Magnesium — CNC Machining Materials

Magnesium is the lightest structural metal. We machine it into precise, ultra-light parts with CNC.

Overview

What Is Magnesium CNC Machining?

Magnesium is the lightest structural metal. We machine it into precise, ultra-light parts with CNC.

Material: Magnesium

Magnesium is a light, silvery metal. It is the lightest structural metal and easy to machine.

Process: CNC Machining

Computer-controlled mills and lathes cut a solid block into a precise part.

Result: Precise Finished Parts

Tight-tolerance parts for prototypes or production, finished to your drawing.

Why Magnesium

Why Choose Magnesium for CNC Machining

Ultra-Light

About 35% lighter than aluminum. Best for weight-saving parts.

Easy to Machine

Cuts fast and extends tool life. Lower cost per part.

Good Stiffness

Strong for its weight. Good stiffness-to-weight ratio.

Dampens Vibration

Absorbs shock and noise better than aluminum.

Material Options

Magnesium Grades & Options

We stock common grades. Tell us your need and we will pick the right one.

AZ31B

The most common grade. Good strength and formability.

AZ91D

Higher strength for cast or machined parts.

WE43

Rare-earth grade for high temperature.

How It Works

How We Make Your Magnesium Part

From your file to a finished part in five clear steps. Start with a free quote.

Send Files & Get a Quote

Upload your STEP or STL file and drawings. Get a clear, factory-direct quote with free DFM feedback, usually within 24 hours.

Design Review (DFM)

Our engineers check wall thickness, tolerances, and features. We suggest changes that save cost and improve quality.

CNC Milling & Turning

We cut your part from a solid block with mills and lathes in our machine shop.

Deburr & Finish

We remove burrs, then apply the finish you need, such as polishing or plating.

Inspect & Ship

We measure and inspect each part, then pack and ship worldwide with full tracking.

Applications

Where Magnesium Is Used

Aerospace & Drones

Light frames and brackets that save weight.

Automotive Parts

Housings and brackets for fuel savings.

Electronics

Laptop and phone frames, heat spreaders.

Sports Equipment

Light handles and structures.

Design Tips

Easy Design Tips for Beginners

New to this process? These simple rules help your part turn out well and cost less.

Respect Minimum Wall

Keep walls thick enough to stay rigid. Thin areas can vibrate and warp during cutting.

Plan for Tolerances

Tight tolerances cost more. Only specify them where the function needs them.

Add Chamfers & Radii

Small chamfers and radii help tools last longer and parts look cleaner.

Finishes

Surface Finishes for Magnesium Parts

As Machined

The natural milled surface. Good for most functional parts.

Polishing

A smoother, brighter surface for looks or low friction.

Plating

Nickel, chrome, or other coatings for corrosion or wear protection.

Passivation

A chemical treatment that boosts corrosion resistance on some metals.

FAQ

Magnesium — Frequently Asked Questions

Magnesium is a light, silvery metal. It is the lightest structural metal and easy to machine.
CNC machining uses computer-controlled mills and lathes to cut a solid block into a precise part. It is fast, repeatable, and ideal for tight tolerances.
Magnesium is the lightest structural metal. It machines well, has good stiffness, and dampens vibration.
Magnesium (AZ31B–AZ91D) reaches about 200–280 MPa tensile strength. That is enough for light, working parts.
Send us your files. Most quotes return within a few hours on workdays. We never take more than 24 hours.
There is no strict minimum. We make a single prototype or a full production run.
Yes. We treat all files and ideas as confidential. We sign NDAs when you need them.
Yes. Our engineers review your design and suggest changes that cut cost, improve quality, or speed up delivery.
Anodizing, chromate conversion, painting, and powder coating.
Yes — we hold tolerances down to ±0.005 mm on CNC machining.
Yes. We can make samples for your approval. The sample cost is credited back on a production order.
