When you need high-quality, precision-machined brass or copper components, CNC turning and milling deliver unbeatable accuracy and repeatability. Whether you're an engineer designing custom fittings or an OEM manufacturer sourcing durable metal parts, understanding how CNC machining works with brass and copper can help you get the best results—without the headaches.
Why Choose CNC Machining for Brass & Copper Parts?
Brass and copper aren’t just pretty metals—they’re functional, conductive, and corrosion-resistant, making them ideal for industries like plumbing, electronics, and automotive. Here’s why CNC machining is the best way to shape them:
✔ Tight Tolerances (±0.01mm achievable) – Perfect for精密 fittings and connectors
✔ Smooth Finishes (No burrs, no rough edges) – Critical for密封 and electrical contacts
✔ Fast Turnaround (No tooling delays) – Get prototypes or production parts in days
✔ Complex Geometries (Threads, slots,precise grooves) – CNC handles what manual machining can’t
Industries That Rely on Machined Brass & Copper:
- Electronics (Connectors, terminals, heat sinks)
- Plumbing & HVAC (Valves, fittings, nozzles)
- Automotive (Bushings, fuel system components)
- Marine (Corrosion-resistant fasteners and fittings)
Brass vs. Copper: Which Should You Use?
| Material | Key Properties | Best For |
| Brass (C360) | Easy to machine, excellent corrosion resistance | Fittings, gears, decorative parts |
| Free-Cutting Brass | Even smoother machining, minimal tool wear | High-volume turned parts |
| Copper (C110) | Superior conductivity, antimicrobial | Electrical components, heat exchangers |
| Beryllium Copper | High strength, spring-like properties | Aerospace connectors, industrial springs |
CNC Turning vs. Milling for Brass & Copper
CNC Turning (Best for Cylindrical Parts)
✔ Ideal for: Bushings, nozzles, threaded rods
✔ Advantages: Faster production, better surface finish on round parts
✔ Limitations: Less flexible for complex 3D shapes
CNC Milling (Best for Complex Shapes)
✔ Ideal for: Brackets, enclosures, custom connectors
✔ Advantages: Handles intricate contours and pockets
✔ Limitations: Slightly slower for simple round parts
Hybrid Approach? Our factory combines turning and milling to achieve maximum efficiency.
Key Benefits of CNC for OEM Brass & Copper Parts
- No MOQ (Minimum Order Quantity) – Order 1 prototype or 10,000+ production parts
- Consistent Quality – Every part matches the CAD model exactly
- Wide Material Options – From standard brass to specialty alloys
- Fast Lead Times – No waiting for custom molds or tooling
Final Thoughts
Brass and copper parts might seem simple, but precision matters—especially in electrical, fluid, and mechanical systems. CNC turning and milling ensure your components fit perfectly, perform reliably, and look professional.
