—– Aluminum alloy extrusion profile classification

Scientific and reasonable classification of aluminum alloy profiles is conducive to scientific and reasonable selection of production technology and equipment, correct design and manufacture of tools and molds, and rapid treatment of extrusion workshop technical problems and production management problems.
1) According to the use or application characteristics, aluminum alloy profiles can be divided into general profiles and special profiles.
Special profiles can be divided into:
(1) Aerospace profiles: such as the integral wall panel with rib, I girder, wing girder, comb profiles, hollow beam profiles, etc., mainly used for aircraft, spacecraft and other aerospace aircraft stress structural components and helicopter shaped hollow rotor beams and runway.
(2) Vehicle profiles: mainly used for high-speed trains, subway trains, light rail trains, double-deck buses, luxury buses and trucks and other vehicles of the overall shape of the structure and important stress components and decorative components.
(3) Ship, weapon profile: mainly used for ships, warships, aircraft carriers, powerboats, hydrofoil superstructure and deck, partition, floor, as well as tanks, armored vehicles, personnel carriers and other integral shell, important force components, rocket and shell for medium and long range bullet, torpedo, mine shell and so on.
(4) Profiles for electronic and electrical, household appliances, post and telecommunications, and air conditioning radiators: mainly used as shell, heat dissipation parts, etc.
(5) petroleum, coal, electric power and other energy industry profiles as well as machinery manufacturing industry, mainly used as pipelines, supports, mining frame, transmission network, busbar and motor housing and a variety of mechanical components.
(6) Profiles for transportation, containers, refrigerators and highway Bridges: mainly used as packing boards, springboards, container frames, frozen profiles and car panels, etc.
(7) Profiles for civil buildings and agricultural machinery: such as profiles for doors and Windows of civil buildings, decorative parts, fences and large building structures, large curtain wall profiles and agricultural irrigation equipment parts, etc.
(8) Other use profiles: such as sports equipment, diving board, furniture component profiles, etc.
2) According to the shape and size change characteristics, profiles can be divided into constant section profiles and variable section profiles.
Constant section profiles can be divided into general solid profiles, hollow profiles, wall profiles and building door and window profiles. Variable section profiles are divided into phase variable section profiles and gradient profiles.
