At present, there are three commonly used thermal insulation aluminum coils, namely 1 series pure aluminum coil, 3 series aluminum manganese alloy aluminum coil and 5 series aluminum magnesium alloy aluminum coil. These three kinds of thermal insulation aluminum coils are widely used in thermal insulation, anti-corrosion and anti-rust projects of buildings, equipment, walls, pipes, etc. So, what are the differences between these three types of thermal insulation aluminum coils, and which environments are they suitable for?
The difference between 1 series thermal insulation aluminum coil and ordinary aluminum coil:
The price of the 1-series aluminum coil is relatively cheap, and its application range is naturally wider. For example, the 1-series aluminum coil can be competent for the waterproofing of ordinary buildings and the thermal insulation and rust prevention of municipal pipelines. However, the 1-series aluminum coils are not resistant to acid and alkali corrosion, and they are powerless for the insulation of equipment and pipelines in power plants and chemical plants.
The difference between 3 series thermal insulation aluminum coil and ordinary aluminum coil:
The price of the 3 series aluminum coil is slightly higher than that of the 1 series aluminum coil, and it is a kind of thermal insulation aluminum coil with mature technology. The strength of the 3-series aluminum coil is slightly higher than that of the 1-series aluminum coil, and it has better acid and alkali corrosion resistance.
The difference between the 5 series thermal insulation aluminum coil and the ordinary aluminum coil:
The price of the 5 series aluminum coil is higher, and its performance is also the best among the three. 5 series aluminum coils have high strength, good plasticity and corrosion resistance, good relief from fatigue, and can be welded and processed. They are regarded as more promising thermal insulation aluminum coils. 5 series aluminum coils are used in occasions with strict requirements on the performance of aluminum coils, such as height, fatigue resistance, corrosion resistance, etc., and are widely used in nuclear power, aviation and aerospace fields.
