Alloy CNC Machining

Q: Q: What's the smallest order you accept?

A : We can make as few as 1 part for prototypes, or thousands for big projects.

Q: Q: Can you help improve my design?

A : Yes! Our engineers will look at your design and suggest changes to make it work better and cost less.

Q: Q: How do you protect parts during shipping?

A : We use special anti-rust packaging and strong boxes to keep your parts safe.

Q: Q: What file types do you accept?

A : We can work with most 3D files like STEP, IGES, X_T, or drawings in PDF format.

Q: Q: How long will my parts take?

A : Most prototypes are ready in 3-5 days. Bigger orders usually take 10-14 days.

Alloy CNC machining is a modern way to make strong metal parts using computer-controlled machines. At Istar Machining, we cut and shape different metal alloys into exact shapes for many industries. Our machines follow computer designs to make parts that are super precise and perfect every time.

An alloy is a mix of metals that makes them stronger and better than just one metal alone. When we do CNC machining, we can work with many different alloys to match what you need your part to do.

Industries That Trust Our Alloy CNC Machining

Aerospace

Airplane parts must be perfect and light. Our aerospace CNC machining makes parts that meet strict airplane rules.

Medical

Medical tools and implants need to be safe and exact. Our precise machines make perfect parts for helping people stay healthy.

Automotive

Car parts need to be strong but light to save fuel. We make perfect parts for modern cars.

Energy

Parts for power plants must handle extreme heat and pressure. Our special alloy machining can make parts that last in these tough conditions.

Marine

Boats need parts that don't rust in salt water. We use special alloys that stand up to ocean conditions.

Materials We Use for Alloy CNC Machining

At Istar Machining, we work with many different alloys. Each one has special qualities for different jobs:

Aluminum Alloys

Aluminum is light but strong. It’s perfect when you need parts that don’t weigh much. We use different types:

6061/6063: Great for most jobs, with good strength and weight ratio. Perfect for cars and planes.
7075: Super strong aluminum for military and boats.
Mic-6: Special flat aluminum that stays flat when machined.

Our team at Istar Machining has deep experience with aluminum CNC machining for all kinds of projects.

Titanium Alloys

Titanium alloy is often used by our customers in the medical, aerospace, marine engineering, chemical equipment and other industries because it has some characteristics that other alloys do not have:

High strength-to-weight ratio: The strength is close to some steels, but the density is much lower.
Excellent corrosion resistance: It has strong resistance to seawater, chlorides and many chemicals.
Biocompatibility: It is non-toxic, does not react with human tissue, and is widely used in medical implants.
Good high temperature resistance: It can maintain strength at higher temperatures.

It has many varieties, among which Ti-6Al-4V (Grade 5) is the most commonly chosen by our customers.

Copper Alloys

Copper alloys are mainly divided into two types: Brass and Bronze

Brass – Copper-zinc alloy
It has good machinability (especially C360, which is regarded as the benchmark for machinability), good electrical/thermal conductivity, and good corrosion resistance. It has a golden appearance and is easy to electroplate, but its strength is lower than steel, so it is often used to process into: screws, nuts, valves, pipe fittings, musical instruments, decorative parts, electronic connectors, etc.
Bronze – Copper-tin alloy (may also contain aluminum, phosphorus, silicon, etc.)
Bronze is harder, more wear-resistant, and more corrosion-resistant than brass (especially seawater). It has good thermal/electrical conductivity. It has acceptable machinability, but not as good as C360 brass. Our customers often ask us to use it to customize: bearings, bushings, gears (worm gears), valve parts, ship propellers, sculptures, etc.

Special Alloys

For the most demanding jobs, we work with special metals:

Nickel Alloys: Extremely high temperature strength, creep resistance, oxidation resistance and corrosion resistance (especially acid and high temperature corrosion resistance). However, CNC machining is very difficult and requires extremely low cutting speeds.
Magnesium Alloys: The lightest structural metal with low cutting resistance and very high cutting speeds. However, the corrosion resistance is relatively poor, so we usually apply a coating to protect it.
