Chemical Processing

Chemical Processing is the process of changing the surface of an object for the purpose of improving its appearance and/or durability.

Metal finishing can be used to improve the following qualities of the metal:

• Appearance
• Adhesion (wettability)
• Solderability
• Corrosion resistance
• Tarnish resistance
• Chemical resistance
• Hardness
• Modify electrical conductivity
• Remove surface flaws
• Control surface friction
• Remove ferrous contaminants

At Arrow Cryogenics, all our chemical processing services are performed entirely in-house.

We offer a variety of chemical processing services for your part and component needs, some of which include:

• Aluminum Anodizing
• Hard Coat Aluminum Anodizing
• Electropolishing
• Passivations
• Cerakote
• Trivalent Chromate
• Dry Film Lube – DFL
