Chromic Acid Anodising

Chromic acid anodising is a specialist surface finish used primarily within the defence and aerospace sectors and industries where subsequent painting/adhesive bonding is required or in applications where crack detection is sought. Chromic acid anodising is the preferred process for the treatment of castings and other components where the minimisation of the loss of fatigue strength resulting from the anodising process is desirable.

Restrictions

Painting - Adhesive Bonding


For customers that require components painted, or used in composite structures, we offer an overnight service with guaranteed availability at an agreed time the next morning, allowing you time to transport your items for finishing or manufacture before the anodised coating cures, usually within 8-16 hours.
