Titanium - Infogalactic: the planetary knowledge core

2019-1-1 · A metallic element, titanium is recognized for its high strength-to-weight ratio. It is a strong metal with low density that is quite ductile (especially in an oxygen-free environment), lustrous, and metallic-white in color. The relatively high melting point (more than 1,650 °C or 3,000 °F) makes it useful as a refractory metal.

Aluminum 3D Printing Material Information - Shapeways

The support is then removed and polished away from the part during post-processing. Selective laser melting is unique because the high power laser provides enough energy to heat the aluminum powder above the melting point. This process fully melts the powder rather than just sintering it, creating a solid, homogeneous aluminum alloy.
