Zusammenfassung:A copper-free friction material composition for a brake lining includes a fibrous form of an aluminum magnesium alloy, and a solid lubricant having a sulfur. The friction material composition can be disposed over at least a region of a backing plate of a brake pad to form a brake lining. The aluminum magnesium alloy contains about 4.5% to about 5.6% magnesium by weight. The friction material composition includes, by weight, about 5% to about 6% of the solid lubricant, about 5% to about 9.75% of the fibrous form of an aluminum magnesium alloy, about 7% to about 10% of an organic filler composition, and about 13% to about 17% of an abrasive composition, and can also include an inorganic filler, and a binder that develops the other components in the friction material composition into a thermosetting matrix. The friction material composition has a dynamic coefficient of friction of about 0.43.
