Hard chrome on aluminum IDs

++++

We need a plating vendor who has the capability of hard chrome plating the ID of aluminum valve bodies. These range in size from 1.00 in. to 8.00 in. The chrome will have to be .002 to .004 per side. We have the capability of honing or grinding to achieve the finished size and finish requirements but we be interested in finding a plating vendor with those capabilities. Thanks,
Ron
