Aluminum in CNC Machining

In CNC machining, raw aluminum is gradually cut down to form the desired shape, a process controlled with precision by a CNC machine to produce almost any three-dimensional object. Aluminum alloys offer high machinability, ductility, and an excellent strength-to-weight ratio. They also possess high thermal and electrical conductivity, low density, and natural corrosion resistance, and they can be anodized for added protection. The strength-to-weight ratio of aluminum makes it perfect for applications requiring metallic strength without excessive mass. Custom aluminum machining is an excellent choice for precise and versatile machining needs.

• Lightweight: Aluminum is among the lightest metals, with just over 2.7 g/cm³ density. This makes it ideal for applications in transportation and other industries where weight is a vital factor.
• Corrosion Resistance: Aluminum naturally resists corrosion, which helps prevent oxidation. Combined with various coatings and finishes, this property ensures that aluminum CNC parts are durable and long-lasting.
• Conductivity: Aluminum is an excellent conductor of heat and electricity. This makes it ideal for many applications, similar to copper and other similar conductive materials.
• High Machinability: Aluminum is popular because it is easy to machine. It can be easily shaped, drilled, and folded, allowing for the creation of complex shapes.
• High-Temperature Resistance: Unlike some materials, aluminum maintains its properties at low temperatures, offering more flexibility in the machining process.

Selection note: Lower hardness can cause tool marks and chatter, the material scratches more easily than steel, and it costs more per kilogram than mild steel. Wrought alloys also lose strength at elevated temperature.
