Nickel-Based Alloys

BMI supplies a premium portfolio of special-purpose Nickel-based alloys engineered for precision, strength, and advanced engineering applications.

These alloys are distinct from traditional Inconel and Incoloy families — offering unique combinations of elasticity, memory effect, magnetism control, and ultra-high temperature stability.

Applications include medical devices, jet propulsion systems, high-temperature turbines, cryogenics, and electronics.
