专利申请范围所申请专利的铝合金具有强度高,深冲加工性能好的特点。其化学成分为:Mg0.8～2.2%,Mn0.1～0.7%,Cu0.4～1.0%,Ti<0.3%,其余是铝及铝锭中所含的杂质。发明的详细说明本发明所涉及的装啤酒和清凉饮料用的全部铝制深冲罐所使用的材料。现在制造深冲罐用的所有铝合金都是Al-Mg-Mn系合金,制造深冲罐所用的材料必须具备如下性能:(1)强度高;(2)制耳率低;(3)深冲加工性能好。材料的强度高,深冲加工性能好,能使罐壁变薄;制耳率低能节省材料。这样,有可能降低材料成本。
Patented patent application of the aluminum alloy with high strength, deep drawing processing performance characteristics. Its chemical composition: Mg 0.8 ~ 2.2%, Mn 0.1 ~ 0.7%, Cu 0.4 ~ 1.0%, Ti <0.3%, the balance of impurities contained in aluminum and aluminum ingot. DETAILED DESCRIPTION OF THE INVENTION Materials used in all aluminum deep-drawn cans for beer and soft drinks according to the present invention. Now all the aluminum alloys used in making deep-drawing cans are made of Al-Mg-Mn alloys. The material used for making deep-drawing cans must have the following properties: (1) high strength; (2) low ear-making rate; Chong processing performance is good. High strength of the material, deep drawing processing performance, thinning the tank wall; low ear rate can save material. In this way, it is possible to reduce material costs.
