Gr2 Titanium Round Tube
GR2 titanium alloy is a common titanium alloy material for industrial use with good mechanical and physical properties.
Description
Gr2 titanium round tube is a pure titanium alloy, the most common of all pure titanium. Gr2 Titanium Straight Tube contains about 99.5% pure titanium, as well as small amounts of iron and oxides. Due to its good mechanical properties, bendability and toughness, Gr2 titanium alloy is widely used in aerospace, medical, chemical and petroleum extraction.

Titanium tubing (TA2/GR2) applications is a very reactive metal with a low equilibrium potential and a high tendency to thermodynamic corrosion in media. However, titanium is actually stable in many media, e.g. titanium is corrosion resistant in oxidizing, neutral and weakly reducing media. This is because titanium and oxygen have a great affinity, in the air or oxygen-containing media, titanium surface to generate a layer of dense, strong adhesion, inert oxidized film, protecting the titanium substrate from corrosion.
