Nickel Aluminide Powder Description
Nickel aluminides powder is a type of intermetallic compound powder composed mainly of nickel (Ni) and aluminum (Al), such as NiAl, Ni3Al, or NiAl3. It is created through alloying processes and combines the properties of metals and ceramics, offering exceptional mechanical performance and thermal stability.
