PD1707 Nickel Aluminide Powder (NiAl, Ni3Al or NiAl3)

Description

Nickel aluminides (Ni3Al) are intermetallic compounds that have long been considered potentially useful because, thanks to their ordered crystal structure, they are very strong and hard (lighter and five times stronger than stainless steel) and melt only at very high temperatures.

However, nickel aluminides have a serious weakness: they are very brittle, making it almost impossible to shape into reliable components. However lately several advances have been made in this area.

Nickel aluminide is an intermetallic material with properties similar to both a ceramic and a metal.
