Introduction to Titanium CNC Machining
Titanium is a premium material chosen for the most demanding applications where exceptional strength-to-weight ratio, corrosion resistance, and biocompatibility are non-negotiable. While it presents unique machining challenges, its performance in extreme environments makes it indispensable for aerospace, medical, and high-performance industrial components. At Clarwe, we leverage our expertise and specialized processes to precision-machine Grade 1, Grade 2, and Grade 5 (Ti6Al4V) titanium, delivering parts that meet the highest standards of quality and reliability.
Key Advantages of Titanium:
Titanium vs. Other Materials
Titanium occupies a unique position in manufacturing, offering a combination of properties no other material can match. Compared to aluminum, it provides significantly higher strength and temperature resistance, making it essential for critical applications. While stainless steel offers similar strength, titanium is nearly 40% lighter and far more corrosion-resistant. Its main drawback, machinability, is expertly managed through Clarwe's vetted network and in-house quality control.
| Material | Strength | Weight | Machinability | Cost | Best For |
|---|---|---|---|---|---|
| Titanium | Very High | Medium | Difficult | $$$$ | Aerospace, medical implants, marine |
| Aluminum | High | Light | Excellent | $$ | Prototypes, automotive, consumer goods |
| Stainless Steel | Very High | Heavy | Good | $$$ | Medical tools, food processing, high-stress parts |
| Plastics | Medium | Light | Excellent | $ | Enclosures, wear-resistant parts, electrical insulation |
Titanium Alloys : Properties and Applications
At Clarwe, we recognize that selecting the correct titanium alloy is paramount for mission-critical components. That’s why we specialize in machining the most sought-after grades, each offering a unique balance of strength, weight, and corrosion resistance. From the commercial purity of Grade 2 to the high-strength properties of Grade 5, our material expertise ensures your precision parts perform reliably in the most demanding environments.
Common Titanium Alloys & Their Uses
