Inconel

BMI supplies a wide range of INCONEL® Nickel–Chromium Superalloys engineered for extreme temperature strength, oxidation resistance, and corrosion protection.

These alloys retain their mechanical integrity in high-temperature, high-pressure, and high-stress environments, making them essential in aerospace, gas turbines, chemical processing, and marine applications.

All materials are sourced from approved mills and conform to ASTM / ASME / AMS standards for critical industries.

SPECIFICATIONS FOR EVERY REQUIREMENT.
