Alocrom is a Chromate conversion coating chemically applied to aluminium, which provides corrosion protection. It is also applied prior to painting or powder coating and is used when protection and/or electrical conductivity is required.

It is suitable for all types of aluminium alloy (N.B. Should not come into contact with foodstuffs) including castings and high silicon alloys which can be problematical to anodise.

Good electrical conductivity, corrosion resistance and good paint key are all benefits gained by Chromate Conversion.

Chromate conversion coatings currently carried out by us.

Alocrom 1000

Alocrom 1000 produces protective coatings on aluminium and its alloys without significantly changing the appearance of the aluminium surface. Alocrom 1000 is approved to MIL-C-5541 (Class 3) and is recommended where a very low surface electrical resistance is required. 

Alocrom 1200

Alocrom 1200 is ideal for coating all types of aluminium and aluminium alloys including high silicon pressure die-castings. It should be used on aluminium wherever maximum corrosion resistance and when electrical conductivity is required. It is suitable for components that are to be painted or left unpainted. It gives a protective golden coloured coating which is, like anodising, integral with the aluminium.

Light to medium Alocrom coatings have minimal effect on surface electrical resistance.

Alocrom 1200 is approved to DEF-STAN 03-18 and to MIL-C-5541C and MIL-C-81706. 

This process is also known as Alchromate, Bonderite 710 & Alodine 1200 .
