Definition and Uses

Aluminum round bars are elongated materials made from aluminum, widely used in various fields including, but not limited to, mechanical manufacturing, aerospace, and architectural decoration. Their main uses include the production of various mechanical parts, building components, and various forms of machining such as turning, drilling, and cutting.

Classification and Characteristics

Different Series of Aluminum Round Bars:

1. 1000 Series Aluminum Bars: Examples include 1050, 1060, and 1100 series. They have a lower production cost due to the presence of other elements, making them relatively inexpensive.

2. 2000 Series Aluminum Bars: Represented by 2A16 (LY16) and 2A02 (LY6), these bars have a higher hardness and are primarily used in aircraft structures and rivets.

3. 3000 Series Aluminum Bars: Mainly composed of manganese, they offer good rust resistance.

4. 4000 Series Aluminum Bars: With a higher silicon content, these are commonly used in construction and mechanical parts.

5. 5000 Series Aluminum Bars: Examples include 5052 and 5083, which are widely used due to their low density and high tensile strength.

6. 6000 Series Aluminum Bars: Represented by 6061 and 6063, these bars contain magnesium and silicon, combining the advantages of the 4000 and 5000 series.

7. 7000 Series Aluminum Bars: Represented by 7075, these bars contain zinc and are classified as aerospace materials, characterized by ultra-high strength aluminum alloys.

8. 8000 Series Aluminum Bars: Commonly, 8011 is used, primarily for aluminum foil production.

Material and Specifications

Aluminum round bars come in various materials, including pure aluminum, hard aluminum, rust-resistant aluminum, aluminum-magnesium alloys, and aluminum-silicon alloys. Common specifications range from Φ6mm to Φ500mm, and can be customized according to requirements.

Production Process

The production of aluminum round bars mainly involves three steps: melting, casting, and extrusion. During the melting process, impurities and gases need to be removed. Casting involves cooling the melted aluminum to form shapes, and finally, extrusion is used to enhance the strength of the material.

Market Supply Situation

Currently, there are numerous suppliers of aluminum round bars in the market, including well-known domestic and international companies. These suppliers offer a wide variety of aluminum round bars with complete specifications to meet different customer needs.

Application Fields

Due to their excellent properties, aluminum round bars have a wide range of applications. For example, in mechanical manufacturing, they can be used to produce various mechanical parts; in aerospace, their lightweight and high-strength characteristics make them suitable for aircraft structural components; in architectural decoration, they can be used to create doors, windows, railings, and more.
