Which of the following is NOT a characteristic of repairs made using aluminum rivets?

The correct answer highlights that aluminum rivets are not inherently difficult to install. In fact, one of the advantages of using aluminum rivets is their relative ease of installation, especially when compared to other fastening methods. This ease of use makes them a popular choice in both industrial and construction applications.

When using aluminum rivets, the installation process typically involves drilling a hole, inserting the rivet, and then using a specialized tool to set the rivet in place. This method is straightforward and can often be done effectively with minimal training.

In contrast, the other characteristics listed all describe aspects of aluminum rivets accurately. They are designed to withstand high stress, making them suitable for a variety of applications where strength is critical. Additionally, they require specific hole sizes to ensure a proper fit, which is important for maintaining the integrity of the structure being repaired. Lastly, aluminum rivets are lightweight, contributing to the overall weight savings in construction and repair applications where minimizing weight is beneficial.

This understanding of the properties of aluminum rivets helps clarify their ideal uses and advantages in practical applications.
