| 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.

Coating
Thickness
Typical surface thicknesses of 20-30µm are achievable
through the semi-hard anodising process.
Sealing
The following sealing options are available for semi-hard
anodised components:
Colour
Dyes
Colour options are available with semi-hard anodising for
an additional charge. We use the selected colours below from
the Clariant dye range although other colours are available
for large orders:
Please
note that these colours are meant as a guide and no guarantee
can be made for a match between this online colour swab and
the final colour. Also, due to the varying nature of alloys
and dyes, we cannot guarantee colour consistency between orders
over time or even across large batches.
