alocrom 1200Alocrom is a Chromate conversion coating chemically applied to aluminium and provides excellent corrosion protection. Alocrom 1200 is also applied before painting or powder coating and used when protection and/or electrical conductivity is required. Alocrom 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 is required, and is suitable for articles which are to be painted or left unpainted.
