VT machining offers CNC Drilling for C145 Tellurium Copper (UNS C14500 / CuTeP), typically supplied H02 half-hard. Tellurium makes copper free-machining while keeping ~93% IACS conductivity.
CNC Drilling Notes for C145 Tellurium Copper
C145 Tellurium Copper drills cleanly; we choose point angle and peck depth by hole depth-to-diameter ratio and hold position to the drawing.
For estimating, a 100 × 100 × 10 mm block of C145 Tellurium Copper weighs about 0.89 kg.
