The product is mainly used in friction industry to stabilized friction factor and reduce wear.During braking process,heat-singking capacity is greatly improved since metal softening process absorbs most of the heat from braking,and the softened metal could infiltrate brake surface squamosely to replace part of burnt binder.This improves braking capacity and prevents metal hot spot.
