For specialist applications where both high corrosion protection and areas of electrical conductivity are required on the same component we offer a dual finishing service (also known as selective anodising). The service is available for a combination of alocrom, sulphuric acid anodising and hard anodising coatings. Selective treatment of different areas of a component is achieved by a masking process which is typically applied to specific holes or earthing points.
Due to the entirely manual nature of the masking process and the need to treat components in several finishing lines, lead times for dual finished products are typically 5 to 7 working days but may be longer for larger batches. Please contact us to discuss lead times for individual jobs.
