Materials We Work With

At Istar Machining, we can cut, shape, and finish many different materials:

Material Type	Examples	Good For
Metals	Aluminum 6061-T6, Stainless Steel 316, Titanium Grade 5…	Airplane parts, car engines, medical implants
Plastics	ABS, PEEK, Nylon…	Lightweight parts, clear components, flexible items
Composites	Carbon fiber, G10…	Super-strong but light parts for racing cars and planes

For special projects, our team at Istar Machining can help you pick the best material for your needs. Need something that won’t rust? Stainless steel CNC machining is perfect! Want something light but strong? Try our aluminum CNC machining!

Metal CNC Machining Materials

Aluminum

Aluminum is popular because it’s:

Light weight (1/3 the weight of steel)
Easy to machine into complex shapes
Naturally resists corrosion
Good electrical conductor

Perfect for: Aerospace parts, electronics housings, automotive components

Stainless Steel

Stainless steel offers:

Excellent strength
Outstanding corrosion resistance
Good performance in high temperatures
Professional appearance

Perfect for: Food processing equipment, medical devices, outdoor applications

Titanium

Titanium has many uses due to its properties:

Lightweight: Low density, about one-third of steel.
Good machinability: Most aluminum alloys are very easy to CNC machine, allowing high cutting speeds and good surface finish. At Istar Machining, 6061 is one of the most popular and easiest to machine.
Good corrosion resistance: A dense oxide film naturally forms on the surface to provide protection. The 5xxx and 6xxx series are particularly corrosion resistant.
Good thermal/electrical conductivity: Widely used in heat sinks and electronic components.
Relatively low cost: Compared to many other high-performance alloys.
Easy to anodize: Surface treatments can be performed to enhance corrosion resistance, wear resistance, and provide a variety of colors.

Copper

Copper is also often chosen by customers as a material:

Conductivity: Pure copper is one of the most conductive metals (second only to silver), so it is often used in electronic connectors and conductive parts.
Strong processability: Copper is easy to cut (especially brass C360), and the processing efficiency is high
Corrosion resistance: Copper has good resistance to water and salt spray (bronze performs better in marine environments).
Strong thermal conductivity: Copper is often used in radiators and heat exchangers due to its excellent thermal conductivity

Other Metal

At Istar Machining, many customers choose other metals for CNC machining due to their application:

Magnesium: light weight, with the highest practical strength-to-weight ratio.
Nickel: has extremely high temperature resistance and corrosion resistance.
Carbon Steel: low price, very easy to CNC machine.
Alloy Steel: higher strength, hardness and toughness than Carbon Steel, with excellent heat treatment response.
Tool Steel: has extremely high hardness, wear resistance and heat resistance, but is difficult to machine

Plastic CNC Machining Materials

PEEK

PTFE (also called Teflon) is super slippery. Nothing sticks to it!

Good for:

Seals that keep liquids from leaking
Parts for making computer chips
Things that touch strong chemicals

Why customers love it: “The PTFE parts from Istar Machining don’t react with any chemicals in our lab. They stay clean and last forever.”

Nylon 6/6

Nylon is tough and doesn’t wear out fast. It bends a little but is still strong.

Good for:

Bushings that reduce friction
Rollers that things slide on
Parts that need to be strong but not heavy

Why customers love it: “The nylon rollers from Istar Machining work better than metal ones in our textile machines. They’re quiet and don’t damage the fabric.”

ABS

ABS is easy to work with and costs less. It’s good for testing ideas.

Good for:

Test models before making final parts
Cases for electronics
Parts inside cars

Why customers love it: “Istar Machining helped us test our design in ABS first. It saved us money before we made the final product.”

Ultem (PEI)

Ultem won’t burn easily and can be cleaned with hot steam. It stays strong at high heat (340°F or 170°C).

Good for:

Parts inside airplanes
Medical trays that need to be super clean
Parts around electricity

Why customers love it: “The Ultem parts from Istar Machining passed all our fire safety tests for our aircraft interiors. They met all the rules we have to follow.”

HDPE

HDPE won’t soak up water and is safe for food. It’s easy to clean.

Good for:

Tanks for water or chemicals
Cutting boards
Boat parts that touch water

Why customers love it: “Istar Machining made HDPE parts for our food processing equipment that are easy to clean and don’t wear out.”

Acrylic (PMMA)

Acrylic is clear like glass but lighter. It stays clear in the sun.

Good for:

Store displays
Light covers
Models of buildings

Why customers love it: “The clear acrylic displays Istar Machining made for our products look so good in our store. Customers can see our products from all sides.”

PETG

PETG can be recycled and stands up to many chemicals. It’s good for the earth.

Good for:

Medical device cases
Food boxes
Chemical storage

Why customers love it: “We like that Istar Machining can make our parts in PETG. It’s strong enough for our medical devices but better for the planet.”

CNC Products Produced by Istar Machining

Prototyping & Small Batches

Need a test part fast? We can make your first prototype in just 3-5 days! This helps you:

Test your design before making lots of parts
Show investors or customers a real sample
Find and fix problems early

Our CNC prototype machining service is perfect when you need just a few parts to try out your idea.

Production Runs

Once your design is perfect, we can make hundreds or thousands of parts with the same high quality. Our machines run day and night to deliver your order on time, every time.

Complex Shape Making

Some parts have tricky shapes with curves and angles that are hard to make. Our 5-axis machining can reach all sides of your part to create these complex shapes in one setup!

What is CNC Machining?

CNC machining is a way to make parts using computers to control cutting tools. The letters “CNC” stand for “Computer Numerical Control.” This means a computer guides the tools that cut away material to create your part. It’s like carving a statue, but with super-precise machines instead of hands!

Think of it as a smart robot that follows a map (your design) to cut metal, plastic, or other materials into exactly the shape you need.
