Generally, due to the hardness factor, aluminum processing will choose aluminum and alloy together. Is it pure aluminum product, just like pure aluminum tube, no one has chosen it? This is based on individual needs. What are the advantages of pure aluminum tubes for pure aluminum tubes?

The density of pure aluminum tube is generally close to 2700kg/m3, which is about 35% of the density of iron. Pure aluminum can more than double its strength by cold working, and can be added by adding magnesium, zinc, copper, manganese, silicon, lithium, The element is alloyed and further strengthened by heat treatment, and its specific strength can be compared with high-quality alloy steel. Aluminum is easy to process: aluminum is cast by any casting method. The aluminum tube has good plasticity and can be rolled into thin plates and foils; drawn into pipes and filaments; extruded into various civil profiles; The maximum speed achieved is machining such as turning, milling, boring and planing.

Pure aluminum tube has good corrosion resistance, and the surface of aluminum and its alloy is easy to form a dense and firm Al2O3 protective film. This protective film will be destroyed only by the intense action of halogen ions or alkali ions. Therefore, aluminum has a good resistance to corrosion and water corrosion of the atmosphere, including industrial atmospheres and marine vapors. It can resist the corrosion of most acids and organic substances, and it can resist the corrosion of weak alkali solution by using corrosion inhibitor. It can improve the corrosion resistance of aluminum alloy by protective measures. Aluminum does not affect the low temperature. When the aluminum is below zero degrees Celsius, the strength and plasticity will not decrease with the decrease of temperature, but will increase.

The pure aluminum tube has good electrical and thermal conductivity and strong reflectivity: the polished surface of aluminum has a reflectivity of more than 80% for white light, and the higher the purity, the higher the reflectivity. At the same time, aluminum has good reflection properties for infrared rays, ultraviolet rays, electromagnetic waves, heat radiation, and the like.
