Hard anodizing creates a durable oxide layer on aluminum components, improving surface hardness, corrosion resistance, wear performance, and electrical insulation. It is commonly considered for fixtures, equipment plates, handling components, and high-contact mechanical surfaces.

Passivation removes surface contaminants and strengthens the natural protective layer of stainless steel. It is commonly used for precision hardware, shafts, fittings, brackets, chamber-related components, and cleanable equipment parts.

Bead blasting produces a uniform matte appearance and reduces visible machining marks. It is often applied before anodizing or other treatments to improve surface consistency on aluminum and stainless-steel components.

Polishing reduces surface irregularities and improves smoothness, appearance, and cleanability. It can be applied to contact surfaces, chamber-related parts, fixtures, covers, and components requiring controlled surface conditions.
