Nb521

Nb521 alloy introduction

Nb521 niobium alloy is a medium strength plastic niobium alloy by adding W, Mo, Zr alloying elements and a small amount of C elements to the niobium matrix, which further improves the mechanical properties of niobium alloy at room temperature and high temperature by means of solid solution strengthening and precipitation strengthening.

The alloy can be prepared by vacuum electron beam melting or vacuum electron beam + vacuum consumable melting to produce ingots, hot extrusion, forging, cold rotary forging, stretching and rolling to produce a variety of specifications of bars, forgings and plates.
The addition of W and Mo elements in the alloy is mainly due to its high melting point and similar atomic radius, which can form a replacement solid solution and achieve the purpose of improving the creep resistance and high temperature strength of the alloy matrix.
