To anodize, paint, powder coat your aluminum? Specification help .Aluminum oxide is a hard, durable, weather resistant substance that protects the base metal. The coating may be colored by dyeing or may exhibit bronze tones through diffraction phenomena produced by the coating. The coating grows from the base aluminum metal by this electrochemical process. The coating is integral.mill aluminium weathering,Durability of aluminium - Tata Steel ConstructionFeb 19, 2009 . All building materials are eventually degraded by weathering, corrosion, rot and decay. Aluminium's natural ability to resist these influences better than many materials is one of its most widely appreciated features. In its unprotected "mill finish" form aluminium is used very successfully for long-life everyday.

Resistance of Aluminum Alloys To Weathering | CORROSION

The corrosion of aluminum alloys, both wrought and cast, exhibits a “self stopping” characteristic; that is, the rate of attack after an initial exposure period of about one to two years decreases to a very low value, generally to less than 0.2 mil per year. The aluminum alloys displayed high resistance to corrosion and although.

Mill finish - Wikipedia

Mill finish refers to the surface texture (or finish) of metal after it exits a rolling mill, extrusion die, or drawing processes, including sheet, bar, plate, or structural shapes. This texture is usually rough and lacks lustre; it may have spots of oxidation or contamination with mill oil. Most mill finish surfaces are machined or treated.
