Copper CNC Machining Services
Copper CNC machining is a way to make parts from copper using computer-controlled tools. At Istar Machining, we use high-tech machines to cut, shape, and finish copper into exactly what you need. Our machines follow computer instructions to make perfect parts every time.
Copper is a soft, reddish-brown metal that works great for many jobs. It’s one of the best metals for moving heat and electricity, which is why it’s used in so many important things. From simple parts to complex shapes, we can make exactly what you need with our advanced CNC (Computer Numerical Control) tools.

Why Choose Copper for Your Parts?
Copper has some special powers that make it perfect for many jobs:
- Amazing electricity conductor – moves electricity better than almost any other metal
- Great heat mover – pulls heat away quickly (that’s why it’s used in cooking pots!)
- Fights germs – naturally kills bacteria and viruses
- Won’t rust – stands up to water and weather
- Easy to work with – can be shaped in many ways
- Looks nice – has a warm, attractive color
At Istar Machining, we work with several grades of copper, including C101, C110, and C360. Each type has special qualities for different jobs. We’ll help you pick the right one for your project.

Our Copper CNC Capabilities
Our shop has the most advanced equipment to work with copper in many ways. Here’s what we can do:
Machining Process | What We Can Do | Benefits |
5-axis milling | Complex 3D shapes with undercuts | Perfect for intricate parts like waveguides |
CNC turning | Round parts with tight tolerances | Ideal for bushings, connectors, fittings |
EDM machining | Ultra-precise cuts and shapes | Great for small, detailed components |
Surface finishing | Polishing, plating, annealing | Enhanced performance and appearance |
Precision tolerances | Down to ±0.001″ (0.025mm) | Ensures perfect fit and function |
Surface finishes | 8-32 µin Ra | From mirror smooth to textured as needed |
Need both milling and turning? Check out our multi-axis turning capabilities for complex parts that need both cutting methods.
Maximum Part Size
We can make copper parts up to 300mm x 300mm x 150mm (about 12″ x 12″ x 6″).
Speed of Service
- Prototypes: As fast as 24 hours
- Production runs: 5-10 days depending on complexity
- Rush service: Available when you’re in a hurry
For extremely precise work, our sinker EDM machining is perfect for copper parts that need super sharp corners or tiny details.
Industries We Serve with Copper CNC Parts
Copper parts are used in many important industries. Here are some ways our customers use our copper machining services:
Copper Grades We Work With
At Istar Machining, we use different types of copper depending on what you need:
C101 (Oxygen-Free Copper)
- Best for: Electrical components requiring maximum conductivity
- Properties: 100% conductivity, very pure
- Common uses: High-end electrical connectors, PCB components
C110 (ETP Copper)
- Best for: General electrical and thermal applications
- Properties: 98% conductivity, good machinability
- Common uses: Heat sinks, electrical bus bars, plumbing fittings
C360 (Free-Cutting Brass)
- Best for: Complex parts requiring better machinability
- Properties: 60-63% copper, 3% lead, easier to machine
- Common uses: Valves, fittings, gears, decorative hardware
For applications that need both copper’s properties and better machinability, check out our brass CNC machining services.

Frequently Asked Question
C101 (Oxygen-Free Copper) is ideal for electrical applications requiring maximum conductivity. It’s 99.99% pure copper with no oxygen content.
Yes! Our 5-axis machines and EDM capabilities allow us to create very complex shapes with tight tolerances. We can produce sharp corners, thin walls, and intricate details in copper.
We can deliver simple prototypes in as fast as 24 hours. More complex parts typically take 3-5 days. Production runs usually require 5-10 days depending on quantity and complexity.
While copper material costs more than some metals, its excellent machinability often means lower overall production costs. We’ll help you optimize your design to keep costs down.
Absolutely! Copper naturally develops a protective patina outdoors that actually enhances its corrosion resistance. It’s excellent for outdoor applications.
