Fabrication of Next-Generation Alloys Beyond Conventional Materials

High Entropy Alloys (HEAs) are next-generation alloys composed of multiple principal elements in near-equal proportions, offering excellent mechanical properties and high-temperature stability. InssTek’s DED technology precisely controls the composition of multiple elements, enabling the efficient fabrication of new HEA materials.

• Good Wear Resistance

Why High Entropy Alloys?

Conventional alloys are typically designed around a single principal element, which limits their ability to simultaneously enhance multiple properties such as strength, heat resistance, and corrosion resistance.
HEAs introduce a new alloy design concept that combines multiple principal elements in balanced proportions, simultaneously enhancing strength, wear resistance, corrosion resistance, and high-temperature performance to deliver excellent performance even in extreme environments.

Conventional Alloys

• Limited Strength
• Poor High-Temperature Stability
• Susceptible to Corrosion
• Low Toughness
• Poor Wear Resistance

HEAs

High Entropy Alloys
