Al-based composites are among new industrial materials, which were developed in order to reduce the weight of vehicles in the aerospace industry. Quite recently, they have found application in the automobile industry due to a high specific strength combined with high wear resistance. Boron carbide or nitride containing composites may be applied both as wear resistance and radiation-protective materials. In our work we investigated composites based on structural Al alloys, filled with boron carbide (or nitride) and nanosized tungsten. Initial components were milled together in water-cooled planetary ball mill.
