Titanium-based coatings such as TiN, TiCN, TiAlN, AlTiN, and CrAlN play a critical role in improving the performance and lifespan of cold heading dies and punches.
According to industry data, these coatings offer exceptional hardness (up to 4200 HV), good friction coefficients, and high temperature resistance (up to 1200°C), making them ideal for high-speed forming and precision tooling applications.
For example, TiN coating provides excellent wear resistance and a distinctive gold finish, while CrAlN coating delivers superior oxidation resistance and is suitable for high-temperature environments up to 1000°C, these are the usual options for most of our punches.
If you are looking for high-performance coated punches or dies, understanding these coating differences is essential for optimizing your cold forming process.
