Custom Bronze Components
Custom Bronze CNC Machining
Bronze combines wear resistance, low-friction sliding behavior and corrosion resistance. Send your drawing for a grade, tolerance and production-route review with a clear custom machining quote.
Material Performance
Key Properties of Machined Bronze Alloys
Bronze properties vary widely with alloy family, product form and temper. These ranges cover common bearing, aluminum, nickel-aluminum and silicon bronzes.
Use the specified UNS grade and material condition for design. Final values must follow the applicable material certificate and standard.
Bronze Grade Selection
Common Bronze Alloys for CNC Parts
Choose the grade around load, sliding speed, lubrication, seawater exposure, strength and regulatory requirements.
C93200 Bearing Bronze / SAE 660
A high-leaded tin bronze with good machinability, low friction and anti-seizing behavior. Its strength is lower than aluminum bronze.
C95400 Aluminum Bronze
A high-strength cast aluminum bronze with strong wear and corrosion resistance for heavily loaded industrial and marine components.
C95500 Nickel Aluminum Bronze
A nickel-aluminum bronze combining high strength, wear resistance and marine-service stability.
C65500 High-Silicon Bronze
A wrought silicon bronze with corrosion resistance, useful strength, good formability and strong welding response.
C51000 Phosphor Bronze
A wrought phosphor bronze valued for spring response, fatigue resistance, wear performance and electrical-contact reliability.
C86300 Manganese Bronze
A high-strength cast copper alloy designed for heavy static loads, slow-speed sliding and robust structural bearing components.
Drawing-Based Capability
Bronze CNC Machining Parameters
Final capability is confirmed from the alloy, casting condition, wall thickness, geometry, tolerance and inspection method.
Control Tool Adhesion
Sharp tools and positive geometry reduce rubbing, smearing and built-up edge.
Match the Alloy
Bearing bronze and aluminum bronze require different speeds, feeds and tool strategies.
Protect Thin Walls
Light, distributed clamping limits distortion in bushings, sleeves and split components.
Verify Functional Bores
Bearing diameters, roundness and alignment are checked from the drawing datum system.
Machined Bronze Projects
Custom Bronze CNC Parts
Prototype, small-batch and repeat production for bushings, housings, fittings and precision mechanical components.
Bronze Post-Processing
Surface Finishes for Bronze Parts
Select the finish according to corrosion exposure, wear, friction and appearance requirements. Critical fits and bearing surfaces are protected during finishing.
Polishing & Brushing
Removes machining marks and creates a smooth satin or bright surface.
Bead Blasting
Produces a uniform matte texture and prepares the surface for coating.
Chemical Patina
Creates controlled brown, black or aged tones through a surface reaction.
Corrosion-Inhibiting Seal
BTA-based treatment with clear lacquer or wax limits tarnishing.
Metal Plating
Nickel, chrome, tin, silver or gold modifies protection, conductivity or appearance.
Quality Control
From Drawing Review to Final Inspection
Critical interfaces are identified before production and verified before approved parts are packed.
