Industrial Use
Titanium Grade 2 seamless square tube is available in both welded and seamless forms. It is widely used in automotive, marine, aerospace, medical, and oil & gas industries where strength, light weight, and corrosion resistance are
critical.
The alloy’s excellent corrosion resistance makes it suitable for harsh environments, including seawater and
chemical exposure.
Its high strength-to-weight ratio ensures superior performance in structural and pressure-bearing
applications.
Titanium’s non-magnetic and biocompatible nature makes it ideal for medical and electronic applications.
Titanium square tubes are also popular in decorative and architectural projects due to their clean metallic finish and aesthetic appeal.
