Material search
Material description
The material 3.7165 is the most widely used titanium alloy, whose main alloying elements are aluminium and vanadium. Thanks to its exceptional strength, toughness and resistance to corrosive media, the material is used in the aerospace industry, among others.
3.7165 also offers good hot formability and weldability. Compared to pure titanium, titanium grade 5 has the advantage that it can be hardened. It impresses with its low specific weight and a good ratio between mechanical load-bearing capacity and weight.
The grade 5 titanium material forms a very well adhering oxide layer, which provides very good corrosion properties.
AN OVERVIEW OF THE PROPERTIES OF 3.7165:
- Ti-Al6-4V is the most widely used titanium alloy
- Best ratio between weight and strength
- Good resistance to corrosive media such as salt water
Applications
- Aerospace
- Ultrasonic technology
- Motorsport
- Sports and leisure industry (e.g. boat accessories, bicycle construction, mountaineering equipment, etc.)
- Medical applications
