View ProductsAluminum is widely used in the manufacture of commercial and industrial parts. The benefits of using this light metal include its high strength, non-toxicity, and ease of forming into everything from extrusions to custom spun parts. Aluminum is also more cost-effective than stainless steel.
While aluminum is naturally corrosion resistant, that resistance has limitations. Over time, aluminum will pit and corrode for a variety of reasons.
Untreated aluminum tends to corrode when exposed to alkaline or acidic environments.
Galvanic corrosion occurs when bare aluminum comes in contact with metals like copper, zinc, and certain types of steel. And while aluminum doesn&#;t &#;rust&#; in a way that causes structural risk, the surface of aluminum does oxidize and tarnish in unsightly ways, degrading the appearance of product quality.
Ways of preventing aluminum corrosion include painting and anodizing. When used to coat aluminum, painting tends to chip and flake over time. Anodizing is an electrochemical treatment that boosts aluminum&#;s natural surface oxide layer. This latter method is good, but remains vulnerable to acidic environments and cannot be made in a uniform appearance or a variety of colors.
Powder coating provides a range of benefits when coating aluminum parts, extrusions, and castings.
What should you look for in an aluminum powder coating partner?
Experience in surface preparation and pre-treatment is critical. Impurities, grease, and oils from the manufacturing process must be cleaned away. Any surface oxide needs to be removed and the surface roughened to improve powder adhesion.

The right pre-treatment for your parts depends on their condition as they arrive for powder coating, and an experienced eye is needed to assure that cleaning and pre-treatment are sufficient to assure proper power adhesion and coating life.
Another consideration is powder coating thickness. For aluminum, powder coating is best applied in layers of between 2mm and 4mm. Thicker layers risk &#;orange peel&#; and pockmark effects.
