5 Fabrication Materials That Can Be Used in CNC Machining

CNC (computer numerical control) machining has revolutionized manufacturing by enabling precise, automated production processes. One of the key factors that makes CNC machining so versatile is its ability to work with a wide range of raw materials.

This article will explore 5 common fabrication materials that can be used in CNC machining, highlighting their properties and their typical applications. By the end, you’ll have a better idea of which material might work for your specific project needs.

1. Aluminum

Aluminum is one of the most commonly used materials in CNC machining, and for good reason. It offers a perfect balance of lightweight properties, easy machinability, and strength. Its high corrosion resistance makes it suitable for both industrial and consumer applications.

CNC-machined aluminum parts are used in industries such as aerospace, automotive, and electronics. Examples include engine components, heat sinks, and custom enclosures.

2. Plastic

When you need lightweight, chemical-resistant, cost-effective materials, plastics are often the best option. CNC machining plastics can produce highly precise parts while keeping production costs manageable.

Plastics like ABS, nylon, and PEEK are used in industries such as automotive, medical, and consumer electronics. It’s often the first choice when developing prototypes, creating housings, and manufacturing gears that require flexibility and resistance to wear.

3. Brass

Brass is highly prized for its aesthetic appeal, excellent machinability, and superior thermal and electrical conductivity. Its smooth finish and golden sheen make it particularly favored for parts that require both form and function.

Brass is commonly used to produce fittings, valves, gears, and electrical connectors in industries such as plumbing, electronics, and precision engineering. Its easy machinability makes it the perfect choice for businesses that want to reduce lead times for metal fabrication.

4. Glass

Glass is a versatile and durable material widely used across multiple industries due to its unique properties. It’s highly resistant to chemical corrosion, offers excellent optical clarity, and can withstand high temperatures.

Glass can be tailored to specific needs through processes such as tempering, laminating, and coating, which enhance its strength and functionality. It’s commonly used in fields such as construction, electronics, and automotive. Applications include windows, display screens, optical lenses, and insulation materials.

5. Carbon Fiber

Carbon fiber is a high-performance material known for its exceptional strength-to-weight ratio and versatility. Composed of thin, strong crystalline filaments of carbon, it is lightweight yet remarkably durable. This makes it ideal for applications where weight savings are critical without compromising strength or structural integrity.

Carbon fiber parts and components can be found throughout the manufacturing sector, including the most critical equipment for industrial operations. Used in industries such as aerospace, automotive, and sports equipment, applications range from aircraft components and high-performance car body panels to bicycles, tennis rackets, and prosthetic limbs.
