High-Purity Molybdenum Mesh for Industrial Use

Molybdenum mesh is a functional industrial material made by precision processing high-purity molybdenum into wires and then weaving them into mesh. It combines molybdenum's extreme environment resistance with the filtering, supporting, and conducting advantages of mesh structures. Its mesh size is precisely controllable, and in harsh working conditions such as high temperature above 1600℃, strong corrosion, and high vacuum, it can not only achieve efficient filtration and uniform flow distribution but also maintain structural stability without deformation. It can replace conventional materials such as stainless steel mesh and nickel mesh to solve pain points in high-end manufacturing such as "high-temperature failure" and "insufficient precision", making it a key supporting material in fields like aerospace, metallurgy and chemical industry, and electronics and power.
