Introduction to Aluminum
Aluminum is a versatile material with properties that make it ideal for CNC machining. Aluminum has excellent machinability, welding and electroplating properties as well as good corrosion resistance. The metal is also characterized by a high strength-to-weight ratio and good temperature resistance. After machining, aluminum has a low risk of deformation or defects and is easy to polish and color.
Because of these properties, aluminum is a broadly used metal in many industries, including automotive, defense, aerospace, transportation, construction, packaging, electronics, consumer goods and more.
