Anucha Metals, one of the trusted manufacturers and suppliers located in Bangkok, Thailand, provides premium-grade Aluminium Round Bars and Rods suitable for various industrial and commercial uses. The round bars are produced from top-quality aluminium alloys like 6061, 6082, 7075, and 2024, which provide superior strength-to-weight ratio, corrosion resistance, and machinability. Manufactured according to ASTM B211 and international specifications, our round bars come in different tempers and sizes. For structural framework, machining parts, or fittings for the aerospace industry, Anucha Metals guarantees accuracy, uniformity, and quality in each supplied aluminium round bar.
Aluminium round bars generally consist of aluminium (90–98%) along with alloying components like magnesium, silicon, zinc, copper, or manganese, depending on the grade. For instance, 6061-T6 bars provide tensile strength in the range 310 MPa, yield strength 275 MPa, and a high degree of fatigue resistance. Alloys such as 7075 have tensile strength up to 570 MPa. These bars possess light weight characteristics, good corrosion resistance, and are easily weldable and machinable, depending on the alloy and temper.

Aluminium round bars find extensive applications in the aerospace, automotive, marine, and construction industries. They are used in shafts, bolts, rivets, spacers, and structural supports. In machinery and tooling, they’re employed for pins, valves, connectors, and cylinders. In aerospace and defense, light and high-strength alloys such as 2024 and 7075 are employed for airframe parts and fasteners. In building design, they find use in handrails, frames, and ornamental hardware. The shape of the bars makes machining easy into complex shapes, thus ideal for high-volume production and custom-engineered pieces.
