Zinc coating on aluminum for non-conductivity

2004

Hi,

I am looking for a material to make a machine table for EDM machining. this requires the machine table to be non conductive. At the same time, mounting the work piece on the plastic part is not accurate. I would like to know more abt zinc plating on aluminum? does it make aluminum non conductive. Sandwiching a plastic sheet between two metal plates is one solution. But can anybody give me more info on how to make aluminum/stainless steel non conducting

Thanx in advance

Zinc is conductive. Anodizing your aluminum will provide a non-conductive surface. Hard anodize will have better dielectric properties and have added benefits abrasion resistantance.

You can anodize the aluminum, that will make it non-conductive, harder, more corrosion resistant, and let you dye the part for cosmetic reasons.
