titanium 3d printed part

Titanium (Ti6Al4V) is a workhorse alloy. Versus Ti grade 23 annealed, the mechanical properties of Ti6Al4V are comparable to wrought titanium for tensile strength, elongation, and hardness. Final parts built in Ti6Al4V receive vacuum stress relief application.

Primary Benefits​

  • High stiffness and strength relative to weight
  • High temperature and corrosion resistance
