Surface Finishing

Anodizing Services

Electrochemical conversion coating that creates a durable, corrosion-resistant oxide layer on aluminum — available in decorative Type II and wear-resistant Type III hard coat finishes.

Process Overview

Type II — Decorative

Clear, black, and custom colors. 5–25μm coating thickness. Ideal for enclosures, consumer products, and automotive trim.

Type III — Hard Coat

25–150μm thick coating with surface hardness up to 60 HRC. For high-wear mechanical and industrial parts.

Color & Masking

Dyeing after anodizing for vibrant UV-stable colors. Selective masking for threads, bores, and mating surfaces.

Frequently Asked Questions

Type II vs Type III anodizing — which do I need?

Type II for appearance and moderate corrosion protection. Type III when wear resistance and hardness are critical — e.g. sliding surfaces and high-wear mechanical parts.

Will anodizing affect dimensions?

Yes — approximately 50% of coating thickness builds outward. Specify anodizing in your drawing and we account for growth in pre-machining dimensions.

Can you anodize threads?

Threads are typically masked before anodizing to preserve fit. Specify thread class and we coordinate masking accordingly.
