A pure aluminum tube is hollow metal tubing that is made of a lightweight and corrosion-resistant alloy of pure aluminium. It is used in applications such as air conditioning, furniture production, and drainage systems. In addition to being durable, it has the advantage of low weight and can be easily shaped into custom shapes.
The light silvery-white metal is very soft, but when mixed with copper, magnesium, silicon, and manganese it becomes very strong and versatile. It also has a high electrical conductivity, making it a desirable choice for wires, cables, and foil. Pure aluminum is nonmagnetic and nonsparking and ranks second among metals for malleability and sixth for ductility.
Aluminium tubes are produced in a variety of ways including extrusion, casting, rolling, and forging. Depending on the application they can be round, oval, rectangular, square or elliptical in diameter and wall thickness. They can be bent, welded and machined. Some common shapes include rings, washers, sleeves and sheaths.
The alloys used to produce aluminium tube are classified into different groups depending on their characteristics. The alloys 6061 and 2024 are often used in medium and high strength applications, respectively. Alloys 3003 and 5052 are used for applications that require good formability, dissolution, weldability, and corrosion resistance.
The finish of the aluminium tube can also vary. It can be polished or bright finished to have a shiny look or galvanized to add strength and durability. It can also be plated with a thin layer of another metal to improve its outer physical characteristics, like corrosion resistance or conductivity. The tubes can also be Finned or fluted, which allows them to easily dissipate heat. They can also be serializable, which means they can undergo sterilization techniques such as gamma irradiation, dry heat chemical, disinfection, and autoclaving.
