Product Introduction

Wire cutting molybdenum wire is a kind of consumables made of precious metals such as molybdenum, which has high inter-layer peel strength. This kind of molybdenum wire plays an important role in the wire cutting process. It is used as the electrode wire to continuously move under the high voltage electric field to carry out pulse spark discharge erosion on the workpiece and cut metal forming.

Under the conditions of high temperature and heavy load, the coating has high interlayer peel strength, so it has excellent wear resistance. This characteristic makes molybdenum wire an indispensable material in metal thermal spraying technology, and is widely used in the surface thermal spraying of piston rings, synchronous rings, gearboxes and other auto parts. In addition, the sprayed molybdenum wire can also be used to repair worn mechanical parts, such as bearings, bushes, crankshafts, etc., and can be used as an intermediate transition coating.

In the wire cutting process, the electrical characteristics, mechanical characteristics and geometric characteristics of wire cutting molybdenum wire are very important. The electrode wire needs to be able to withstand large cutting currents, and the transmission of energy must be very effective to provide high frequency pulse current to achieve high surface finish. At the same time, the mechanical properties such as tensile strength, memory effect and elongation of the electrode wire also affect the processing effect. In terms of geometric characteristics, wire cutting molybdenum wires need to have geometric characteristics with minimal errors to ensure machining accuracy.

In addition, the use of wire cutting molybdenum wire in the secondary cutting process can significantly improve the dimensional accuracy and surface quality of the processed workpiece, reduce the surface roughness, and increase the hardening layer of the cutting surface, and improve the life of the mold.
