Categorizing Aluminum Bars Based on Processing Techniques

1. Extruded Aluminum Bar

The extrusion process is widely utilized in the manufacturing of aluminum bars. It involves shaping and pushing aluminum bars onto metal materials at a specific temperature, taking advantage of the raw material's excellent plasticity.

The following is the flow of the production process for extruded aluminum bars:

• Preparation for extrusion;

• Extrusion;

• Stretching and Straightening;

• Sawing finished products, trimming, and framing.

The following are common types of extruded aluminum bar alloys: 1050, 1060, 2011, 2014, 2017, 2024, 2618, 5052, 5083, 5086, 5454, 5754, 6061, 6063, 6082, 7003, 7022, 7050, 7055, and 7075.

2. Casting aluminum bar

The production process of the casting aluminum bar consists of several steps. Initially, pure aluminum or aluminum alloy ingots are prepared in accordance with the specified composition ratio. Subsequently, they are heated manually until they reach a molten state, transforming into aluminum alloy liquid. Then, this liquid is poured into an aluminum bar mold cavity using either a professional aluminum bar mold or an appropriate procedure. Lastly, the mixture is allowed to cool down, resulting in the formation of solid aluminum bars.

The manufacturing procedure for Linsy aluminum billets:

• Smelting

• Casting

• Sawdust

• Homogenization of aluminum rods

• Refrigeration and cleaning of rods

3. Forged aluminum bar

The process of forging aluminum bars involves the use of forging equipment, which requires extensive processing. Nevertheless, the forgings have a dense microstructure and are less prone to internal defects. As a result, aluminum forged bars are extensively utilized in the manufacturing of components that demand high precision, such as valve seats, valve cores, and valve stems.

The following outlines the steps involved in the production of forged aluminum bars:

• blanking and heating

• Plastic deformation (continuous forging)

• subsequent processing

• quality inspection

• Packaging and delivery

The following are common alloys of forged aluminum bar: 2A01, 2A02, 2A10, 2A11, 2A12, 3A21, 3003, 3004, 3005, 5A02, 5A03, 5A05, 5B05, 5A06, 5050, 5052, 5056, 5086, 6A02, 6101, 6005, 6063, 6061, and 6082.

Temper: H112, T6, T652, T73, T735

Maximum diameter: 650mm

Application:

Aluminum forged bars find application in a wide range of industries such as aircraft, aerospace, automotive, construction, electrical appliances, military and national defense, marine, petrochemical, and process equipment.

The high strength-to-weight ratio is beneficial for various applications such as the fuselage, car frame, panel, and wheels.

Corrosion resistance is essential for various applications, including fasteners, structural components, building frames, decorative building elements, processing equipment, and marine equipment.

Wear resistance and durability are essential qualities for process equipment, fasteners, and certain motor components.

Forging is a term that typically describes the process of shaping metal materials through solid deformation at high temperatures in order to achieve the desired product shape.

Casting involves pouring the melted metal material into the mold cavity in order to achieve the desired shape of the final product.

4. Fine drawing aluminum bar

Stretching is the metal-plastic forming method of aluminum alloy billets that involves applying a tensile force to gradually reduce the cross-sectional area of the drawing die hole, resulting in products with the same size and shape as the die hole. This process, also known as drawing, is extensively utilized in the production of tubes, rods, shapes, and wires. Since the drawing process for aluminum and aluminum alloy products typically occurs at room temperature, it is commonly referred to as cold drawing.

Fine-drawn aluminum bar features:

• Accurate dimensions and polished exterior.

• Simple operation.

• Cold work hardening can enhance the strength of aluminum bars.

• Quick stretching speed and high efficiency.
