Soft Anodizing
Conventional anodizing for corrosion resistance and appearance.
Soft Anodizing
Soft anodizing (MIL-PRF-8625 Type II) forms a thin, uniform porous coating and closes the pores by sealing to provide corrosion resistance and appearance. Coating thickness is controlled to the drawing value within 5–30 µm, the 336-hour salt spray requirement is met, and black dyeing is available. It suits parts where dimensional stability of assembly and sealing faces and a clean surface matter, such as hydrogen tank, HVAC and motor parts.
