HARD ANODIZE TYPE III

Thickness from: .0001 to .004 Inch

Color will vary from light tan to black depending on alloy and thickness. Can be dyed in darker colors depending on thickness. Coating Penetrates base metal as much as builds up on the surface. The term thickness includes BOTH the buildup and penetration. Provides very hard ceramic type coating. Abrasion resistance will vary with alloy and thickness. Good dielectric properties. Do not seal coatings where main function is to obtain maximum abrasion or wear resistance. Process can be controlled to be very close thickness tolerances. Where Maximum serviceability or special properties are required, consult metal finisher for best alloy choice. Thick coatings (over .004") will tend to break down sharp edges. Typical applications: hydraulic cylinders wear surfaces, actuating cams, etc. Can be used for electrical insulation coating. "Flash" hard anodize may be used instead of conventional anodize for corrosion resistance and may be more economical in conjunction with other hard anodize areas.


  •  Large tank capacity

SULFURIC ANODIZE

Anodize (Sulfuric) Conventional Types II anodic coatings are intended to improve surface corrosion protection under severe conditions or as a base for paint systems. Coatings can be colored with a large variety of dyes and pigments.


  • Type II    .00007"-.0010" Conventional sulfuric anodizing.
  • Class I     Non-dyed.
  • Class II    Dyed. Specific color on contract
  • Large tank capacity

CHEMICAL FILM

Materials qualified produce coatings that range in color from clear to iridescent yellow or brown. Inspection difficulties may arise with clear coatings because a visual inspection does not reveal the presence of coating.


Class 1A chemical conversion coatings are intended to provide corrosion prevention with left unpainted as well as to improve adhesion of paint finish systems of aluminum and aluminum alloys. May be used on tanks, tubing's and component structures where paint finishes are not required for the exterior surfaces but are required for the interior surfaces.


Class 3 chemical conversion coatings are intended for use as corrosion preventative film for electrical and electronic applications where lower resistant contacts, relative Class 1A coatings and anodic coatings in accordance with MIL-A-8625, are required. The primary difference between a Class 1A and Class 3 coating is thickness.

PRECISION MASKING

For selective finishing. Sometimes, parts require more than one type of finish. Southwest Metal Finishing offers precision masking that seals one area from the other allowing complex, multiple process coatings on the same part. We have the ability to mask large and small areas during anodize to provide conductive surfaces.
