Why Choose Copper for Your Parts?
Copper has some amazing qualities that make it perfect for many jobs:
- Conducts electricity really well – Great for electrical parts
- Moves heat quickly – Perfect for cooling systems
- Doesn’t rust easily – Lasts a long time outdoors
- Kills germs – Good for medical tools
- Looks nice – Has a warm, pretty color
At Istar Machining, we work with many types of copper to fit your needs perfectly.
Types of Copper We Work With
We use different kinds of copper based on what your part needs to do:
Copper Type | Best Uses | Special Features |
C101/C110 (Pure Copper) | Electrical wires, Heat sinks | Best conductor of electricity and heat |
C145 (Tellurium Copper) | Precision parts, Fittings | Easier to machine, better surface finish |
C172 (Beryllium Copper) | Springs, Tools | Very strong, won’t create sparks |
Brass (Copper-Zinc) | Decorative parts, Boat fittings | Resists salt water damage |
Bronze | Bearings, Industrial parts | Handles wear and tear very well |
Our team at Istar Machining will help you pick the right type for your project.
How We Make Your Copper Parts
Our precision CNC machining process follows these steps to make perfect copper parts:
- Design Review – We look at your drawings or 3D files

Technical Details You Should Know
When planning your copper parts, here are some important things to know: [^3]
Parameter | What We Can Do | Why It Matters |
Tolerances | As tight as ±0.001″ (0.025mm) | Ensures parts fit perfectly together |
Surface Finish | Ra 8–32 µin | Smoother surfaces conduct better |
Max Part Size | 24″ x 12″ x 12″ | Lets us make both small and big parts |
Wall Thickness | As thin as 0.02″ | Important for heat transfer |
Hole Sizes | As small as 0.04″ | Needed for mounting or fluid flow |

Common Uses for Our Copper Parts
Our copper parts are used in many different industries:
Green Energy Systems
Solar panel connectors, wind turbine wiring, and battery terminals need copper’s excellent conductivity.
Medical Equipment
Copper’s germ-killing properties make it perfect for medical CNC machining of tools and equipment parts.
Electronics
Computers, phones, and other devices need copper heat sinks to stay cool and work properly.
Plumbing
Water systems use copper parts because they’re safe for drinking water and last a long time.
Surface Finishes for Copper Parts
We offer different ways to finish your copper parts:
- Raw Machined – Best for electrical conductivity
- Polished – Smooth and shiny for a nice look
- Brushed – Modern, professional appearance
- Plated – Add nickel or other metals for special properties
- Anodized – Colored coating for decoration or marking
Design Tips for Copper CNC Milling
When designing parts for copper CNC milling, remember:
- Keep walls thick enough – At least 0.02″ (0.5mm) thick
- Round inside corners – Use at least 0.005″ (0.13mm) radius
- Avoid very deep pockets – Keep depth less than 4x width when possible
- Consider thermal expansion – Copper expands more than many metals when hot
- Plan for machining marks – Some surfaces may need post-processing
