6061 Aluminum Angle

Characteristics

The 6061 aluminum angle with equal leg length and rounded corners has an O temper, has an unpolished (mill) surface, meets American Society for Testing and Materials International ASTM B308 and SAE Aerospace Material Specifications AMS-QQ-A-200/8 standards, and has a standard tolerance. 6061 Aluminum Angle, aka Structural Aluminum Angle is an extruded aluminum product with inside radius corners that is intended for all structural applications where greater strength is required. Aluminum angle is available with square or rounded corners and with equal or unequal legs (the sides of the piece). The angles can be used for decorative applications to take advantage of the attractive finishes that are available, including satin clear, black, gold, brite clear and mill. The surface is easy to clean and polish, allowing the part to maintain its appearance over time. 6061 aluminum angle is a good general use alloy, containing magnesium and silicon as its major alloying elements. The 6061 aluminum alloy is a general-purpose material that combines good corrosion resistance, strength, machinability, and weldability. It resists stress corrosion cracking and is heat treatable. It is highly weldable and accepts applied coatings well. 

The 6061 aluminum has been annealed, a method of heating and cooling a material to modify its properties, such as increasing its formability and toughness or decreasing its strength, after it was shaped. The aluminum has a T6 temper, meaning it has been heat treated for increased strength. 6061 alloy is the accepted alloy for structural shapes and in the (-T6) condition the strength is approximately equal to that of structural steel.

• Mechanical Properties: Brinell = 95, Tensile = 45,000 +/-,  Yield = 40,000 +/-

Aluminum and aluminum alloys are lightweight compared to steel, brass, and copper, and have high strength-to-weight ratios. All series of aluminum alloys are nonmagnetic. Aluminum alloys have temper designations, indicating that the material has undergone a process to achieve certain properties of strength and hardness.

Features

• 6061 aluminum provides good corrosion resistance, strength, machinability, and weldability
• Meets ASTM B308 and AMS-QQ-A-200/8 specifications
• Unpolished (mill) surface has no finish
• Annealed to restore the material's original properties after shaping
• Heat treated for increased strength

Properties :

Tensile strength, used to indicate the material’s overall strength, is the peak stress it can withstand before it breaks. Corrosion resistance describes the material's ability to prevent deterioration caused by atmosphere, moisture, or other medium. Wear resistance indicates the ability to prevent surface damage caused by contact with other surfaces. Toughness describes the material's ability to absorb energy before breaking, while hardness (commonly measured as indentation hardness) describes its resistance to permanent surface deformation. Formability indicates how easily the material can be permanently shaped. Machinability describes how easily it can be cut, shaped, finished, or otherwise machined, while weldability characterizes the ability to be welded.6061-T6 angle comes in 25' lengths and has tapered legs.

Applications

6061 Aluminum Angle is widely used for all types of fabrication projects where lightweight and corrosion resistance is a concern. Used for general structural purposes. 6061 most widely used for scaffolding, ship construction, transmission towers, truck trailers, machine parts, and furniture applications. Used primarily for general structural applications, aluminum angles provide strength coupled with light weight. They are generally easy to weld, cut and machine. structural aluminum angles can be used for applications where a lightweight and corrosion resistant material is needed.
