How to Extend the Service Life of Molybdenum Wires

Molybdenum wires are pressed and sintered from our high purity molybdenum powders to compact ingots by powder metallurgy and then drawing. As a leading molybdenum manufacturer, we are capable of providing wires with a range of diameter from 20 microns to 2mm. 

Many end-users would require a good quality of products. How to extend the service life of these wires? Here are some tips:

1.Installation 

Wires made of molybdenum are easily deformed and broken. Therefore, they can not be bended during installation. If bended, cut it off to avoid wire breakage during operation. The cutting fluid should also be replaced in time during use because it will turn black after a long time of use, which will directly affect the performance of products.

2.Operation 

When the wire is discharged during operation, it will also be damaged. However, due to the good mechanical properties of molybdenum, the damage is small. Therefore, it would be better to using low-energy processing parameters to reduce the damage. After running for a period of time when the color of wire becomes write, workpieces can be cut with normal high current. In addition, after replacing the wire, running new wire for 5-10 minutes before cutting the workpiece, so that the internal stress of the molybdenum wires can be released.

When the moly wire breaks during the operation of the cutting machine, most of the broken ends are within a dozen to dozens of turns after the reversing of the wire barrel. It can be seen that the metal wire at both ends of the head and tail is easier to be broken. Therefore, in the cutting process, the wire barrel is reversed to form a switch control block and move a little outward or inward at regular intervals.

3. Maintenance

Routine maintenance of molybdenum wire can also improve the service life, such as: daily storage, placement and time. It should be stored in a ventilated and cool place with low humidity, and the temperature is 20℃~25℃ to avoid oxidation. In addition, it should not be placed for more than 6 months. While using it, check whether the packaging is damaged or deformed.
