What Are The Properties Of Ti-6Al--4V Titanium Alloy?

Ti-6Al--4V titanium alloy has the advantages of low density, high specific strength, excellent toughness, good corrosion resistance, good processing performance, etc., it is a more ideal aerospace engineering structure materials.
Titanium alloy is a new type of structural material, it has excellent comprehensive performance, such as low density (~4.5g cm-3), high specific strength and specific fracture toughness, fatigue strength and crack expansion resistance, good low temperature toughness, excellent corrosion resistance, some titanium alloys, the highest working temperature of 550ºC, is expected to reach 700ºC. Therefore, it is in the aviation, chemical industry, medical care, shipbuilding and other industrial sectors to get Increasingly widely used in the aviation, chemical, medical, shipbuilding and other industrial sectors, the rapid development.

Titanium is another significant feature of corrosion resistance, which is titanium's affinity for oxygen is particularly large, can generate a dense layer of oxidized film on its surface, which can protect titanium from medium corrosion. Titanium metal in most aqueous solutions, can generate a passivated oxide film on the surface.

Therefore, titanium in acidic, alkaline, neutral saline solution and oxidizing medium has good stability, but in a certain medium, can continuously dissolve the oxide film on the surface of titanium, titanium in this medium will be subject to corrosion. For example, hydrofluoric acid, concentrated hot hydrochloric acid, flow acid and phosphoric acid, titanium is corroded because the solution dissolves the titanium surface oxide film. If the oxidizer or some metal ions are added to these solutions, the titanium surface oxide film will be protected.
