-OFE), typically supplied annealed or H02. Oxygen-free electronic copper with ≥101% IACS; for vacuum and hydrogen environments.
CNC Milling Notes for C101 Copper
We use high-efficiency toolpaths with constant engagement on C101 Copper to keep cutting temperature and tool wear under control.
For estimating, a 100 × 100 × 10 mm block of C101 Copper weighs about 0.89 kg.
