Material & Process Capability

Ti-6Al-4V is an alpha-beta titanium alloy characterized by its strength-to-mass ratio and corrosion resistance. It is a lightweight yet strong alloy suitable for highly loaded structures, including aerospace jet engines, gas turbines, pressure vessels and biomechanical components.

The Velo3D intelligent additive printing solution uniquely enables companies to build the parts they need without compromising design or quality – resulting in complex, higher performance parts than traditional casting techniques or other additive methods.

General Process

Three common heat treatment processes for Ti-6AI-4V include mill annealing, duplex annealing, and solution treating and aging. Parts built using Ti-6Al-4V on a Velo3D Sapphire® System can be heat treated in a manner similar to other methods.

This data sheet specifies the expected mechanical properties and characteristics of this alloy when manufactured on a Velo3D Sapphire System. All data is based on parts built with Velo3D standard 50 μm layer thickness parameters, using standard 15-53 μm Ti-6Al-4V grade 5 powder.
