Metallic brass, copper, bronze, zinc, iron and iron alloy powders
BRASS POWDER It has similar proprieties to fiber and chips, but has no cosmetic effect . It cannot improve mechanical characteristics, but allows more homogeneous distribution than fiber and chips. We suggest using it in formulations between 3-10% (by wt).
COPPER POWDER It is a good thermal conductor and conducts heat away from the friction interface. A high copper percentage may cause counter face wear.
