Sulphuric anodising services use an electrolytic process to produce a wear- and corrosion-resistant oxide layer, united with the substrate.

​

• Uniform coating distribution that is aesthetically pleasing and, when sealed, the surface finish is easy to maintain

• 5 – 25 microns thickness

• Black Dye, Red, Blue, Gold, Green, "we will also consider and support other colours please enquire"

• Fully RoHS-compliant process​

​​

Hard Anodising Similar to sulphuric anodising, but processed at a lower concentration of sulphuric acid, and at a lower temperature, producing a far thicker and harder surface suited for marine environments and engineering purposes. 

​

• 25 – 80 microns thickness

• Black Dye available

• Fully RoHS-compliant process​

​​

Zinc Nickel Plating, The process the deposition of zinc onto a ferrous metal substrate by electrolysis, generating a corrosion-resisting, sacrificial corrosive protection which can give several hundred hours of salt spray protection depending on the Passivate abd Top Coat. 

​

•  5 – 25 microns thickness

• Clear and colour passivate available

• Fully RoHS-compliant process​

• Chrome Free Conversion

​​

Chrome-free conversion coating that can be used as a final finish, with corrosion resisting properties that match its hexavalent equivalents on many alloys, or act as a base for paint, powder coat, lacquers, or bonding. 

​

Iridite NCP Chrome Free conversion coating that can be used as a final finish, with corrosion resisting properties that match its hexavalent equivalents on many alloys or act as a base for paint, powder coat, lacquers, or bonding

​

• ​Surtec 650 + 650V 

• Fully RoHS, ELV, and WEEE-compliant process

Chromate conversion coatings on aluminum are also known as yellow Bonderite, Iridite, and Alodine, or Chem Film. They are used for everyday aluminum components, hardware, automotive wheels, heat sinks and aerospace applications (aircraft hulls, side and torsion struts, shock absorbers, flight control systems, and landing gear). Chromate conversion coating is applied by dipping, spraying, or brushing, and the coating thickness doesn’t change the dimensions of the coated part. If applied to a surface before the primer, it can improve the adhesion of both primer and paint.

​

Aluminum chromate conversion coatings, often referred to as chemical film or under the trade names Alodine or Irridite, produce a thin coating in the range of 0.00001-0.00004 inches in thickness.  Aluminum chromate conversion coatings are amorphous in structure with a gel-like composition hydrated with water.  This characteristic provides aluminum chromate conversion coatings with a unique self-healing characteristic if scratched or abraded.  Metal exposed from a scratch slowly becomes covered by soluble chromate from areas adjacent to the scratch.
