What is Aluminum Bar?
Aluminum bar is a kind of bar shaped aluminum profile product which is produced from the raw material aluminum through a certain manufacturing process. Aluminum bars are widely used in decoration, packaging, construction, transportation, electronics, aviation, aerospace, weapons and other industries.
According to different processing technologies, aluminum bars can be divided into cast aluminum bars, forged aluminum bars, drawn aluminum bars and extruded aluminum bars.
According to the extrusion profile, aluminum bars can be divided into aluminum round bars, aluminum square bars, hexagonal aluminum bars and special-shaped aluminum bars.
According to the diameter, aluminum bars can be divided into ordinary aluminum bar and super large diameter aluminum bar.
Classification of Aluminum Bars by Processing Technology
Extruded Aluminum Bar
Extrusion process is the most commonly used manufacturing process in aluminum bar processing. It is to form and extrude aluminum bars on metal materials at a certain temperature by the virtue of the good plasticity of raw materials.
Production process flow of extruded aluminum bar:
- Preparation before extrusion;
- Extrusion;
- Stretching and Straightening;
- Sawing finished products, trimming and framing.
Common alloy of extruded aluminum bar: 1050, 1060, 2011, 2014, 2017, 2024, 2618, 5052, 5083, 5086, 5454, 5754, 6061, 6063, 6082, 7003, 7022, 7050, 7055, 7075.
Aluminum billets
The casting aluminum bar has the following production steps. First pure aluminum or aluminum alloy ingots are prepared according to the standard composition ratio, and then manually heated to become aluminum alloy liquid or molten state, and then poured into the aluminum bar mold cavity through the professional aluminum bar mold or the corresponding process, and finally cooled to form aluminum bars.
Production process of Aiboer Technology billets:
- Smelting
- Casting
- Sawdust
- Aluminum rod homogenization
- Refrigeration and rod washing
Forged aluminum bar
Aluminum forged bar is forged and formed by forging equipment, which requires a large amount of processing. However, the microstructure of forgings is relatively dense, and internal defects are not easy to occur. Therefore, aluminum forged bars are widely used for processing parts with high requirements, such as valve seats, valve cores, valve stems, etc.
Process flow of forged aluminum bar:
- blanking and heating
- Plastic deformation (continuous forging)
- subsequent processing
- quality inspection
- Packaging and delivery
Common alloy of forged aluminum bar: 2A01 2A02 2A10 2A11 2A12 3A21 3003 3004 3005 5A02 5A03 5A05 5B05 5A06 5050 5052 5056 5086 6A02 61016005 6063 6061 6082 7A04.
Temper: H112, T6, T652, T73, T735 etc.
Maximum diameter: 650mm
Application:
Aluminum forged bars are used in various industries, including aircraft, aerospace, automobile, construction, electrical appliances, military and national defense, marine, petrochemical and process equipment industries.
High strength weight ratio: for fuselage, car frame and panel, wheels.
Corrosion resistance: for fasteners, structural components and frames for building and decorative building elements, processing equipment and marine equipment.
Wear resistance and durability: for process equipment, fasteners and some motor parts.
Forging: generally refers to the solid deformation of metal materials under high temperature to reach the product shape.
Casting: after the metal material is melted, the liquid is poured into the mold cavity to reach the product shape;
Drawing (fine drawing) aluminum bar
Under the action of tensile force, the metal plastic forming method of aluminum alloy billets to obtain products with the same size and shape as the die hole by gradually reducing the cross-sectional area of the drawing die hole is called stretching. Drawing is widely used in the production of tubes, rods, shapes and wires. The drawing process of aluminum and aluminum alloy products is generally carried out at room temperature, so it is often called cold drawing.
Features of fine drawn aluminum bar:
- Precise size and smooth surface.
- Simple operation.
- The strength of aluminum bar can be improved due to cold work hardening.
- Fast stretching speed and high efficiency.
Classification according to the shape of aluminum bar
Round aluminum bar aluminum bars with circular cross section are called round aluminum bars. The common round aluminum bar is generally obtained by extrusion. Round aluminum bar is the most widely used aluminum bar. We can further process the aluminum bar according to customer needs, such as sawing, polishing, etc.
