Why should you choose machined bronze for your project?

Machined bronze is an excellent material choice for projects that require strength, durability, and resistance to corrosion and wear. It has a high bronze content, typically 80-90%, which gives it superior strength and wear resistance compared to other materials. Additionally, bronze has a low coefficient of friction, making it an ideal choice for bearings and other applications where smooth movement is critical. Bronze is also corrosion-resistant and can withstand exposure to water, chemicals, and other harsh conditions. Its ability to maintain its properties in extreme temperatures makes it a preferred material for industrial and aerospace applications. Choosing machined bronze for your project will provide a reliable and long-lasting component that can withstand the demands of heavy-duty applications.

Finishes for machined bronze

Machined bronze can be finished in various ways to achieve different surface appearances and properties. One option is a polished finish, which uses a polishing wheel or abrasive material to create a smooth, reflective surface. This finish can range from a low-luster satin finish to a mirror-like shine. For a more decorative look, bronze can also be plated with a thin layer of gold, silver, nickel, or other metals. This plating can provide improved corrosion resistance and distinctive color and shine. Finally,  bronze can be treated with various chemical finishes to change its color or create specific surface properties. Some common treatments include patination to make an aged or antique appearance and anodizing to create a durable, colorfast surface.
