Mirror-smooth coating eliminates static buildup
Magnaplate HMF® is a proprietary, multi-step coating process that produces a mirror-smooth surface with a microfinish as low as 4 Ra. The coating can obtain a hardness of up to 68 Rc and can be applied to ferrous metal, copper or aluminum alloys. The purpose of the coating is to create a microfinish that produces a low coefficient of friction. Magnaplate HMF can operate in a range from as low as -250°F (-157°C) to as high as 950°F (510°C).
Salt spray per ASTM B-117 exceeds 336 hours when thickness of coating is 0.001 inches or greater. Magnaplate HMF provides a level of chloride protection better than chrome plating.
