Aluminum: An Introduction
CNC machining is ideal for aluminum because it has excellent machinability, welding, electroplating, and corrosion resistance properties. Aluminum is also easy to polish and color after machining and has a high strength-to-weight ratio, along with good temperature resistance. Aluminum is also easy to polish and color after machining.
Aluminum is widely used in a variety of industries, such as automotive, defense, aerospace, transportation, construction, packaging, electronics, consumer goods, etc.
