Aluminum angle 6061 is a type of aluminum extrusion that has an L-shaped cross-section, with two legs that form a 90-degree angle. It is made from the 6061 alloy, which is a heat-treatable aluminum alloy that belongs to the 6xxx series of aluminum alloys. The 6061 alloy is primarily composed of aluminum (Al), with small amounts of magnesium (Mg), silicon (Si), and other elements as alloying elements.

Here are some key properties of aluminum angle 6061:

1. High strength: Aluminum 6061 angle has excellent strength, with a tensile strength of around 275 MPa (40 ksi) and a yield strength of approximately 240 MPa (35 ksi) in the T6 temper, which is the most commonly used temper for this alloy.
2. Good machinability: Aluminum 6061 angle has good machinability, making it suitable for a wide range of machining operations, such as milling, drilling, turning, and tapping.
3. Heat treatability: Aluminum 6061 angle is heat-treatable, allowing for improved mechanical properties and increased strength through a process called precipitation hardening. This makes it suitable for applications that require higher strength levels.
4. Excellent corrosion resistance: Aluminum 6061 angle has good resistance to corrosion in various environments, making it suitable for outdoor and other corrosive environments.
5. Versatility: Aluminum angle 6061 is used in a wide range of applications, including structural applications in construction, aerospace components, marine structures, automotive parts, machinery components, and architectural applications, among others.
6. Lightweight: Aluminum 6061 angle has a low density, which makes it lightweight compared to many other metals. This makes it suitable for applications where weight reduction is desired, such as in aerospace, automotive, and transportation industries.
7. Easy to join: Aluminum 6061 angle can be easily joined using various methods, including welding, brazing, and mechanical fastening.

It’s important to note that specific properties and characteristics of aluminum angle 6061 may vary depending on the temper, size, and thickness of the angle. Therefore, it’s always recommended to consult the relevant specifications and standards for your specific application requirements, and work with a reputable supplier to ensure that the aluminum angle meets your intended application needs.
