Specialist ALOCROM 1200 conversion coating services

Alocrom 1200 is a hexavalent conversion coating commonly used across the engineering world, often referred to as Alodine 1200 outside the UK or Chromate. Its purpose is to increase the corrosion protection of Aluminium and Aluminium alloys. 

The process is performed by immersion or swab and can range in colour from a light golden iridescence to brown, depending on immersion time as per specification and application of finished component.
