Material
Copper is the best metal for conducting heat and electricity. We machine it into precise parts with CNC.
Overview
Copper is the best metal for conducting heat and electricity. We machine it into precise parts with CNC.
Copper is a soft, reddish metal. It is the top choice for electrical and thermal parts because it conducts so well.
Computer-controlled mills and lathes cut a solid block into a precise part.
Tight-tolerance parts for prototypes or production, finished to your drawing.

Why Copper
The best electrical and thermal conductor among common metals.
Resists many environments, including seawater.
Soft and ductile. Cuts quickly with sharp tools.
Forms and bends without breaking.
Material Options
We stock common grades. Tell us your need and we will pick the right one.
High conductivity. The standard electrical copper.
Ultra-pure for the highest conductivity.
Free-machining copper for fast turning.
How It Works
From your file to a finished part in five clear steps. Start with a free quote.
Upload your STEP or STL file and drawings. Get a clear, factory-direct quote with free DFM feedback, usually within 24 hours.
Our engineers check wall thickness, tolerances, and features. We suggest changes that save cost and improve quality.
We cut your part from a solid block with mills and lathes in our machine shop.
We remove burrs, then apply the finish you need, such as polishing or plating.
We measure and inspect each part, then pack and ship worldwide with full tracking.
Applications
Electrical distribution and conductive parts.
Plates and fins that move heat fast.
Radio-frequency and shielding components.
Plumbing and process hardware.
Design Tips
New to this process? These simple rules help your part turn out well and cost less.
Keep walls thick enough to stay rigid. Thin areas can vibrate and warp during cutting.
Tight tolerances cost more. Only specify them where the function needs them.
Small chamfers and radii help tools last longer and parts look cleaner.
Finishes
The natural milled surface. Good for most functional parts.
A smoother, brighter surface for looks or low friction.
Nickel, chrome, or other coatings for corrosion or wear protection.
A chemical treatment that boosts corrosion resistance on some metals.
Why YiguProto
