Aluminum for Custom Parts

Aluminum Material Overview

Aluminum alloys cover a wide band of properties, so the grade matters as much as the material name. The 6xxx series (6061, 6063, 6082) balances strength, machinability, and finish quality and covers most machined parts. The 2xxx and 7xxx series (2024, 7075) trade corrosion resistance and weldability for much higher strength. The 5xxx series (5052, 5083) is not heat treatable but resists corrosion best and forms cleanly in sheet work.

• 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: Aluminum is soft, scratches easily, and costs more than mild steel. Wrought strength also depends on temper, so specify the condition (for example 6061-T6) when the load path matters.
