VT machining offers CNC Turning 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 Turning Notes for C101 Copper
On the lathe C101 Copper needs chip-breaker inserts and constant chip load to avoid long, stringy swarf.
For estimating, a 100 × 100 × 10 mm block of C101 Copper weighs about 0.89 kg.

Which industries use CNC Turning C101 Copper parts?
CNC Turning C101 Copper parts are used across aerospace, medical, automotive, electronics, semiconductor and general industrial sectors — anywhere precise C101 Copper components are required.
How clean are the edges produced by CNC Turning on C101 Copper?
Machined C101 Copper edges are clean and to specification; edge-break or deburring is added when your drawing calls for it.
What surface finish is achievable on C101 Copper with CNC Turning?
Surface finish on C101 Copper is controlled to your specification; we confirm the achievable Ra against your callout.
What tolerances can you hold for CNC Turning C101 Copper?
Achievable tolerances for C101 Copper turning depend on the alloy, geometry and feature size. Turning holds diameter tolerances to around ±0.005 mm with concentricity within 0.01 mm. Exact figures are confirmed against your drawing callouts.
What material thickness or size range suits CNC Turning C101 Copper?
Turned C101 Copper parts are produced from bar or chuck stock across a wide diameter range.
Why is C101 Copper a good choice for CNC Turning?
C101 Copper is excellent electrical and thermal conductivity, which makes it well suited to CNC Turning. We tune the process to the alloy so the finished C101 Copper turning part meets your dimensional and functional requirements.
