2B titanium welding wire

Alloy 2B

Titanium alloys are paramagnetic, wear-resistant, durable, and have a number of qualities that play an important role in technical industries. The use of titanium alloys is very promising in mechanical engineering, where heat resistance, corrosion resistance combined with specific strength are important. It is also actual in aviation, shipbuilding, rocket and rail transport. Some specific structural properties of titanium are of great interest to the food and chemical industries.

Alloying

Titanium high-strength alloys are alloyed with vanadium and aluminum, while heat resistance is achieved with molybdenum and aluminum additives. Most titanium alloys used contain molybdenum, aluminum, and vanadium at the same time. Such alloys are distinguished by particularly high strength and corrosion resistance. Aluminum is the main alloying element, and is as important to titanium alloys as carbon is to iron. Molybdenum is considered the second most important component.
