Chemical Conversion
exceptional resistance
Chemical conversion coatings are produced on Aluminium by chemical methods. The coatings are usually applied by immersion, spray or swabbing.
The appearance of the film can vary from a silver colour to dark yellow depending on the solution composition. Chromate films are thin and not very abrasion resistant but do give exceptional corrosion resistance with low electrical resistance.
Paint and organic finishes adhere well to the chromate film and it is often used as a base coat.
The most common type of conversion coatings in use today are Alocrom and Surtec. This is available as Alocrom 1200s (golden film) and Surtec 650.
