ot4-1 is a wrought titanium-aluminum-manganese alloy. The material designation ot4-1 means:

  • OT - experimental titanium;
  • 4-1 - experiment number.

The wrought alloy consists of approx. 93-98% titanium, approx. 1-2.5% aluminum and approx. 0.7-2% manganese. It can be easily processed by cold and hot forming. The material is also characterized by excellent weldability with all common welding processes and good corrosion resistance. However, ot4 has a rather low strength and tends to become hydrogen embrittled.

ot4-1 is offered at Evek GmbH at a good price. Our products are characterized by their high quality. You buy GOST steels safely and reliably.

In the annealed state, ot4 is mainly used in aircraft construction for the production of supporting structures. It is also used in the production of thin-walled, difficult-to-shape parts that are operated over a long period of time at temperatures of 300 ° С (max. 30000 operating hours) up to 350 ° С (max. 2000 operating hours).

ot4-1 has the following characteristics:

  • good cold and hot formability;
  • excellent weldability;
  • good corrosion resistance;
  • quite low strength;
  • tends to hydrogen embrittlement.
