A, refers to different
1, aluminum tubes: the use of pure aluminum or aluminum alloy by extrusion processed into the full length of its longitudinal hollow metal tubular materials.
2, aluminum alloy tube: the use of aluminum and other metals are processed into a medium control of the metal tubular materials.
Two, different characteristics
1, aluminum tube: a high-strength hard aluminum, heat treatment can be strengthened, in the annealed, just quenched and hot state of plasticity in the medium, spot welding weldability is good, with the gas welding and argon arc welding aluminum tubes have a tendency to form intergranular cracks; aluminum tubes in the quenching and cold hardening of the machinability is still good, in the annealed state is bad.
2, aluminum alloy tube: aluminum alloy density is low, but the strength is relatively high, close to or more than high-quality steel, good plasticity, can be processed into a variety of profiles, with excellent electrical conductivity, thermal conductivity and corrosion resistance, industry is widely used, the use of second only to steel.
Three, different uses
1, aluminum tube: used in various industries, such as: automobiles, ships, aerospace, aviation, electrical appliances, agriculture, electromechanical, household, etc.
2, aluminum alloy tubes: aviation, aerospace, automotive, machinery manufacturing, shipping and chemical industry has been a large number of applications.
