Key Features of Aluminum Round Bar
Aluminum round bar offers a well-balanced set of properties that make it suitable for diverse industrial and commercial applications:
– **Lightweight:** Aluminum’s low density (approximately 2.7 g/cm³) makes aluminum round bar significantly lighter than steel or copper bar of equivalent size, reducing component weight and handling costs.
– **Good Mechanical Strength:** Depending on alloy and temper, tensile strength ranges from 70 MPa for pure aluminum to over 570 MPa for 7075-T6, covering a wide range of structural requirements.
– **Excellent Corrosion Resistance:** Most aluminum alloys form a natural oxide layer that provides effective protection in atmospheric and mildly corrosive environments.
– **Outstanding Machinability:** Aluminum round bar is easy to machine, drill, mill, and turn, with 2011 and 6061 grades being particularly well suited for high-speed CNC machining.
– **Good Weldability:** 6000 and 1000 series alloys offer good weldability for fabricated structures and assemblies.
– **Good Electrical and Thermal Conductivity:** 1000 series aluminum round bar offers high conductivity suitable for electrical and heat transfer applications.
– **Anodizable Surface:** Aluminum round bar can be anodized for improved surface hardness, corrosion protection, and decorative finish.
– **Wide Alloy and Temper Range:** Available in 1060, 2011, 2024, 6061, 6063, 6082, 7075, and other alloys in various tempers including T4, T5, T6, T651, H112, and O.

What is the difference between 6061 and 7075 aluminum round bar?
6061 is a general-purpose alloy offering good strength, excellent corrosion resistance, good weldability, and outstanding machinability in T6 temper. 7075 is a high-strength alloy with tensile strength exceeding 500 MPa in T6 temper, used for aerospace, defense, and highly stressed structural components. 7075 has lower corrosion resistance and weldability than 6061 but offers significantly higher strength.
What diameters are available for aluminum round bar?
We supply aluminum round bar from 3mm small diameter precision rod up to 500mm large diameter bar, depending on the alloy grade. Standard diameters are available from stock, and custom sizes can be produced on request based on quantity requirements.
Can aluminum round bar be supplied cut to custom lengths?
Yes. We offer cutting to length services with standard lengths from 1000mm to 6000mm and custom lengths available on request. Precision saw-cut ends and specific length tolerances can be arranged for machining applications.
Which aluminum round bar grade is best for CNC machining?
6061-T6 is the most commonly used grade for general CNC machining due to its excellent machinability, good mechanical properties, and dimensional stability. 2011 aluminum is specifically formulated for high-speed machining with the best chip-breaking performance. 7075-T651 is preferred when maximum strength is required in precision machined components.
