🔹 These are the go-to hard films for high-temperature applications (up to 800–900°C). The aluminum content forms a protective oxide layer at heat. Perfect for dry machining and superalloys.
🔹 Harder and tougher than TiN (up to ~3500 HV), with a darker, charcoal-gray appearance. Ideal for high-speed machining and stamping tools. hard film names
🔹 Pale gold, biocompatible, and corrosion-resistant. Often used in decorative hardware, biomedical implants, and soldering tips. 🔹 These are the go-to hard films for
