ErNi4B is an intermetallic compound in the erbium-nickel-boron system, combining a rare-earth element with transition metals to create a hard, brittle phase material. This is a research-phase compound primarily of scientific and materials development interest rather than an established commercial alloy; the erbium-nickel family is investigated for potential applications requiring high hardness, thermal stability, or specialized electromagnetic properties, though practical engineering use remains limited compared to conventional superalloys or tool materials.
