Passivation

Anodizing is primarily used for aluminum alloys (6061, 7075, 2024). Titanium alloys can also be anodized. Other metals such as steel and brass require different surface treatments like electroplating or passivation.

Yes, powder coating and liquid spray paint can match RAL, Pantone color cards, or customer-provided samples. Anodizing provides over 50 standard colors, with custom color matching available upon request.

Yes, most surface treatments increase the part's surface thickness. Anodization typically adds 0.5-2 mils per side, while electroplating adds 0.1-2 mils depending on the type. Our engineers account for this material allowance during machining to ensure the final dimensions meet specifications.

Type II is standard anodizing with a thinner oxide layer (0.5-1.5 mil), suitable for decoration and corrosion resistance. Type III (hard) anodizing features a thicker oxide layer (1-2 mil) with significantly higher hardness and wear resistance, ideal for functional applications.

Standard machined surface roughness is 125 Ra (3.2 µm); finish machining achieves 63 Ra (1.6 µm). Post-processing such as sandblasting or polishing can further improve surface quality.

In CNC turning, the workpiece rotates while the tool remains stationary, suitable for cylindrical parts such as shafts, pins, and sleeves. In CNC machining, the workpiece is stationary while the tool rotates, ideal for flat, prismatic and complex 3D geometric shapes.
