DURACON® 45M
The recently developed Iron-Cobalt-Nickel alloy DURACON® 45M combines high hardness and high tensile strength with an excellent thermal conductivity. This unique combination of properties makes the material attractive for the production of moulds and dies. The very high thermal conductivity allows a significant reduction of the cycle time and enhances the surface quality and the dimensional accuracy of the produced plastic parts. Furthermore, DURACON® 45M has a thermal expansion coefficient close to that of typical tool steels, which reduces thermal stress in composite moulds. Additionally, DURACON® 45M is free of Beryllium.

Properties of DURACON® 45M in comparison
| Alloy | Thermal conductivity | Tensile strength | Density |
|---|---|---|---|
| [Wm-1 K-1] | [MPa] | [kg m-3] | |
| 1.23443 / 1.2083 | 11 – 35 | 1990 | 7850 |
| CuBe2 | ca. 100 | 670 – 1150 | 8090 – 8620 |

All data for DURACON® 45M for the age hardened condition. As a rule DURACON® 45M is delivered in the base condition (martensitic). The base condition allows the mechanical workability by e. g. turning or milling. After age hardening at 500 °C (2 hours) post-processing by grinding is possible.
