Precision CNC Machining for Copper T2 – High‑Conductivity Custom Parts
Copper T2 CNC machining (C11000 / electrolytic tough pitch copper) offers the highest electrical conductivity (101% IACS) and excellent thermal conductivity among common copper alloys. It is ideal for busbars, terminals, heat sinks, and high‑current electrical components. At Ranglink, we specialize in custom copper parts – from prototypes to production runs.

Key Properties of Copper T2 (C11000)
| Property | Value / Rating |
|---|---|
| Purity (Cu + Ag) | ≥99.9% |
| Electrical conductivity | 101% IACS (~58 MS/m) |
| Thermal conductivity | ~391 W/(m·K) |
| Tensile strength (annealed) | ~220 MPa |
| Yield strength (annealed) | ~70 MPa |
| Hardness (Brinell, annealed) | ~45 |
| Density | 8.94 g/cm³ |
| Corrosion resistance | Good (atmospheric & water) |
| Machinability rating | Fair (20% of free‑cutting brass) – use sharp tools & coolant |
💡 Machining tip: Copper T2 is gummy and prone to built‑up edges. Use sharp carbide tools, high coolant pressure, and proper chip evacuation to achieve excellent surface finish.
