Anodizing Capabilities

Anodizing is an electrochemical process that converts the surface of aluminum into a durable, corrosion-resistant aluminum oxide layer. The aluminum part is immersed in an acid electrolyte bath, and electric current causes oxygen ions to bond with aluminum atoms on the surface, growing an oxide layer that is integral to the base metal (not a coating that can peel). The oxide layer can be dyed in various colors before sealing. There are three main types: Type I (chromic acid — thin, for aerospace), Type II (sulfuric acid — standard, most common), and Type III (hard anodize — thick, for wear resistance). Anodizing is the standard finish for aluminum parts in aerospace, electronics, sporting goods, and architectural applications.

Tolerances:
Type II adds ~0.001" total; Type III adds ~0.002" total (half grows into the surface)
Lead Time:
3-7 business days
Cost Range:
$2-$20 per part; volume pricing significantly lower

Anodizing in Charleston — FAQ

How many Anodizing providers are in Charleston, SC?

The Charleston-North Charleston metropolitan area has approximately 600 manufacturing establishments, many of which offer anodizing services. The area employs about 22,000 manufacturing workers, ensuring a skilled workforce for your project.

What is the difference between Type II and Type III anodizing?

Type II (standard sulfuric acid anodizing) produces a 0.0002"-0.001" thick oxide layer for corrosion protection and aesthetics. Type III (hard anodize) produces a 0.001"-0.004" thick, extremely hard layer (60-70 Rc) for wear resistance and is used on pistons, gears, and sliding components.

What colors can anodized aluminum be?

Type II anodized aluminum can be dyed virtually any color including black, red, blue, green, gold, and purple. Black and gold are the most popular. Clear (natural) anodize preserves the silver aluminum appearance. Color vibrancy depends on the aluminum alloy and anodize thickness.

Does anodizing change dimensions?

Yes, anodizing grows approximately half the oxide thickness into the surface and half outward. Type II adds about 0.0005" per surface. Type III adds about 0.001" per surface. For precision parts, dimension tolerances should account for the anodize buildup.

Is anodizing suitable for outdoor use?

Yes, anodized aluminum is highly weather-resistant. Type II anodized aluminum is standard for architectural applications (window frames, building facades) and can last decades outdoors. Hard anodize (Type III) also provides excellent outdoor durability.
