CuNi2SiCr Rod
Nickel-silicon-chromium copper (CuNi2SiCr). Used where high strength and wear resistance are needed: plunger tips for aluminium die-casting machines, resistance welding electrode holders and mould components. It contains no beryllium.

Grade and sizes
CuNi2SiCr
A precipitation-hardening copper alloy with nickel (about 2 %), silicon and chromium. In the hardened condition it reaches a tensile strength of about 650 MPa and a hardness of 190–240 HB; it has high wear resistance and retains its strength at elevated temperatures. Because it contains no beryllium, no beryllium-specific precautions are needed during machining. Its electrical conductivity is about 26 MS/m, lower than that of CuCr1Zr.
Rod standard: EN 12163 (nearest grade CW111C)
- DIAMETER
- Ø10–100 mm
- ORDERING
- Cut to length, minimum 1 kg

Frequently asked questions
What are the designations for CuNi2SiCr?
CuNi2SiCr: EN ≈ CW111C (CuNi2Si), UNS ≈ C18000. Any of these designations can be used in your enquiry; we will match the correct material.
Why can the invoiced weight differ from the calculated weight?
The calculator gives the theoretical weight. The actual weight varies with dimensional tolerances and cutting allowance; we invoice on the actual weight as weighed.
What information should I send for a quote?
We only need the size (diameter × length), quantity and delivery location. If you fill in the calculator above, these details are added to the WhatsApp message automatically.
