Why Aluminum? An Overview of Its Advantages
Before exploring the technical details, it’s important to understand why aluminum is such a popular material in manufacturing:
– Lightweight
– High strength-to-weight ratio
– Corrosion resistance
– Thermal conductivity
– Recyclability
– Machinability
Types of Aluminum Used in CNC Machining
Different aluminum grades offer different benefits:
• 6061 Aluminum: general-purpose, good strength, weldability.
• 7075 Aluminum: aerospace-grade, high strength.
• 5052 Aluminum: excellent corrosion resistance.
• 2024 Aluminum: high fatigue resistance.
• 5083 Aluminum: marine-grade, high strength.
