Yes, brass rivets can be used in wood. In fact, they are a common and often preferred choice for certain woodworking applications due to their beneficial properties.
Here's why brass rivets are suitable for wood:
Advantages of using brass rivets in wood:
Aesthetic Appeal: Brass has a naturally warm, golden color that can add a decorative touch to wooden projects. It can also develop a nice patina over time.
Corrosion Resistance: Brass is an alloy of copper and zinc, both of which offer good resistance to corrosion. This is beneficial in environments where the wood might be exposed to moisture.
Strength: Brass rivets provide a strong and permanent fastening solution for wood, similar to how they function in other materials like leather and metal.
Ease of Installation: Like other rivets, brass rivets can be installed relatively easily with the appropriate tools (e.g., rivet gun or hammer and setter).
Joining Dissimilar Materials: Rivets, including brass ones, are suitable for joining wood to other materials like metal or leather.
Vibration Resistance: Riveted joints are generally resistant to loosening due to vibration, which can be an advantage in certain wooden structures or items.

Considerations when using brass rivets in wood:
Softness of Brass: Compared to steel, brass is a softer metal. In applications with very high stress or abrasive wear, this might be a factor to consider, although it's usually sufficient for most woodworking needs.
Washer Use: When using rivets in softer materials like wood, it's often recommended to use washers (burrs) on the back side to prevent the rivet head from pulling through the wood, especially under stress.
Pilot Holes: Drilling pilot holes slightly smaller than the rivet shank is generally necessary to ensure proper setting and prevent the wood from splitting.
Type of Rivet: Different types of rivets exist (e.g., solid, tubular, split). The best type for a woodworking project will depend on the specific application and the thickness of the wood being joined. Split rivets, for example, are often used for softer materials like wood and leather.
In summary, brass rivets are a viable and often attractive and functional option for joining wood in various woodworking projects. They offer a good combination of strength, corrosion resistance, and aesthetic appeal. Just be sure to use appropriate techniques and consider the specific demands of your project.
