Product Introduction
Titanium Grade 5 square bar (Ti-6Al-4V) is the most widely used high-strength titanium alloy square bar profile in the metal industry. It is composed of titanium, aluminum and vanadium elements, featuring excellent comprehensive mechanical properties.
Titanium Grade 5 square bar boasts high tensile strength, low density, outstanding corrosion resistance, high temperature resistance and great fatigue resistance. It is lightweight yet durable, far superior to ordinary steel and stainless steel in anti-corrosion performance against seawater, acid and alkali environments.
With stable chemical properties and good machinability, weldability and formability, Ti 6Al 4V square titanium bar is easy to process into various parts and components. It is commonly applied in aerospace, aviation, marine engineering, medical equipment, chemical industry, petrochemical, sports equipment and high-precision mechanical manufacturing fields.
It is an ideal structural material for lightweight and anti-corrosion projects, perfectly balancing high strength, light weight and long service life.
