Aluminum solid rivets are a versatile and commonly used type of fastener in various industrial applications. They offer excellent strength, corrosion resistance, and ease of installation. Choosing the right size and type of aluminum solid rivets is crucial to ensure proper performance and safety.

Material and Strength

Aluminum solid rivets are available in various alloys, each offering specific strength characteristics. The most commonly used alloys include 2017-T4 (standard strength), 2117-T4 (high strength), and 7050-T6 (aerospace grade). The strength requirement of the application will determine the appropriate alloy.

Diameter and Length

The diameter of the rivet refers to the thickness of the material it is designed to join. The length of the rivet is measured from the top of the head to the end of the shank. Both the diameter and length should be carefully selected to ensure sufficient strength and avoid overstressing or splitting the material.

Head Style and Grip Range

The head style of a rivet refers to the shape of its head. Common head styles include flat, countersunk, and button. The grip range specifies the thickness of the material that the rivet can accommodate. The head style and grip range should be chosen based on the application and the space available.

Drive Type

Aluminum solid rivets can be installed using various drive types, including hand rivets, rivet guns, and robotic riveters. The drive type should be compatible with the rivet design and the available equipment.

Corrosion Resistance

Aluminum is naturally corrosion-resistant, making it suitable for use in harsh environments. However, some applications may require additional corrosion protection. Anodized rivets provide increased corrosion resistance and can be used in marine or chemical environments.

Considerations for Specific Applications

Choosing the right type of rivet also depends on specific applications:

Aerospace: High-strength 7050-T6 rivets are commonly used in aerospace applications where weight and strength are critical.

Automotive: Standard strength 2017-T4 rivets are suitable for automotive applications, such as body panels and chassis components.

Construction: High-strength 2117-T4 rivets are often used in construction projects where load-bearing connections are required.

Conclusion

Choosing the right size and type of aluminum solid rivets is essential for ensuring the proper performance and safety of the application. By considering the material, strength, diameter, length, head style, grip range, drive type, corrosion resistance, and specific application requirements, engineers and technicians can select the most appropriate rivets for their projects.
