Shim brass is a specific type of brass material used for making shims—pieces of material used to fill gaps, provide support, or achieve alignment, depending on the application. It is typically made from a copper-zinc alloy, providing strength, malleability, and corrosion resistance. They are available in various thicknesses and can be cut into custom shapes and sizes to meet specific application requirements. Because brass has a relatively low friction rate, shim brass is suitable for applications where sliding or movement occurs without causing wear or damage.
