Key benefits include: Extreme hardness & wear resistance — significantly harder than typical anodizing and often compared to hardened steels in surface properties. Thick protective oxide layer that resists scratching, abrasion and corrosion. Better surface durability under stress — ideal for high-use parts. Good chemical resistance and improved ability to retain lubricantsThis coating is a mil-spec (military grade) finish for aluminum parts that see high load and heat like engines.
