|---|---|---|---|---|
| CuBe2 CW101C | 2.1247 | 2,0 | 0,4 | balance |
Material Properties
- Precipitation hardened alloy with good thermal conductivity and high hardness.
- Not suitable for case hardening or nitriding.
Applications
- Plastic blow and injection moulds
- Inserts in steel tools on spots requiring higher cooling rates. Due to a high tensile strength also suitable for inserts with a high ratio of length/cross section
- Nozzles and needles for hot runner systems
- Cooling inserts in moulds and ingot moulds
