Aluminum 6061

5.0 (58 Reviews) 274 orders

Material type: Metal, Aluminum Alloy, Heat-Treatable, Medium-Strength, Weldable, Machinable, Corrosion-Resistant, Non-Magnetic

One of the most widely used aluminum alloys, cost-effective with good formability, weldability and machinability, offering moderate mechanical strength.

Process compatibility

CNC Milling CNC Turning

Material Color

Silver white

Material advantages

Excellent overall machinability, ideal for high-volume CNC machining and tight tolerance parts. Good weldability and formability, suitable for structural and fabricated components. Reliable corrosion resistance in most ambient environments. Heat-treatable to improve strength without losing too much ductility. Widely available and competitively priced, supporting fast lead times.

Material shortcomings

Lower strength compared to high-performance alloys like 7075, not suited for extreme load-bearing applications. Less formable than non-heat-treatable series such as 5052. May require post-machining finishing to achieve premium surface appearance.

Recommended description

6061 aluminum is the industry standard for general-purpose CNC machined parts. Balancing cost, machinability and performance, it works for structural components, brackets, fixtures, housings and everyday industrial parts that need consistent quality and cost efficiency.
