How strong are titanium screws?
Our titanium screws are primarily made from Grade 2, Grade 5, and Grade 7 materials. All have been extensively tested and proven to maintain stable mechanical performance across a wide range of temperatures.
- For high strength with low weight, Grade 5 is the perfect choice.
- For corrosion resistance and non-magnetic performance, Grade 2 is ideal.
- For the harshest environments such as chlorine exposure or seawater, choose Grade 7.
All our titanium screws come with ASTM material certificates, ensuring transparent data and full batch traceability—so you can buy and use with confidence.

Titanium's resistance to chlorine corrosion
Titanium has exceptional resistance to chloride-induced corrosion. Even in environments containing sodium chloride (seawater), sodium hypochlorite (bleach), or chlorine gas, it can maintain a stable, rust-free surface over the long term.
This is because titanium naturally forms a dense, self-healing oxide film that protects against pitting and crevice corrosion caused by chloride ions.

Titanium screws FAQ
Is titanium good for screws?
Yes. Titanium is an excellent screw material, combining high strength, low weight, exceptional corrosion resistance, and non-magnetic properties.
What are the disadvantages of titanium screws?
Titanium screws are more expensive than steel and stainless steel, but they offer long-term value in terms of performance and lifespan.
Titanium is harder, has lower thermal conductivity, and is more difficult to machine, which increases production costs and slightly extends lead times.
Why are titanium screws so expensive?
Mainly because titanium is difficult to refine, challenging to machine (prone to cutting difficulties and high tool wear), and requires stricter quality control (such as vacuum cleaning, traceability, and precision control).
However, titanium screws can often be installed once and used for a lifetime, making them more cost-effective in the long run.
What is the lifespan of a titanium screw?
Under normal operating conditions, titanium screws can last over 10 years—and often much longer.
Are titanium screws safe for surgery?
Yes — titanium is biocompatible, non-magnetic, and widely used in bone and dental implants.
What’s the difference between titanium screws and stainless steel screws?
Titanium is lighter, more corrosion-resistant, and non-magnetic, while stainless steel is heavier and more cost-effective.
Can titanium screws be used for wood applications?
Yes — they resist rust, won’t crack wood, and are ideal for outdoor decks, docks, and boats.
