- can strengthen the strength of 1235 pure aluminum tube is not high, but can be doubled by cold processing.And by adding magnesium, zinc, copper, manganese, silicon, lithium, scandium and other elements alloying, and then after heat treatment to further strengthen, its strength can be compared with high quality alloy steel.
Easily machined aluminum can be cast by any casting method.Aluminum has good plasticity and can be rolled into sheet and foil.Drawing pipe and wire;Extruded into various civil profiles;Most of the machine tools can achieve high speed for turning, milling, boring, planing and other mechanical processing.
-- on the surface of corrosion-resistant 1235 pure aluminum tube, a dense and firm AL2O3 protective film is easy to be formed.This protective film is only destroyed by the violent action of halide or base ions.As a result, aluminum has a good resistance to atmospheric (including industrial and Marine atmosphere) corrosion and water corrosion.It can resist the corrosion of most acids and organics, and can resist the corrosion of weak alkali solution with corrosion inhibitor.The corrosion resistance of aluminum alloy can be improved by adopting protective measures.
-- good conductivity of electricity and heat the conductivity of 1235 pure aluminum tube is second only to silver, copper and gold.At room temperature, the constant volume conductivity of electrical aluminum can reach 62%IACS. If the conductivity per unit mass is calculated, its conductivity is twice that of copper.
-- the reflectivity of the polished surface of highly reflective aluminum to white light is up to 80%. The higher the purity, the higher the reflectivity.At the same time, aluminum has good reflectivity to infrared ray, ultraviolet ray, electromagnetic wave and thermal radiation.
This is very valuable for some special purposes, such as instrument materials, shielding materials for electrical equipment, inflammable and explosion-prone production equipment.
Sound absorption is beneficial to interior decoration, and it can also be configured as damping alloy.
-- for high-energy neutrons, radiation-resistant aluminum has the same degree of neutron absorption cross section as other metals. For neutrons in the low energy range, its absorption cross section is small, second only to beryllium, magnesium, zirconium and other metals.The advantage of aluminum's resistance to nuclear radiation is that the induced radiation generated by irradiation decays rapidly.
-- beautiful aluminum and its 1235 pure aluminum tube have a silver-white luster due to their strong reflectivity.High finish and brightness can be achieved by machining.If anodized and colored, not only can improve the corrosion resistance, but also can obtain colorful, dazzling products.Aluminum is also an excellent substrate for producing paints.
-- heat treatment. Pure aluminum and rustproof aluminum can only be subjected to annealing treatment. Duralumin, forged aluminum and rustproof aluminum shall take quenching aging as the final heat treatment method
