您在生活中有使用过保温铝卷吗？您知道它优越的性能特点是怎样的吗？为了让大家更好的了解，下面铝卷生产厂家为您讲讲。
Have you ever used thermal insulation aluminum coils in your life? Do you know what its superior performance features are? In order to give you a better understanding, the aluminum coil manufacturer will tell you about it.
1．保温铝卷密度小：纯铝的密度接近2700kg/m3,约为铁的密度的35%。
1. The density of thermal insulation aluminum coil is small: the density of pure aluminum is close to 2700kg/m3, which is about 35% of the density of iron.
2．保温铝卷可强化：纯铝通过冷加工可使其强度提高一倍以上。而且可通过添加镁、锌、铜、锰、硅、锂、钪等元素合金化，再经过热处理进一步强化，其比强度可与的合金钢媲美。
2. Thermal insulation aluminum coil can be strengthened: the strength of pure aluminum can be more than doubled by cold processing. Moreover, it can be alloyed by adding magnesium, zinc, copper, manganese, silicon, lithium, scandium and other elements, and further strengthened by heat treatment. Its specific strength is comparable to that of excellent alloy steel.
3．保温铝卷易加工：铝用用任何一种铸造方法铸造。铝的塑性好，可轧成薄板和箔；拉成管材和细丝；挤压成各种民用的型材；可以大多数机床所能达到的大速度进行车、铣、镗、刨等机械加工。
3. Easy processing of thermal insulation aluminum coil: aluminum is cast by any casting method. Aluminum has good plasticity and can be rolled into thin sheets and foils; Drawn into pipes and filaments; Extruded into various civil profiles; It can be used for turning, milling, boring, planing and other machining at the high speed that most machine tools can achieve.

4．保温铝卷耐腐蚀：铝及其合金的表面，易生成一层致密、牢固的Al2O3保护膜。这层保护膜只有卤素离子或碱离子的激烈作用下才会遭到破坏。因此，铝有很好的耐大气（包括工业性大气和海洋大汽）腐蚀和水腐蚀的能力。能抵抗多数酸和有机物的腐蚀，采用缓蚀剂，可耐弱碱液腐蚀；采用保护措施，可提高铝合金的抗蚀能力。
4. Corrosion resistance of thermal insulation aluminum coil: A dense and firm Al2O3 protective film is easily formed on the surface of aluminum and its alloy. This protective film will be damaged only under the intense action of halogen ions or alkali ions. Therefore, aluminum has good resistance to atmospheric corrosion (including industrial atmosphere and marine steam) and water corrosion. It can resist the corrosion of most acids and organic substances, and can resist the corrosion of weak alkali solution by using corrosion inhibitors; The corrosion resistance of aluminum alloy can be improved by adopting protective measures.
5．无低温脆性：铝在摄氏零度以下，随着温度的降低，强度和塑性不公不会降低，反而提高。
5. No low-temperature brittleness: aluminum is below zero centigrade. With the decrease of temperature, the unfairness of strength and plasticity will not decrease, but will increase.
6．导电、导热性好：铝的导电、导热性能公次于银、铜和金。
6. Good conductivity and thermal conductivity: aluminum is inferior to silver, copper and gold in conductivity and thermal conductivity.
7．反射性强：铝的抛光表面对白光的反射率达80%以上，纯度越高，反射率越高。同时，铝对红外线、紫外线、电磁波、热辐射等都有良好的反射性能。
7. Strong reflectivity: the reflectivity of aluminum polished surface to white light is more than 80%. The higher the purity, the higher the reflectivity. At the same time, aluminum has good reflective performance to infrared ray, ultraviolet ray, electromagnetic wave, thermal radiation, etc.
8．无磁性、冲击不生火花。
8. Non magnetic, impact free sparks.
