Sulphuric Anodising

Our anodising line has been set up for sulphuric anodising and surface treatments such as chromium(VI)-free trivalent passivation of aluminium.

Sulphuric Anodising is the most common form of anodising and is used in many industries ranging from catering and lighting to medical etc. The anodised film can range in thicknesses from 1 – 45 micron depending on the grade of aluminium and specific customer requirements.

At Rictor we offer Type II (Decorative) and Type III (Hard) anodising in a variety of finishes: Matt, Satin and Bright. Please use the contact form on this page to make an enquiry.

Why choose sulphuric anodising?

• Excellent corrosion resistance
• Available in a variety of colours
• Scratch resistant
• Cost effective
• 1 to 45μm coating thickness

Standard clear sulphuric anodising reflects the natural colour of the metal but the appearance can be varied by pre-treating the aluminium with processes such as bead blasting and other pre-treatments and or by varying the etching process.

Careful selection of the pre-treatment process can give the part a matt, satin, or bright finish with high corrosion resistance and a decorative appearance. It is the most versatile of all anodising processes due to its high corrosion resistance and decorative appearance. Finishes can be applied to sulphuric anodised parts which can be supplied in Matt, Satin or Bright finishes.

Bead Blasting

At Rictor Engineering we also provide bead blasting; a process whereby beads are blasted at a surface to improve the general surface finish of a part.

It can be used to reduce the level of machining marks in a component but also to refine the surface so that a more regular and even finish is achieved. This technique can also be used to restore aged or tarnished components, revealing a clean surface finish.
