Why Choose HAC Coating?

HAC AlCrN stands out for its ability to handle intense heat, abrasion, and mechanical stress—making it one of the most impact-resistant and thermally stable coatings in our lineup. Engineered with a strong aluminum-chromium nitride structure, HAC offers a reliable barrier against wear and thermal breakdown, even in dry or semi-lubricated environments where coolant use is limited or inconsistent.

What sets HAC apart is its toughness under pressure. While other coatings may prioritize lubricity or ultra-high hardness, HAC is built for durability in harsh conditions—especially on abrasive materials like cast iron and high-temp alloys. Its consistent performance in high-speed sawing, hobbing, forging, and forming makes it ideal for industries where downtime is costly and part replacement is disruptive.

If your tools or components face repeated impact, scale formation, or heat-related fatigue, HAC offers a strong, stable solution that holds up where others wear down. It’s a dependable workhorse for manufacturers who need coatings that last under pressure—both thermal and mechanical.

Deposition Process

The HAC coating is applied using advanced Physical Vapor Deposition (PVD) technology. This process involves the deposition of aluminum and chromium in a high-vacuum environment, resulting in a thin, dense, and adherent ceramic layer on the component’s surface. The PVD technique ensures uniform coverage, excellent adhesion, and minimal impact on the component’s dimensional tolerances, making it suitable for precision applications.
