Anodized Aluminium Components Export from India

Anodizing is an electrochemical process that converts the surface of aluminium into a hard, durable aluminium oxide layer. Unlike paint or plating, the anodic layer is integral to the base material — it cannot peel, chip or flake. This makes it the preferred surface treatment for aerospace structures, defence components, automotive trim and consumer electronics.

Type II conventional anodizing produces a porous 5-25 um coating suitable for decorative and mild corrosion protection applications. Type III hardcoat anodizing produces a dense 25-75 um coating with hardness equivalent to 60-70 HRC — used for wear surfaces, sliding components, hydraulic cylinder bores and bearing housings in harsh environments.

Not all aluminium alloys anodize identically. High-copper alloys (2000 series) and high-zinc alloys (7000 series) require modified bath chemistry and tighter process control to achieve uniform colour and coating thickness. Our NADCAP-capable partners have developed alloy-specific anodizing processes for 2024-T3, 7075-T6 and other aerospace alloys commonly specified in defence and aviation programmes.

For components requiring precise masking — threaded holes, bearing bores, mating surfaces and electrical contact areas — we provide precision masked anodizing using custom tooling. This ensures dimensional integrity of critical features while protecting the bulk surface.
