材质可以理解为材料质量，但是在铝合金里面材质主要指的是合金含量，也就是我们常说的5052铝板，5083铝板等均是指的材质，而在材质证明中的材质还包括力学性能这一个因素，综合而言我们可以讲材质理解为两个部分，个部分是化学成分也就是我们常说的合金含量另外一种及时力学性能，包括延伸率和抗拉强度两个指标。
Material quality can be understood as material quality, but in aluminum alloy, material mainly refers to the alloy content, that is, 5052 aluminum plate and 5083 aluminum plate, which we often refer to, and the material in the material certificate also includes the factor of mechanical properties. Generally speaking, we can understand material as two parts, The first part is the chemical composition, that is, the alloy content, another kind of timely mechanical properties, including elongation and tensile strength.
其实在常规术语中我们通常默认材质仅仅指的是合金含量，也就是如果要求材质是某一种合号那么化学成分必须能够满足该牌号的标准，而力学性能通常体现在了状态方面，比如在标准的铝板订单中会出现5052-H32，其中5052指的是材质，而H32指的是力学性能。
In fact, in conventional terms, we usually default that the material only refers to the alloy content, that is, if the material is required to be an alloy brand, the chemical composition must meet the standard of the brand, and the mechanical properties are usually reflected in the state. For example, 5052-H32 will appear in the standard aluminum plate order, in which 5052 refers to the material and H32 refers to the mechanical properties.

如何来确认材质是否合格：这一点需要的仪器设备才能够进行确认，实际上很多用户都不会检验而销售商也不敢用其它材质替代，所以材质往往还是依靠诚信来保证的，当然如果对于要求较为严格或者数量较大的订单也可以委托第三方检测结构进行材质检测。
How to confirm whether the material is qualified: this can only be confirmed by professional instruments and equipment. In fact, many users will not inspect it, and sellers dare not replace it with other materials, so the material is often guaranteed by integrity, Of course, for orders with strict requirements or large quantities, a third-party testing structure can also be entrusted for material testing.
铝的熔点低，铸造性能好。铝的力学性能与其纯度有很大关系，工业铝板强度低，但铝和某些合金元素组成的铝合金，不仅在某种程度上仍保持着铝固有的特点，同时又显著提高了它的硬度和强度。某些铝合金用作结构材料时，其强度可超过一般结构钢；别一些铝合金用作模具材料时，其使用寿命可超过一般模具钢。铝和多种铝合金均有的延展性，可以进行各种塑性加工。
Aluminum has low melting point and good casting performance. The mechanical properties of aluminum are closely related to its purity. The strength of industrial aluminum plate is low, but the aluminum alloy composed of aluminum and some alloy elements not only maintains the inherent characteristics of aluminum to some extent, but also significantly improves its hardness and strength. When some aluminum alloys are used as structural materials, their strength can exceed that of general structural steel; When some aluminum alloys are used as die materials, their service life can exceed that of general die steel. Aluminum and a variety of aluminum alloys have excellent ductility and can be processed in a variety of plasticity.
任何一种铝合金的机械加工性能都优于钢和纯铝，但各种变形铝合金与铸造合金的机械加工性能能有很大的差别。铝及铝合金是属于容易成形的金属材料之一，但是铝合金所容许的形变量受其化学成份、品级及其热处理的影响。由于铝合金的机械强度和加工硬化率均较低，因此与其他金属的成形性能有所不同。
The machinability of any kind of aluminum alloy is better than that of steel and pure aluminum, but the machinability of various deformed aluminum alloys and cast alloys can be very different. Aluminum and aluminum alloy are one of the most easily formed metal materials, but the allowable deformation of aluminum alloy is affected by its chemical composition, grade and heat treatment. Because the mechanical strength and work hardening rate of aluminum alloy are low, its formability is different from that of other metals.
机械制造业广泛用铝板制造车轮、滑轮、离心机、通风机、起重机及泵的零部件、活塞和发动机气缸，以及铝板冲压件等。
The machinery manufacturing industry widely uses aluminum plates to manufacture wheels, pulleys, centrifuges, ventilators, crane and pump parts, pistons and engine cylinders, as well as aluminum plate stamping parts.
这是由于铝及铝合金的特点不仅密度小，而且能具有所要求的强度和硬度，从而能降低机械运转中的能量消耗，或者在使用相同能量的条件下大大地提高运转速度，也相对一延长了机件的使用寿命。同时，整个机器的重量减轻、尺寸减小后，更能适应生产、运输、安装和操作。
This is because the characteristics of aluminum and aluminum alloy not only have low density, but also have the required strength and hardness, which can reduce the energy consumption in mechanical operation, or greatly improve the operation speed under the condition of using the same energy, but also relatively prolong the service life of the parts. At the same time, after the weight and size of the whole machine are reduced, it can be more suitable for production, transportation, installation and operation.
归纳起来，工业铝板的用途主要为以下几个行业：建筑工业、容器包装、交通运输、电力工业、食品工业、机械设备、耐用消费品行业以用其他类等。近20年来，建筑、汽车、包装用铝已成为工业发达国家的铝材三大用途。
The following industries are mainly used for industrial and transportation equipment, such as aluminum and other durable goods. In the past 20 years, aluminum for construction, automobile and packaging has become the three major uses of aluminum in industrial developed countries.
