在众多采用新型材料的车辆中,有些采用低合金钢、高抗拉强度钢、超高强度钢作为车身主要材料,还有些车身局部或全部采用铝质板材,新材料的应用给车身修复带来了新的难题。目前,铝合金材料按延展特点可分为热处理系列和非热处理系列。非热处理系列主要包括纯铝1000系列、铝锰合金3000系列、铝硅合金4000系列、铝镁合金5000系列等;热处理系列主要包括铝铜合金2000系列、铝硅镁合金6000
Among the many vehicles using new materials, some adopt low-alloy steel, high tensile strength steel and ultra-high-strength steel as the main body materials, and some of the body parts adopt aluminum plates partially or totally. The application of new materials brings the body repair The new problem. At present, the aluminum material can be divided into heat treatment and non-heat treatment series according to the extension characteristics. Non-heat treatment series include 1000 series of pure aluminum, aluminum-manganese alloy 3000 series, 4000 series of aluminum-silicon alloy, 5000 series of aluminum-magnesium alloy; heat treatment series include aluminum-copper alloy 2000 series, Al-Si-Mg alloy 6000
