What is bronze?
Bronze is a mixture of copper, approximately 35% tin, and 8% lead. It is a high-performance copper-based alloy, primarily composed of copper (Cu) and tin (Sn), with optional additions of alloying elements such as aluminum, silicon, phosphorus, manganese, zinc, nickel, or iron to enhance its mechanical strength, corrosion resistance, wear resistance, and machinability, achieving a machinability index of up to 100%. This material’s mechanical properties make it ideal for manufacturing low-stress components, providing reliable performance and a long service life even in harsh applications.
Bronze Material Properties
Bronze alloys vary in composition, typically being alloys of copper with tin, aluminum, zinc, or phosphorus, allowing their properties to be tailored to specific requirements. The properties of bronze make it ideal for parts that combine mechanical strength and environmental adaptability. Common characteristics include:
- Density: 7.4–8.9 g/cm³, providing a lightweight yet robust structure.
- Hardness: Rockwell B 55–100, offering wear resistance without excessive brittleness.
- Tensile Strength: 18,000–100,000 PSI, depending on grade.
- Elongation: 10–15%, ensuring ductility for forming complex shapes.
- Maximum Service Temperature: Up to 1,800°F in select alloys.

FAQ
Yes, bronze is generally easy to machine due to its high machinability, especially alloys like C93200 bearing bronze. At Elimold, we optimize cutting speeds and feed rates for smooth cuts, reduced tool wear, and excellent surface finishes.
Yes, bronze is generally easier to machine than most steels due to its lower hardness, better thermal conductivity, and easier chip formation control, resulting in increased production speeds and extended tool life. This makes it ideal for Elimold's high-volume production.
Yes, bronze has excellent corrosion resistance, especially in salt water, making it an excellent choice for marine components such as propellers and fittings.
Yes, some bronze alloys, such as C51000, are used to manufacture electrical connectors due to their good electrical conductivity and corrosion resistance.
While both materials can be machined, brass is easier to machine due to its lower hardness. Bronze is more durable and better suited for parts that need to withstand wear.
Our bronze CNC machining capabilities typically achieve tolerances of ±0.0001 inches for small features and ±0.005 inches for large parts. Specific tolerances depend on various factors, including part size, geometry, bronze alloy, and machining process. For critical applications with even higher tolerance requirements, we can often achieve accuracy of ±0.00005 inches through special processes.
The lead time for bronze CNC machining projects depends on the complexity of the parts, the quantity, and the current workload. For simple prototypes, we can typically deliver within 3-5 business days. Mass production typically takes 2-4 weeks, depending on the production volume. We also offer expedited services to meet urgent project needs. We recommend that you contact us with your specific requirements so that we can provide you with a more accurate delivery time.
Yes, our factory is fully equipped to process large bronze parts up to 48 inches × 36 inches × 30 inches. We have a variety of CNC machine tools, including large vertical and horizontal machining centers, enabling precision machining of large bronze parts. Our expertise lies in addressing the unique challenges of machining large bronze parts, such as material handling, thermal control, and maintaining tight tolerances on large surfaces.
Yes. Bronze itself is corrosion-resistant and can be machined with minor surface treatments. Surface treatments such as electroplating and painting can further enhance its corrosion resistance, conductivity, and aesthetics. Additionally, embedding graphite lubricant into bronze creates self-lubricating bronze, effectively reducing friction.
- Optimize material utilization: Use nesting software for efficient part layout, minimizing waste and recycling waste to reduce costs.
- Simplify process flow: For surfaces with low decorative requirements and non-critical surfaces, use a "machine blank surface" process. Integrate features into a single toolpath to shorten machining cycles.
- Batch production planning: For small batch orders (10-50 pieces), allocate setup time across multiple parts. For large batch orders (>100 pieces), use high-speed CNC machine tools to improve efficiency and reduce unit labor costs.
