Common Materials Used for CNC Machining Parts
CNC machining is a process that involves the use of computer-controlled machines to manufacture high-precision parts. The process involves the use of various materials that are suited to the needs of different industries. Some materials are better suited for machining than others. Here, we take a closer look at the most common materials used for CNC machining parts.
Aluminum is a popular material for CNC machining parts due to its versatility, excellent machinability, and cost-effectiveness. It is used in the manufacture of a wide range of parts, especially those that require high strength and low weight. The material is ideal for parts that are used in the automotive, aerospace, and medical industries, among others. Other advantages of aluminum include its resistance to corrosion, good thermal conductivity, and high strength-to-weight ratio.
Steel is another commonly used material for CNC machining parts. It is known for its excellent strength, durability, and resistance to wear and tear. Steel parts are essential in many parts of industries, such as automotive, aerospace, and marine, to mention a few. Steel offers a range of benefits, such as being resistant to corrosion, heat, and chemicals, making it ideal for use in harsh environments.
Titanium is a popular material for CNC machining parts in the aerospace, defense, and medical industries. The material's unique combination of high strength, low weight, and excellent corrosion resistance makes it ideal for use in critical applications. It is also biocompatible, making it suitable for use in medical implants.
Plastics are widely used in CNC machining, particularly in the automotive, medical, and consumer products industries. They are lightweight, inexpensive, and have excellent electrical and thermal properties, making them ideal for use in applications where weight reduction is essential. Some of the most common types of plastics used for CNC machining include acetal, polycarbonate, and nylon.
Copper is an excellent conductor of heat and electricity, making it ideal for use in electrical and electronic applications. It is also used in the manufacture of machinery parts that require high-precision machining. Copper is known for its high thermal and electrical conductivity, excellent workability, and resistance to corrosion.
While there are many materials used in CNC machining, the most common ones include aluminum, steel, titanium, plastics, and copper. Each material has its own unique properties, making it suited to different applications. For example, aluminum is ideal for parts that require strength and lightness, while steel is perfect for heavy-duty applications. Titanium is the material of choice for aerospace and defense applications, while plastics are ideal for low-weight applications. Finally, copper is best suited for electrical and electronic applications that require high conductivity..
