Why TC4 Titanium Alloy Powder is the Ideal Material for 3D Printing

TC4 titanium alloy powder is a high-performance metal material primarily composed of titanium (Ti) as the base element, containing about 6% of the stabilizing α-phase element aluminum (Al) and about 4% of the stabilizing β-phase element vanadium (V). Additionally, it contains small amounts of iron (Fe≤0.25%), carbon (C≤0.08%), oxygen (O≤0.16%), nitrogen (N≤0.01%), and hydrogen (H≤0.01%). This alloy composition gives TC4 titanium alloy powder excellent comprehensive properties.
