Aluminum Round Bars
Aluminum round bars are widely used in various industrial applications due to their excellent corrosion resistance, especially in environments containing phosphoric, nitric, chloride, and sulfuric acids. The 6061 aluminum square rod is known for its ability to maintain structural integrity at extremely low temperatures, such as that of liquid nitrogen, making it ideal for cryogenic applications. Its high demand in the commercial market highlights its versatility and performance.
For applications requiring superior ductility, manufacturers can provide 6082 aluminum flat rods with low sulfur content, produced using advanced ladle refining techniques. In the molten state, a 5052 hexagonal aluminum rod is often exposed to vacuum to remove hydrogen, along with some oxygen and nitrogen, improving its purity and overall quality. The presence of tungsten and vanadium in 6063 aluminum rods helps form carbides, which enhance the hardness and stability of the final product. Additionally, elements like manganese, silicon, or aluminum are added during steelmaking in 7075 aluminum rods to eliminate dissolved oxygen, sulfur, and phosphorus from the melt.
Key Features of Aluminum Round Bars:
- High strength
- Corrosion resistance
- High pressure tolerance
- Heat resistance
- Dimensional stability
- Long service life
- Resistance to mechanical stress
Aluminum round bars are available in various grades including 6061, 6082, 5083, 5086, 5052, 6063, 7075, and 1100. They conform to international standards such as ASTM B221 / ASTM SB221, and are manufactured in dimensions following EN, DIN, JIS, ASTM, BS, ASME, and AISI specifications. The standard sizes range from 5mm to 500mm in diameter, with lengths extending from 100mm up to 3000mm or more. Surface finishes include black, bright polishing, rough turning, NO.4 Finish, Matt Finish, and BA Finish, offering flexibility for different applications.
