铝及铝合金:在汽车方面,用铝合金减轻汽车重量。1982型汽车的新V-8型发动机中,用铝制造主体部件其重量从90公斤减至19公斤。390合金正在替代压铸铝活塞用的380合金。四、六和八汽缸发动机的铝制入口联箱正在代替铸铁箱。福特公司打算用AA319合金取代V-6型发动机的铸铁汽缸盖。铝—石墨粒子混合物铸造已取得较好的耐磨性,该材料适合作4马力以下的静力柴 Aluminum and aluminum alloy: In the car, with aluminum alloy to reduce vehicle weight. In the 1982 model V-8 engine, the weight of the body made of aluminum was reduced from 90 kg to 19 kg. 390 alloy is replacing die-cast aluminum piston with 380 alloy. Aluminum four, six and eight cylinder engine inlet header is replacing the cast iron box. Ford plans to replace the cast iron cylinder head of the V-6 engine with AA319 alloy. Aluminum - graphite particle mixture casting has achieved good wear resistance, the material is suitable for 4 horsepower static diesel
