Aluminum profiles are classified according to their different applations:
1. Architectural aluminium profiles (divided into doors/ windows and curtain walls aluminium ).
2. Radiator Aluminum Profile
3. General industrial aluminium profiles: mainly used for industrial production and manufacturing, such as automation machinery and equipment, the framework of the cover, and companies according to their own mechanical equipment requirements custom-made die opening, such as pipeline conveyor belt, hoist, dispensing machine, testing equipment, shelves, etc., the electromechanical industry and dust-free room are mostly used.
4. Aluminum alloy profile for railway vehicle structure: Mainly used in the manufacture of Railway Vehicle Body.
5. Mounting aluminium profiles, making aluminium alloy picture frames, mounting various exhibitions and decorative paintings.
Brand: 5A02 5754 5A06
Standard: GB/T 6893-2000
Characteristics and scope of application:
Compared with 3A21, 5A02 has higher strength, especially higher fatigue strength; similar to 3A21,5A02 aluminum has higher plasticity and corrosion resistance; heat treatment can not be strengthened, contact welding and hydrogen atom welding have good weldability, and there is a tendency to crystalline cracks in argon arc welding; alloy has better machinability in cold and Semi-cold hardening, poor machinability in annealing and polishing.
5754 aluminum is widely used in welding structures, tanks, pressure vessels, ship structures and offshore facilities, transport tanks and tanks, as well as in occasions requiring excellent processing performance, excellent corrosion resistance, high fatigue strength, high weldability and medium static strength.

Specification aluminum plates for heat treatment:
1) Homogenization annealing: heating 440 C; holding 12-14 h; air cooling.
2) Rapid annealing: heating 350-410 C; holding time 30-120 min; air or water cooling.
3) High temperature annealing: heating 350-420 C; when the thickness of finished product is more than 6 mm or less than 6 mm, the holding time is 2-10 minutes or 10-30 minutes; air cooling.
4) Low-temperature annealing: heating 250-300 or 150-180 degrees; holding time 1-2 hours, air-cooled.
