  • Electropolishing

Sulfuric Acid Anodizing(Clear and Color)

The most common and cost-effective anodizing process. Provides excellent abrasion and corrosion resistance. Sulfuric acid Coatings of moderate thickness 1.8 μm to 25 μm are known as Type II. It is also named as MIL-A-8625.Anodizing treatments that provide protection to the surface of the products while allowing the natural beauty to shine through.

Hard Anodizing (Clear and color)

Hardness equal to hard chrome plating is easily attainable. These coatings accept black dyes well, while lighter colours are available on thinner coatings. This is another Anodizing option where Coatings thicker than 25 μm are known as Type III. Type III provides excellent wear resistance and heat dissipation. It is also known as hard coat, hard anodizing, or engineered anodizing available in many standard colour options and an unlimited capability to match or develop new colours.
a. Class I – Without Colour b. Class II – With Colour

Hard Anodizing (Type II):

Type II anodizing is plain coating of titanium. Titanium’s tendency to gall during mechanical sliding or rubbing action (part on part applications) is reduced by this coating due to the added lubricity. In addition, an increase in fatigue strength up to 20% can be achieved and significant improvement in surface finish can be realized without additional mechanical finishing operations. It gives anti-galling anodic coating with proper finish and shine to the product. It is also known with its code AMS2488. Sometimes referred to as gray anodizing, conventional titanium anodizing.

Colour Anodizing

Colour anodizing in titanium involves the same process just the process times and rectifier parameters, and electrolytes are different. Compared to aluminium anodizing there are limited options of colour available in Titanium colour anodizing.


Electropolishing is reverse plating process. In this process, surface particles are pulled off from the surface when DC electricity is applied. Electropolishing, also known as electrochemical polishing, anodic polishing or electrolytic polishing (especially in the metallography field), is an electrochemical process that removes material from a metallic work piece.
