High-precision CNC precision machining parts can be made from a variety of materials. We have prepared a list of the eight most common materials used by precision machining service providers for your choose.

1. Aluminum:

The aluminum is considered to be exotic in manufacturing. Aluminum is probably the most widely used CNC milling material. It could be machined faster than other materials which makes aluminum a more useful material for CNC machining. Thanks to its light weight, non-magnetic, corrosion-resistant and inexpensive features, aluminum is widely used in the production of aircraft components, automotive parts, bicycle frames and food containers.

2. Stainless Steel:

Stainless steel alloy is not affected by most stains and rust. The material is favored for its strength and corrosion resistance and can be used for anything from surgical equipment to electronic hardware. The stainless steel is a very versatile material that is relatively lightweight and durable, expanding its application in a variety of industries.

3. Carbon Steel:

Carbon steel is also one of the common materials for CNC machining. It is available in a variety of formulations, from which you can choose according to your application requirements. Thanks to its durability, safety, long shelf life, affordability and environmentally friendly nature, this material is mainly used for CNC machining.

4. Brass:

The brass is widely considered one of the simplest and most cost-effective materials for precision machining services, and is used for the manufacture of complex parts that require sophisticated functionality. The brass is easy to machine, smooth and clean surface, and can be used to the manufacture of medical devices, consumer products, electronic hardware and contacts, accessories, commercial products, etc.

5. Titanium:

Titanium is heat and corrosion resistant, so that it could be used for lots of industrial applications. Titanium is not affected by salt and water, widely used in the manufacture of medical implants, aircraft components and jewelry, etc.

6. Magnesium:

Magnesium is the lightest structural metal widely used by precision machining service providers. Magnesium has excellent machinability, strength and sturdiness make it very suitable for multiple industrial applications.

7. Monel:

The demand for the Monel alloy parts upon CNC machining is at an all-time high. It is primarily used for applications that are exposed to corrosive environments and require greater strength. CNC machining shops specializing in monel machining are rare because its machining is difficult and requires the high level of experience .

8. Inconel Alloy:

It is a nickel-based high-temperature alloy. It has gained popularity in recent years due to its various beneficial properties. Inconel alloy parts are suitable for environments that may suffer from water corrosion or oxidation. It is also suitable for applications where parts may be subjected to extreme pressure and heat.

In addition to the materials mentioned above, there are several other materials that are compatible with CNC precision machining processes. These include cemented carbide, tungsten, palladium, invar alloy, nickel, niobium, alloy steel, beryllium, cobalt, iridium and molybdenum. It is important to select the proper material after considering the application areas it will be used in, other machining activities, etc. Choosing the right material from multiple options is critical, as the material determines the success of the application.
