Blue Zinc also known as clear passivate or silver zinc.

Traditionally the blue chromates provided up to 48 hours protection to white corrosion in a salt spray cabinet. However we now also offer Hexavalent Free, Trivalent Blues these provide in excess of 120hrs to white corrosion.

As demonstrated in the images above and below zinc plating (especially with clear blue chromates) can vary greatly depending on the base metal quality. Very smooth metals produce a bright finish with rough metals appearing dull.
