Introduction
Common Metal Materials for CNC Machining
Based on our machining experience, the following are some common and high-performance metal materials:
Stainless Steel
Example Models: SUS304, SUS316
Features: Excellent corrosion resistance, high strength, and toughness. SUS316, due to the addition of molybdenum, is even more corrosion-resistant than SUS304, making it particularly suitable for use in marine or chemical environments.
Common Applications: Medical devices, food processing equipment, chemical equipment, and precision instrument parts.
Aluminum Alloy
Example Models: AL6061, AL6063
Features: Lightweight, high strength-to-weight ratio, excellent thermal and electrical conductivity, and easy processing. AL6061 is the most popular general-purpose aluminum alloy, offering a balance of strength and processability; AL6063 is known for its excellent surface finish and corrosion resistance.
Common Applications: 3C electronic product casings, bicycle frames, radiators, and architectural structural components.
Magnesium Alloy
Example Models: AZ91D, AZ31B
Features: Currently the lightest structural metal material, it offers an excellent strength-to-weight ratio and shock absorption properties, effectively reducing product weight.
Common Applications: Laptop casings, camera bodies, drone parts, automotive steering wheel frames, and other products requiring extremely high lightweighting requirements.
Conclusion
From durable stainless steel to lightweight aluminum and ultra-light magnesium, each metal offers unique advantages. Understanding the properties of these materials will help you more accurately implement your product designs.
