ALUMINUM MATRIX COMPOSITE MATERIAL, SEMI-FINISHED PRODUCT CONSISTING OF THE ALUMINUM MATRIX COMPOSITE MATERIAL AND METHOD FOR PRODUCING THE SAME

摘要

The invention relates to an aluminum matrix composite material which is suitable for producing at least a friction ring of a brake disk. The aluminum matrix composite material comprises 20 to 40% by weight of aluminum, 10 to 30% by weight of silicon, and optionally 2 to 6% by weight of iron, 1 to 3% by weight of nickel, 1 to 3% by weight of manganese, 1 to 3% by weight of magnesium, as well as 15 to 25% by weight of silicon carbide particles and 15 to 25% by weight of aluminum nitride particles, based on a total weight of the aluminum matrix composite material. The invention further relates to a method for producing a semi-finished product consisting of the aluminum matrix composite material and to a semi-finished product consisting of the aluminum matrix composite material.
