CNC Machining in Aluminum
Aluminum is an ideal material for many industries due to its excellent mechanical properties. Aluminum in CNC machining has many advantages including: lightweight, affordability, flexibility, durability, and corrosion resistance. Nowadays, precision machined aluminum parts are becoming more and more popular in aerospace, consumer electronics, automation equipment, military, automobiles, sports equipment, medical, etc.
- High machinability and ductility
- Good strength-to-weight ratio
- High thermal and electrical conductivity
Advantages of Aluminum
Lightweight
Aluminum is about a third of the weight of steel, which makes it easier and cheaper to transport than most other metals.
Strength
The strength of aluminium can be adapted using varying alloying elements to provide better benefits including higher strength or easier formability.
Corrosion Resistance
Aluminum is a corrosion-resistant metal that naturally generates a protective coating, this protective aluminum oxide layer helps protect the surface of the metal from corrosion.
Odorless, Non-Toxic
Aluminum is non-toxic and can be used in special sensitive fields, including food and medicine manufacturing machine parts, packaging parts, etc.
Thermal Conductivity
It is an excellent conductor of heat and is used as heatsinks in a variety of applications such as LED lights, electrical products, computer motherboards, etc.
Anodized
Anodizing can significantly improve the corrosion resistance of aluminum, increase the surface hardness and wear resistance, and have good decorative properties after the appropriate coloring treatment.
