Tin Bronze
Known for its excellent corrosion resistance and wear properties, tin bronze is widely used in bearings, bushings, and marine hardware. It typically contains about 12% tin, providing a balance of ductility and strength. This alloy is suitable for applications where resistance to fatigue, shock, and abrasion is essential.
Aluminum Bronze
Containing about 5-11% aluminum, this type offers high strength and excellent corrosion resistance, especially in marine environments. It's used in applications like aircraft parts, marine hardware, and pump components. Aluminum bronze also exhibits good wear resistance and can handle heavy loads.
Silicon Bronze
With a higher silicon content, this bronze variant is known for its good corrosion resistance, making it ideal for outdoor applications like architecture, art, and marine fittings. Silicon bronze is easy to weld and form, offering a combination of strength and ductility.
Phosphor Bronze
Phosphor bronze contains around 0.5-11% tin and a small amount of phosphorus. It's known for its fine grain, high fatigue resistance, and excellent formability. Common uses include electrical connectors, springs, and various types of industrial bearings.
Nickel Bronze
This alloy, enriched with nickel, offers enhanced strength and corrosion resistance. It’s commonly used in decorative applications for its appealing silver color, and in functional components such as valves, pump parts, and ship propellers that require durability in corrosive environments.
Leaded Bronze
Incorporating lead into bronze improves machinability and wear resistance, making it suitable for bearings, bushings, and similar components subject to high-speed and heavy-load applications. Leaded bronze also offers good corrosion resistance and is often used in plumbing and pipe fittings.
