Q: What is hard coat anodizing?
A: Hard coat anodizing is an electro-chemical process of converting aluminum to aluminum oxide. Hard coat anodizing makes it possible to produce thick wear and corrosion resistance coating on a variety of aluminum alloys. The hard coat process also allows this light metal to be used in many design applications normally restricted to steel. Hard coating is being used in architectural anodizing where its natural color and wear resistance are assets.
Q: Can aluminum anodized parts be Teflon( PTFE) coated?
A: Yes. For a better co-efficient of friction and further corrosion resistance, anodized aluminum parts are often PTFE coated.
Q: What is Iridite?
A: It is a primer for paint.
Q: Does Aluminum metal corrode?
A: Yes, aluminum can corrode. However, when corrosion on aluminum in the form of uniform oxide film occurs, this film protects the rest of the metal from further corrosion. Anodizing of aluminum is that protective coating.
Q: What is Type ll (Sulfuric Acid) or Color Anodizing?
A: It is a thin transparent anodic coating (.0001-.0004), which provides corrosion resistance to aluminum alloys and is excellent for dying to achieve highly cosmetic and decorative finishes.
Q: What is Type lll ( Hard Coat Anodizing), and what are its benefits?
A: Hard coat anodizing is a thicker anodic coating (.001-.003), which gives additional hardness, abrasion resistance and corrosion resistance to aluminum. This coating is not transparent, produces its own color as a result of the particular alloy being used and only lends itself to good dye absorption in black.
Q: Can aluminum parts be PTFE coated?
A: Yes. PTFE impregnation on Hard Coat Anodizing greatly increases wear resistance, corrosion resistance and the general lifespan of any aluminum part.
Q: What is chem-film per Mil-C-5541?
A: A Chem film is a water dilute solution that coats a hexavalent chromium gel on the aluminum surface to form a surface corrosion resistant film when dried and improves paint adhesion.
Q: How is Mil-DTL-5541F different?
A: This finish is used as an alternative to the Mil-C-5541 chromate conversion coating to comply with the new European RoHS Directive for greater restrictions of certain hazardous substances in electronics and electrical equipment.
