Aluminium is used in various industries due to its low density and passivation process. When metal parts are used in manufacturing and construction, heating strength is often a key factor. This also applies to metal pipes. Resistance to both bending and deformation is necessary, and aluminium pipe can achieve this application. Aluminium pipe is lightweight, so the unit weight volume of aluminium pipe is larger than that of steel. Many products prefer to use lighter pipes, especially those that need to be moved, such as wheelchairs and outdoor furniture.
Aluminium pipe is a type of non-ferrous metal tube, which refers to metal tubular materials that are processed by pure aluminium or aluminium alloy extrusion along the full length of their hollow vertical axis. Aluminium pipe is a high-strength hard aluminium, which can be heat-treated for strengthening. Its plasticity is moderate when annealed, quenched, and in a hot state. Its spot welding and welding properties are good, and there is a tendency to form an intergranular crack when welding with gas welding and argon arc welding. After quenching and cold work hardening, the cutting performance of aluminium pipe is still good, but it is not good in the annealed state. The corrosion resistance is not high, and the anodizing treatment and painting method or surface wrapping with aluminium layer are often used to improve the corrosion resistance.
Heat exchangers: Aluminium pipes are strong thermal conductors. Among similar conductors, 1000 series aluminium alloy is the best choice. Usually, pipes are carriers that transfer heat from one place to another. The following products are available in the heat exchanger field: engines, refrigerators, air conditioning and heating systems, ventilation, solar energy, and steam generators, reboilers.
Transportation (including aviation and aerospace): The versatility of aluminium tube is very suitable for vehicles such as automobiles, aviation and aerospace, and rail transportation. Because they need a sturdy but lightweight material component to help complete the task. This includes: body, railing, travel, fuel pipe, hydraulic system, and frame.
Frame structure or public utilities: You may see many billboards, road signs, etc. on the highway, including guardrails and other signs. These facilities are mostly made of the aluminium tube, with corrosion resistance and low maintenance costs. Other public applications using aluminium pipes include: building decoration, outdoor structures, frames, and supports.
Others: There are too many uses of the aluminium pipe. The following mainly lists the ones that we don't pay much attention to, but can be contacted every day: electronic products, medical equipment, accessories and fasteners (safety fences and store fixtures), pressure vessels (such as fire extinguishers, submarines, refineries, and storage tanks).
