  • Automotive (engine blocks, brackets)

  • Electronics (laptop shells, phone enclosures)

  • Robotics and drones

Benefits:

  • Lightweight but strong

  • Easily anodized

  • Excellent thermal/electrical conductivity

  • Fast, cost-efficient machining

2. Stainless Steel

Why It’s Popular:
Stainless steel is corrosion-resistant, strong, and durable—ideal for parts that must withstand harsh conditions.

Common Grades: 303, 304, 316
Applications:

  • Medical tools and implants

  • Food-grade machinery

  • Marine hardware

  • Heat exchangers

Benefits:

  • High tensile strength

  • Excellent corrosion and heat resistance

  • Long lifecycle in tough environments

3. Brass

Why It’s Popular:
Brass is highly machinable and attractive, making it perfect for both decorative and functional components.

Common Grades: C360
Applications:

  • Plumbing fittings

  • Electrical contacts

  • Musical instruments

  • Decorative hardware

Benefits:

  • Polishes easily

  • Antimicrobial and non-sparking

  • Excellent dimensional accuracy

4. Titanium

Why It’s Popular:
Titanium is incredibly strong and corrosion-resistant while being lightweight. Though difficult to machine, it’s often used where performance matters most.

Common Grades: Grade 2, Grade 5 (Ti-6Al-4V)
Applications:

  • Aerospace turbines and fasteners

  • Medical implants

  • Racing parts

  • Marine equipment

Benefits:

  • High strength-to-weight ratio

  • Resistant to extreme environments

  • Biocompatible

5. Mild Steel

Why It’s Popular:
Mild steel is strong, easy to machine, and highly affordable. It lacks corrosion resistance but can be treated with coatings.

Common Grades: 1018, A36
Applications:

  • Machinery parts

  • Automotive structures

  • Fixtures and jigs

  • General engineering applications

Benefits:

  • High ductility

  • Excellent machinability

  • Ideal for welding and forming

🧠 Conclusion

Choosing the right metal for your CNC machining project impacts everything from product life cycle to final cost. Whether it’s aluminum for lightweight efficiency, stainless steel for durability, or titanium for high-stress applications, each metal has its place in modern manufacturing.
