754铝板属于Almg3系列，镁合金含量要高于5052铝板，比5052铝板高一些。5754铝板属于中等强度铝合金板，镁合金含量2.6-3.6之间，具有较好的防锈耐腐蚀性能，阳极氧化表面无色差、加工性能、耐蚀性、高疲劳强度、高可焊性和中等静态强度，广泛应用于焊接结构、贮槽、压力容器、船舶结构与海上设施、汽车制造、运输槽罐等方面，由于硬度和抗拉强度的优势，近几天来在高铁屏障板方面用量较大。
754 aluminum plate belongs to almg3 series, and the magnesium alloy content is higher than 5052 aluminum plate, which is higher than 5052 aluminum plate. 5754 aluminum plate is a medium strength aluminum alloy plate with magnesium alloy content of 2.6-3.6. It has good rust and corrosion resistance, no color difference on anodized surface, excellent processing performance, excellent corrosion resistance, high fatigue strength, high weldability and medium static strength. It is widely used in welding structures, storage tanks, pressure vessels, ship structures and offshore facilities, automobile manufacturing In terms of transportation tanks and tanks, due to the advantages of hardness and tensile strength, the amount of high-speed rail barrier plate is large in recent days.
5083-O态铝板，O态更软一些，而罐盖需要折弯，隔板部分采用的也是5083-O态。此外，也有部分厂家采用5754H111铝板生产罐体。
5083-O state aluminum plate is softer in o state, while the tank cover needs to be bent, and the diaphragm part also adopts 5083-O state. In addition, some manufacturers use 5754h111 aluminum plate to produce tank bodies.
适用于罐车车体用的铝板主要是5系和6系相关产品。5系是以镁为主要合金元素的铝合金，6系是以镁、硅为主要合金元素并以Mg 2Si相为强化相的铝合金，其中主要合号包含：5052铝板、5083铝板、5754铝板、6061铝板和6082铝板。

Aluminum plates applicable to tank car body are mainly 5-series and 6-series related products. Series 5 is an aluminum alloy with magnesium as the main alloy element, and series 6 is an aluminum alloy with magnesium and silicon as the main alloy elements and Mg 2Si phase as the strengthening phase. The main alloy brands include 5052 aluminum plate, 5083 aluminum plate, 5754 aluminum plate, 6061 aluminum plate and 6082 aluminum plate.
5052铝板为AL-Mg系合金铝板，是应用广的一种防锈铝，强度与耐腐蚀性高。但不能热处理强化，在半冷作硬化时塑性尚好，冷作硬化时塑性低，可抛光。
5052 aluminum plate is Al Mg alloy aluminum plate, which is the most widely used antirust aluminum with high strength and corrosion resistance. However, it can not be strengthened by heat treatment. The plasticity is good in semi cold work hardening, low in cold work hardening and can be polished.
5083铝板中的镁合金强度高，热处理过的合金，具有良好的可加工性、耐腐蚀性和焊接性能。被广泛应用于交通车辆中，如船舶、飞机、车辆和压力容器(液罐车，冷藏车，冷藏集装箱)等。
The magnesium alloy in 5083 aluminum plate has high strength, and the heat-treated alloy has good machinability, corrosion resistance and welding performance. It is widely used in transportation vehicles, such as ships, aircraft, vehicles and pressure vessels (liquid tank vehicles, refrigerated vehicles, refrigerated containers), etc.
5754铝板具有中等强度、良好的耐蚀性、焊接性及易于加工成形等特点，是Al-Mg系合金中的典型合金。在国外，不同热处理状态的5754铝合金板材是汽车制造业(轿车车门、模具、密封件)、制罐工业所用的主要材料。
5754 aluminum sheet has the characteristics of medium strength, good corrosion resistance, weldability and easy processing and forming. It is a typical alloy in Al Mg alloys. In foreign countries, 5754 aluminum alloy plates with different heat treatment states are the main materials used in automobile manufacturing (car doors, molds, seals) and can making industry.
