Aluminide Explained

An aluminide is a compound that has aluminium with other elements.^[1] Since aluminium is near the nonmetals on the periodic table, it can bond with metals differently than other metals. The properties of an aluminide are between those of a metal alloy and those of an ionic compound. Aluminides are used as bond coats in thermal barrier coating systems.^[2]

Examples

• Magnesium aluminide, MgAl
• Titanium aluminide, TiAl
• Iron aluminides, including Fe₃Al and FeAl
• Nickel aluminide, Ni₃Al

See category for a list.
