Advanced Powder Technology (APT)
Astro Alloys offers Praxair APT Powders, which are also known as Advanced Powder Technology. This line of APT carbide powders offer chemical homogeneity, a balance of wear and corrosion, and improved deposit efficiency. APT carbide powders are commonly used as a hard chrome plating alternative for bearings, seals, and paper mill rolls.
