Alumina
High melting point, thermal strength, high hardness and good thermal stability, adding alumina to
the friction material can effectively improve the normal temperature, high temperature friction
coefficient, which to reduce the heat caused by the recession due to friction plate cracking has
certain effect. It is not suit to add superfluous alumina in amount of the specific formula ,
general control in 5% days, more than 325 mesh to avoid to increase abrasion and damage of duality.
