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 materials with different cross-sectional shapes through hot melting and extrusion of aluminum rods. Common aluminum profiles include aluminum plates, aluminum doors and windows, aluminum ceilings, aluminum curtain walls, car power amplifier radiators, etc. As well as space shuttle accessories, mechanical accessories, electronic and electrical accessories, there are aluminum profiles.
According to surface treatment requirements, there are anodized aluminum materials, electrophoretic painted aluminum materials, powder sprayed aluminum materials, fluorocarbon paint sprayed aluminum materials, wood grain transfer aluminum materials, dyed aluminum materials, brushed aluminum materials, electrolytic polished aluminum materials, etc. .
Features of aluminum profile:
1. Corrosion resistance
The density of aluminum profile 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. 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 to the manufacture of heat exchangers, evaporators, heating appliances, cooking utensils, and automobile cylinder heads and radiators.
4. Non-ferromagnetic
Aluminum profiles are 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 the aluminum profile is excellent. In various deformed aluminum alloys and cast aluminum alloys, as well as in the various states these alloys have after being produced, the machining characteristics vary 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 transportation, aluminum profiles for transportation, special radiator aluminum profiles for automotive power amplifier radiators, aluminum alloy shelf aluminum profiles, furniture, solar energy, display equipment, medical equipment, automated machinery and equipment , The skeleton of the enclosure and the mold openings are customized by each company according to their own mechanical equipment requirements, such as aluminum profiles for assembly line conveyor belts, hoists, glue 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.
Aluminum alloy classification characteristics
According to the characteristics of the production process, aluminum alloy is divided into two types: deformed aluminum alloy and cast aluminum alloy.
1. Deformed 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 produce various profiles such as plates, rods, wires, and tubes.
①The anti-rust aluminum alloy belongs to the aluminum-manganese series and aluminum-magnesium series alloys. 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 quenched, aging treatment, etc. to increase the strength, and its corrosion resistance is poor. 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 beams, 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. Good strengthening effect. 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.
2. Cast aluminum alloy
It can be divided into aluminum-silicon series, aluminum-copper series, aluminum-magnesium series and aluminum-zinc series, etc. It has good casting performance and is aluminum alloy of various shapes manufactured by various casting methods.
Aluminum profile is a kind of material, and aluminum alloy is a kind of metal.
