Characteristics of aluminum-iron cap open rivet and its selection principle
Nov 29, 2018

Compared with ordinary blind rivets, the aluminum-iron cap open rivet has a significantly larger diameter of the aluminum cap. The rivet has a larger contact area when riveted with the connecting piece, and has a stronger supporting surface to enhance the torque strength. Can withstand higher radial pull. With its unique properties, the aluminum-iron cap open rivet is suitable for fastening soft, fragile surface materials and extra-large holes, adding a brim diameter for special protection of soft materials.

When selecting aluminum-iron cap open rivets, inspections are required, including riveting diameter, rivet rod length, rivet cap thickness and cap diameter, total core length, nail core exposed size, nail cap size, and after assembly. The outer diameter can be considered. In the actual inspection, the weak parts of the product can be measured, such as tensile strength, shear resistance, and nail core prevention.

In addition, the total thickness of the workpiece is generally 45% - 65% of the length of the aluminum-iron cap open rivet, preferably not more than 60%. The recommendation is usually 50%--60%. The length of the rivet is too long, the rivet head is too large, and the shank is easy to bend; if the length of the rivet is too short, the thickness of the shank is insufficient, the forming of the nail head is incomplete, and the strength and compactness are affected. The length of the rivet is too long or too short, and only the proper length can achieve the best riveting effect.
