hard anodising – the leading specialist

We are the country’s leading Hard Anodising specialists (aluminium anodisers) – our clients are generally leading businesses in Aerospace, Defence and Automotive sectors. Hard anodising produces a relatively dense, thick oxide layer. As a result, the film will tend to be darker in appearance although the final colour is largely dependent on the alloying constituents (elements) of the base material and, in its natural state, can be anything from light green/gold to dark grey/charcoal.

The use of Hard anodising has become very important where weight saving (e.g. by the use of Aluminium instead of Steel) combined with good corrosion protection and wear resistance are required. Also unsealed anodic coatings can absorb and retain oil when used on sliding surfaces for cylinders and pistons etc, providing longer lasting lubrication.
