Semi-Hard Anodising

The semi-hard anodising process was devised to satisfy the requirements for a hard surface finish combined with good colour options. Semi-hard anodising provides increased hardness, good adhesion, electrical insulation, heat resistance and increased corrosion resistance. Semi-hard anodising will usually result in a slightly lower surface finish to that of the original component but can be more easily dyed than the full hard anodised finish, giving a greater range of available colours.
