VT machining offers CNC Honing for C122 Copper (UNS C12200 / DHP / Cu-DHP), typically supplied annealed or H55. Phosphorus-deoxidised; brazes and welds well but lower conductivity (~85% IACS).
CNC Honing Notes for C122 Copper
Honing gives C122 Copper bores precise size, roundness and a controlled cross-hatch; for soft grades we use fine silicon-carbide stones.

What is CNC Honing C122 Copper and how is it done?
CNC Honing C122 Copper refers to honing finishes bores with abrasive stones to precise size, roundness and a cross-hatch surface. Applied to C122 Copper — excellent electrical and thermal conductivity — VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
What tolerances can you hold for CNC Honing C122 Copper?
Achievable tolerances for C122 Copper finishing depend on the alloy, geometry and feature size. We hold tight, repeatable tolerances appropriate to the feature and material. Exact figures are confirmed against your drawing callouts.
Does CNC Honing C122 Copper require dedicated tooling?
Most C122 Copper finishing work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
What is the typical lead time and minimum order for CNC Honing C122 Copper?
CNC Honing prototypes for C122 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.
Why is C122 Copper a good choice for CNC Honing?
C122 Copper is excellent electrical and thermal conductivity, which makes it well suited to CNC Honing. We tune the process to the alloy so the finished C122 Copper finishing part meets your dimensional and functional requirements.
Can VT machining make custom C122 Copper parts to my drawing?
Yes. C122 Copper finishing 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.
