Aluminum profile is an application product form of aluminum alloy. Aluminum alloy material or pure aluminum material can be called aluminum profile.
Aluminum profiles are aluminum rods with different cross-sectional shapes through hot melting and extrusion. Common aluminum profiles include aluminum plates, aluminum doors and windows, aluminum ceilings, aluminum curtain walls, aluminum castings (car engines, etc.), and space shuttle accessories, mechanical parts, electronic and electrical accessories, etc., all have the shadow of aluminum profiles. In order to improve the decorative effect, enhance the corrosion resistance and prolong the service life, aluminum profiles generally have to be surface treated. 1. Classification according to surface treatment requirements (1) Anodized aluminum material (2) Electrophoretic painted aluminum material (3) Powder sprayed aluminum material (4) Fluorocarbon paint sprayed aluminum material (5) Wood grain transfer aluminum material, etc. 2. Features of aluminum profiles: 1. The density of corrosion-resistant 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). Under most environmental conditions, including air, water (or salt water), petrochemicals and many chemical systems, aluminum can show excellent corrosion resistance. 2. Electrical conductivity Aluminum profile is often selected because of its excellent electrical conductivity. On the basis of equal weight, the conductivity of aluminum is nearly twice that of copper. 3. Thermal conductivity The thermal conductivity of aluminum alloy is about 50-60% of copper, which is very beneficial for the manufacture of heat exchangers, evaporators, heating appliances, cooking utensils, and automobile cylinder heads and radiators. 4. Non-ferromagnetic aluminum profile is non-ferromagnetic, which is an important feature for the electrical and electronic industries. Aluminum profiles are not spontaneously combustible, which is important for applications involving handling or contact with flammable and explosive materials. 5. Machinability The machinability of aluminum profiles is excellent. In various deformed aluminum alloys and cast aluminum alloys, as well as in the various states that these alloys have after being produced, the machining characteristics change considerably, which requires special machine tools or technology. 6. Formability The specific tensile strength, yield strength, ductility and corresponding work hardening rate dominate the change in allowable deformation. 7. Recyclability Aluminum has extremely high recyclability, and the characteristics of recycled aluminum are almost indistinguishable from primary aluminum. These characteristics of aluminum profiles can be used for the following purposes: Including aluminum profiles for doors and windows and curtain walls for construction, aluminum profiles for aerospace and aviation, aluminum profiles for transportation, special radiator aluminum profiles for CPU radiators, aluminum alloy shelf aluminum profiles, Furniture, solar energy, display equipment, medical equipment, automated machinery and equipment, the skeleton of the enclosure, and companies customize mold openings according to their own mechanical equipment requirements, such as aluminum profiles for assembly line conveyor belts, hoists, dispensers, and testing equipment.
Aluminum alloy
Aluminum alloy is made of pure aluminum by adding some alloying elements, such as aluminum-manganese alloy, aluminum-copper alloy, aluminum-copper-magnesium hard aluminum alloy, and aluminum-zinc-magnesium-copper super hard aluminum alloy. Aluminum alloy has better physical and mechanical properties than pure aluminum: easy processing, high durability, wide application range, good decorative effect, and rich color. Aluminum alloy is the most widely used non-ferrous metal structural material in industry, and it has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industries. Aluminum alloys are divided into rust-proof aluminum, duralumin, super-duralumin and other types. Each type has its own range of use and has its own code for users to choose. 1. Classification characteristics of aluminum alloy According to the characteristics of production process, aluminum alloy is divided into two types: deformed aluminum alloy and cast aluminum alloy. (1) Wrought aluminum alloy It can be divided into anti-rust aluminum alloy, hard aluminum alloy, super hard aluminum alloy and wrought aluminum alloy. They have their own characteristics and have different application ranges. The deformed aluminum alloy undergoes hot and cold pressure processing such as rolling and extrusion to make various profiles such as plates, rods, wires, and tubes. ①The anti-rust aluminum alloy belongs to the aluminum-manganese series and the aluminum-magnesium series alloy. It has moderate strength, excellent plasticity, and good corrosion resistance. It is an aluminum alloy that can be strengthened by heat treatment and is used to make good corrosion resistance. Containers, fuel tanks, deep-drawn parts, etc. ②Duralumin alloy, which belongs to aluminum-copper-magnesium alloy, can be improved by quenching and aging treatment, and has poor corrosion resistance. It is used to manufacture aircraft beams, shelves, air propellers, etc., and is also obtained in instrument manufacturing.了 Application. ③Super hard aluminum alloy, which belongs to the aluminum-copper-magnesium-zinc alloy formed by adding zinc on the basis of hard aluminum alloy. It can be heat treated to increase the strength, and its corrosion resistance is poor, and it is used for aircraft with greater stress Structural parts, such as aircraft girder, landing gear, etc. ④Wrought aluminum alloys, mostly aluminum-copper-magnesium-silicon or aluminum-copper-magnesium-nickel-iron alloys, have good thermoplasticity and corrosion resistance, and have good pressure processing performance under hot conditions. The best can be obtained through heat treatment. Good strengthening effect. It is mainly used in the aviation instrument manufacturing industry to manufacture forgings or stampings with complex shapes, light weight and high strength, such as impellers, conductive wheels, and rocker arms of aircraft operating systems. Aluminum profile is a kind of material, and aluminum alloy is a kind of metal.
