1系列铝卷为纯铝，铝含量达99.0%以上。
1.密度很小。纯铝的比重为2.71。在相同体积下，系列1铝板的重量仅为铁的35%。
2.它可以得到加强。1系列铝板的强度可通过冷加工提高，达到1倍以上。
3.1系列铝板易于加工，塑性好，更适合于锯、剪、铣、镗、刨、车等机械加工。

4.耐腐蚀性。1系列铝板表面自然形成致密的氧化铝保护膜，无需特殊处理，不易损坏。因此，1系列铝板具有良好的耐大气（包括工业大气和海洋大气）腐蚀和水腐蚀性能。
5.如果没有低温脆性，1系列铝板的强度和塑性不会因温度的降低而降低。零下，温度越低，强度和塑性越高。
6.良好的导电性和导热性。在金属中，铝的导电性和导热性仅次于金、银和铜。
7.反射率好。抛光后，1系列铝板表面对光的反射率可达80%以上。铝的纯度越高，反射率越高。除可见光外，铝对红外线、紫外线、电磁波和热辐射具有良好的反射率。
铝卷中3系列铝卷的性能特点：
3系列铝卷属于铝锰合金，主要成分为锰，属于热处理非强化合金。
1.3系列铝线圈合金塑性高，焊接性能好；
2.强度高于工业纯铝，耐蚀性与工业纯铝相近。铝镁合金称为防锈铝合金。
3.3系列铝卷合金在退火状态下具有良好的塑性，退火后具有良好的拉深性能。主要用于制造汽车、飞机油箱、油管、集装箱、罐体、机械零件等领域。
铝卷中8系列铝卷的性能特点：
8系列铝线圈属于铝锂合金，其主要成分是锂，因为锂是自然界中最轻的金属。铝板加锂后，在保证铝板强度的同时，可有效降低铝板比重
1.重量轻。铝锂合金最大的特点是质量。锂的加入使铝锂合金的质量比大多数金属轻。随着锂含量的增加，其质量将进一步降低。这一特征吸引了许多科学家对其进行研究。
2.高强度。铝锂合金具有较高的强度，其强度不会随锂含量的增加而发生显著变化，加入铜、镁、锌等元素可以进一步提高合金的强度。
3.高刚性。铝锂合金具有较高的刚度和较强的变形抗力。随着锂含量的增加，其刚度将进一步提高。
4.耐腐蚀性。与纯铝相比，铝锂合金具有良好的耐蚀性和较强的环境适应性。
5.抗疲劳。金属疲劳是限制铝板应用范围的主要因素之一，铝锂合金具有优异的抗疲劳性能和较长的使用寿命。
6.延展好。铝锂合金具有良好的延展性，有效降低了铝锂合金的加工难度。

1 series aluminum coil belongs to pure aluminum, and its aluminum content reaches more than 99.0%.

1. The density is small. The specific gravity of pure aluminum is 2.71. Under the same volume, the weight of series 1 aluminum plate is only 35% of that of iron.
2. It can be strengthened. The strength of 1-series aluminum plate can be improved by cold processing, up to more than 1 time.
3. Easy to process, 1-series aluminum plate has good plasticity and is more suitable for machining, such as sawing, shearing, milling, boring, planing, turning, etc.
4. Corrosion resistance. A dense aluminum oxide protective film will be naturally formed on the surface of the 1-series aluminum plate without special processing, which is difficult to be damaged. Therefore, the 1-series aluminum plate has good resistance to atmospheric (including industrial atmosphere and marine atmosphere) corrosion and water corrosion.
5. Without low temperature brittleness, the strength and plasticity of 1-series aluminum plate will not be reduced due to the reduction and reduction of temperature. Below zero, the lower the temperature, the higher the strength and plasticity.
6. Good conductivity and thermal conductivity. Among metals, the conductivity and thermal conductivity of aluminum are second only to gold, silver and copper.
7. Good reflectivity. After polishing, the reflectivity of 1-series aluminum plate surface to light can reach more than 80%. The higher the purity of aluminum, the higher the reflectivity. In addition to visible light, aluminum has good reflectivity to infrared, ultraviolet, electromagnetic wave and thermal radiation.
Performance characteristics of 3 series aluminum coil in aluminum coil:
3 series aluminum coil belongs to aluminum manganese alloy, the main component is manganese, which belongs to heat-treated non strengthening alloy.
1. 3 series aluminum coil alloy has high plasticity and good welding performance;
2. The strength is higher than that of industrial pure aluminum, and the corrosion resistance is similar to that of industrial pure aluminum. It is called antirust aluminum alloy with aluminum magnesium alloy.
3. 3 series aluminum coil alloy has good plasticity in annealed state and good deep drawing property after annealing. It is mainly used in the manufacturing of automobile, aircraft fuel tank, oil pipe, container, tank body, mechanical parts and other fields.
Performance characteristics of 8 series aluminum coil in aluminum coil:
8 series aluminum coil belongs to aluminum lithium alloy, and its main component is lithium, because lithium is the lightest metal in nature. After adding lithium to aluminum plate, it can effectively reduce the specific gravity of aluminum plate while ensuring the strength of aluminum plate
1. Light weight. The biggest characteristic of Al Li alloy is its quality. The addition of lithium makes the mass of aluminum lithium alloy lighter than that of most metals. With the increase of lithium content, its mass will further decrease. This feature has attracted many scientists to study it.

3. High rigidity. Al Li alloy has high stiffness and strong deformation resistance. Its stiffness will be further improved with the increase of lithium.
4. Corrosion resistance. Compared with pure aluminum, Al Li alloy has good corrosion resistance and strong environmental adaptability.
5. Anti fatigue. Metal fatigue is one of the main factors limiting the application range of aluminum plate, and aluminum lithium alloy has excellent fatigue resistance and long service life.
6. Good ductility. Al Li alloy has good ductility, which effectively reduces the processing difficulty of Al Li alloy.
