Common Alloys and Specifications of CNC Machining Bronze
Bronze is an alloy that mainly contains copper and tin, also added certain amounts of aluminum and nickel. As another copper-based alloy, bronze is a little stronger than brass and more corrosion-resistant. Bronze is brittle and non-magnetic, excellent machinability, great electrical properties, low friction, and corrosion resistance to saltwater make it suitable for marine applications and parts that require withstand frictional contact. Types of bronzes include tine and phosphor bronze, silicon bronze, aluminum bronze, beryllium bronze, and high-tin bronze.
|Properties||Ductile, less brittle than cast iron, exhibits low friction, superior corrosion resistance, thermal and electrical conductivity|
|Applications (Bronze CNC Parts)||Bearings, bushings, screws, electrical connectors, springs, sculptures, medals, etc.|
|Wall Thickness||As low as 0.03” or determined by the ratio of wall thickness to planar dimension|
|Maximum Size||Determined by machines and complexity of the part|
|Tolerances||As low as 0.005” or determined by the alloy|
|Lead Time||As fast as 3 days, longer for complex custom bronze parts|
932 Bearing Bronze Composition and Properties
932 bronze, also known as SAE 660, C93200, and leaded tin bronze, is a high leaded tin bronze alloy that offers good strength and wear resistance, as well as excellent antifriction qualities, as the name implies, bronze grade 932 is typically used for bearings, bushings and washers.

Surface Finishing and Post Processing Options for Bronze Machining Parts
Bronze material naturally forms a layer of oxidation, unlike other metals, it does not often need a coating. There is a range of surface finishing and treatment methods suitable for CNC machining bronze parts provided at CNCJY.
Bronze CNC Machining FAQs
What is CNC Bronze Machining?
Is Bronze Good for CNC Machining?
Soft metals offer various advantageous characteristics for CNC machined components. They are often easy to process, naturally resistant to corrosion, and excellent for a wide range of industrial applications, particularly brass and bronze.
Due to bronze’s excellent machinability, engineers and designers should be aware that bronze’s mechanical and physical properties change when phosphorus, aluminum, manganese, and silicon are added. 642 bronze has the highest machinability out of all brass and bronze alloys, it is renowned for its high tensile strength, ductility, thermal conductivity, hardness, low friction, and corrosion resistance. 932 bronze is also a preferred option by machining companies.
What’s the Difference Between Bronze and Brass
Copper and zinc are the primary elements of brass. Brass composed of copper and zinc is called ordinary brass. If it is a variety of alloys composed of more than two elements, it is called special brass. Bronze is a copper alloy with tin as the main additive, sometimes adding other elements such as phosphorus, manganese, aluminum, or silicon.
Brass is more malleable than either zinc or copper. Low melting point and flows when molten. Brass is resistant to corrosion due to the presence of iron, aluminum, silicon, and manganese in its composition. Ammonia makes a material vulnerable to cracking under tension. Not as hard as steel. Bronze is a brittle, hard metal, that resists corrosion, especially from seawater, and fatigue better than steel and conducts heat and electricity better than most steels.
