We also have several materials used for CNC machining besides aluminum, steel, plastic, and urethane. Some examples include: Copper and brass: These materials are good conductors of electricity and are often used in electrical applications. Titanium: This metal is strong, corrosion-resistant, and biocompatible, making it ideal for aerospace, automotive, and medical applications. Magnesium: This material has a high strength-to-weight ratio and is commonly used in parts where strength is desired at the expense of weight. Wood: CNC machines can also be used to carve and shape wood, making it a popular material for artistic and decorative projects. Ceramics: These materials are often used in industrial applications due to their high-temperature resistance and durability. Composites: Materials such as carbon fiber composites are used for their strength and lightweight properties in applications ranging from sports equipment to aerospace.
