2B titanium welding wire
2B Alloy
Titanium alloys are paramagnetic, wear-resistant, durable, have a number of qualities, which play an important role in the technical sector. The use of titanium alloys is very promising in the field of engineering, where important heat resistance, corrosion resistance, combined with a specific strength. This is also true in the aviation, shipbuilding, rocket, railway transport. Some specific structural properties of titanium are of great interest for the food and chemical industries.

alloying
High-strength titanium alloys are alloyed with aluminum and vanadium, and heat resistance is achieved doped molybdenum and aluminum. Most used titanium alloys containing both molybdenum, aluminum, vanadium. Such alloys have a particularly high strength and corrosion resistance. Aluminum is the principal alloying element, it is also important for the titanium alloys, both iron carbon. The second important component is considered molybdenum.
