Product Advantages
Corrosion resistance
The density of aluminum profiles is only 2.7g/cm3, which is about 1/3 of the density of steel, copper or brass (7.83g/cm3, 8.93g/cm3, respectively). Aluminum exhibits excellent corrosion resistance under most environmental conditions, including in air, water (or brine), petrochemicals, and many chemical systems.
Conductivity
Aluminum profiles are often chosen due to their excellent electrical conductivity. On an equal weight basis, the conductivity of aluminum is approximately 1/2 that of copper.
Thermal conductivity
The thermal conductivity of aluminum alloys is about 50-60% of that of copper, which is beneficial for the manufacture of heat exchangers, evaporators, heating appliances, cooking utensils, and automobile cylinder heads and radiators.
Non-ferromagnetic
Aluminium profiles are non-ferromagnetic, an important property for the electrical and electronic industries. Aluminium profiles are not self-igniting, which is important for applications involving handling or contact with flammable and explosive materials.
Machinability
The workability of aluminum profiles is excellent. Among various wrought and cast aluminum alloys, and in the various states in which these alloys are produced, the machining properties vary considerably, requiring special machine tools or techniques.
Formability
The specific tensile strength, yield strength, ductility and corresponding work hardening rate govern the variation in allowable deformation.
Recyclability
Aluminum is extremely recyclable, and the properties of recycled aluminum are almost indistinguishable from virgin aluminum.
Application
1. Architectural aluminum profiles (divided into doors and windows and curtain walls).
2. Radiator aluminum profile.
3. General industrial aluminum profiles: mainly used for industrial production and manufacturing, such as automated machinery and equipment, the skeleton of the cover, and the company's customized mold opening according to their own mechanical equipment requirements, such as assembly line conveyor belts, hoists, glue dispensers, Testing equipment, shelves, etc., are mostly used in the electronic machinery industry and clean rooms.
4. Aluminum alloy profiles for rail vehicle structure: mainly used in the manufacture of rail vehicle body.
5. Mounting aluminum profiles, making aluminum alloy picture frames, mounting various exhibitions and decorative paintings.
Raw Material
The aluminum profile models specified in the industry are usually 1024, 2011, 6063, 6061, 6082, 7075, etc., of which 6063/6061/6082 are the most common models. The difference between different aluminum profiles lies in the different proportions of various metal components.
60 series, 70 series, 80 series, 90 series are most commonly used in doors and windows, aluminum profiles, curtain walls and other buildings.
Other aluminum profiles are generally produced according to the special customized needs of customers, and can have different component contents, and technical specifications and drawings need to be provided.
