The All-Around Performer

Aluminum's versatility stems from its unique combination of properties, which can be further optimized by alloying it with other elements like copper, zinc, or magnesium.

High Strength-to-Weight

Aluminum offers excellent structural integrity for its low density, making it ideal for aerospace, automotive, and portable electronics.

Corrosion Resistance

It naturally forms a thin, protective oxide layer that prevents further corrosion in most atmospheric and freshwater environments.

Excellent Thermal Conductivity

Aluminum is a great conductor of heat, making it a top choice for heat sinks and other thermal management components.

Common Aluminum Alloys

6061-T6 Aluminum

The most widely used and versatile aluminum alloy. It offers a good balance of strength, excellent machinability, and good weldability. It's the go-to choice for general-purpose structural components, frames, and consumer product enclosures. Available in sheet, plate, and bar stock.

7075-T6 Aluminum

A very high-strength aluminum alloy, comparable to many steels. It is significantly stronger than 6061 and is used in high-stress applications where maximum strength is required, such as aerospace components, competitive robotics, and heavy-duty industrial parts. It is less machinable and weldable than 6061.

5052-H32 Aluminum

Primarily a sheet alloy known for its excellent formability and very good corrosion resistance, especially in marine and saltwater environments. It is often used for sheet metal enclosures, brackets, and fuel tanks where bending and forming are primary manufacturing operations.

Aluminum Alloys FAQ

What is the "T6" in 6061-T6?

The "T6" designation refers to a specific heat treatment process. For 6061, T6 means the alloy has been solution heat-treated and artificially aged. This process significantly increases the aluminum's strength and hardness, making it suitable for structural applications.

Can aluminum be welded?

Yes, many aluminum alloys can be welded, most commonly using TIG or MIG welding processes. However, certain high-strength alloys like 7075 are considered non-weldable or very difficult to weld due to their tendency to crack during the welding process.
