Information

Molybdenum Rhenium wire manufacturers tell you that molybdenum wire is made of molybdenum rods of various specifications through a series of hot rolling, rolling and drawing. Molybdenum wire often breaks during the production process of drawing, resulting in a decrease in the yield of molybdenum wire. Therefore, in order to truly improve the comprehensive yield of molybdenum wire, it is particularly important to understand the reasons for the breakage of molybdenum wire in the production process.

According to research, the reasons for molybdenum wire breakage are as follows:
1. Brittle fracture caused by central hole of molybdenum rod
The raw material of molybdenum wire is molybdenum rod, which is produced by powder metallurgy from molybdenum, and the finished product is porous. Molybdenum Rhenium wire manufacturers tell you that if the pressing is not uniform after hot rolling and rolling, the force cross-sectional area will change during subsequent drawing, resulting in large stress fluctuations in the deformation direction, resulting in the breakage of the molybdenum wire.
2. Brittle fracture caused by enrichment of impurity elements
Molybdenum Rhenium wire manufacturers tell you that there are two kinds of enrichment of impurity elements in metal molybdenum, one is enriched on the wall of the hole, and the other is embedded in the metal molybdenum. The high temperature strength and tensile strength of impurity elements are not as high as those of metal molybdenum, and they are easy to break at high temperatures.
3. Brittle fracture caused by internal cracks
Molybdenum Rhenium wire manufacturers tell you that when the molybdenum rod is hot rolled and opened, the deformation of the molybdenum material is not synchronized, which will cause molybdenum wire cracks. The crack further expands, and once the crack expands too much, the molybdenum wire will eventually break.
