Molybdenum Tantalum Alloy

Material Introduction

The main component of molybdenum tantalum alloys is Mo-10Ta. Adding tantalum to pure molybdenum significantly improves the chemical corrosion resistance and high temperature resistance. These alloys are mainly used in sputtering targets for flat-panel displays.

Fabrication Process

By means of molybdenum alloy powder preparation, isostatic pressing, high-temperature sintering, and thermal deformation processing, molybdenum tantalum alloys have a density which is close to the theoretical density, thus ensuring optimal high-temperature performance.




Adding tantalum to the pure molybdenum structure improves the interatomic bonding force of the molybdenum alloy and forms a continuous solid solution. This improves the yield strength, plasticity, specific impedance and corrosion resistance of the molybdenum.
