VT machining offers CNC Punching 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 Punching Notes for C101 Copper
C101 Copper punches cleanly with standard clearance; minimum hole diameter is about the sheet thickness.
For estimating, a 100 × 100 × 10 mm block of C101 Copper weighs about 0.89 kg.

Request a QuoteFrequently Asked Questions
Can VT machining make custom C101 Copper parts to my drawing?
Yes. C101 Copper punching 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.
What tolerances can you hold for CNC Punching C101 Copper?
Achievable tolerances for C101 Copper punching depend on the alloy, geometry and feature size. Punching holds hole-position repeatability to around ±0.10 mm. Exact figures are confirmed against your drawing callouts.
What is the typical lead time and minimum order for CNC Punching C101 Copper?
CNC Punching prototypes for C101 Copper can be produced quickly and scaled to series production. Send your drawing and quantity and we will advise lead time and any minimum order.
How clean are the edges produced by CNC Punching on C101 Copper?
Punched C101 Copper edges are clean when punch/die clearance is correct; we set clearance to the gauge and can add deburring if specified.
Does CNC Punching C101 Copper require dedicated tooling?
Punching uses programmable turret tooling; standard tools cover most patterns, with special tools added for unique forms.
What surface finish is achievable on C101 Copper with CNC Punching?
Surface finish on C101 Copper is controlled to your specification; we confirm the achievable Ra against your callout.
