Overview
What is Aluminium Hard Anodising?
Hard anodising (Type III) produces an exceptionally thick, dense oxide layer that transforms aluminium into a surface almost as hard as tool steel. This process is specifically designed for components that face extreme mechanical wear, high temperatures and aggressive chemical environments. If your parts need to survive heavy-duty industrial use without failure, hard anodising is the answer.
