Gunmetal bushings have a low coefficient of friction, which means they can reduce friction and wear between moving parts. This property is crucial for ensuring smooth and efficient operation, especially in high-load or high-speed applications.

The inclusion of tin in gunmetal enhances its resistance to corrosion, making gunmetal bushings suitable for use in environments where exposure to moisture or harsh chemicals is a concern. This property is particularly beneficial in marine and other outdoor applications.

Gunmetal bushings exhibit high mechanical strength, providing excellent support and load-bearing capabilities. They can withstand heavy loads and provide stability to the moving parts they support.
