High-Temperature Resistant Molybdenum Wire Mesh for Vacuum and Industrial Applications

Molybdenum wire mesh is a high-performance woven metal screen made from pure molybdenum wire (≥99.95% Mo). Known for its high melting point, excellent strength at elevated temperatures, and outstanding resistance to corrosion and chemical attack, molybdenum mesh is ideal for use in extreme industrial environments. It is widely utilized in vacuum furnaces, aerospace, nuclear power, and the electronics industry.

Molybdenum mesh is available in both plain weave and twill weave configurations, offering flexibility in filtration, shielding, and structural applications.

Weave Types Available

Plain Weave

Plain Weave is the simplest and most common weave pattern for woven wire mesh. In this design, each wire passes alternately over and under one wire in both the warp (longitudinal) and weft (transverse) directions, forming a criss-cross pattern with square openings. This straightforward structure provides a good balance between filtration and flow rate, making it suitable for applications where moderate particle retention and consistent flow are required. Its inherent strength and durability also make it a reliable choice for general-purpose filtration tasks.

Twill Weave

Twill Weave is a more intricate pattern where each wire passes over two wires and under two wires, with an offset in each row that creates a distinctive diagonal appearance. This design allows for a tighter mesh with smaller openings compared to Plain Weave, even when using wires of the same diameter. As a result, Twill Weave offers finer filtration while maintaining higher flow rates due to its increased open area. It is ideal for applications requiring enhanced particle retention without significantly compromising fluid throughput.
