一、铝合金工业先进各国压铸铝合金的数量都在增加,主要因为它质轻,而材料来源又此较丰富.另外,也可以大量利用航空工业上的废料来配制合金.铝合金较之锌合金尚有下列各种优点:1.耐腐蚀性优越,铸件经打光后,可保持其光洁度;2.铸件尺寸很稳定;3.在低温时机械性能仍保持不变;4.导电率和导热率很高.压铸用铝合金,根据化学成分不同,大致可分成以下几类:
First, the advanced industrial countries Aluminum die-casting aluminum are increasing in the number, mainly because of its light weight, and the material sources and more abundant.In addition, you can also make extensive use of aviation industry waste to formulate the alloy aluminum alloy compared to zinc The alloy also has the following advantages: 1. Superior corrosion resistance, casting after polishing, to maintain its finish; 2. Casting size is very stable; 3. The mechanical properties at low temperatures remain unchanged; 4. Conductivity and High thermal conductivity. Aluminum die-casting, according to different chemical composition, can be roughly divided into the following categories:
