Nichrome Wire Mesh
Nichrome Wire Mesh for High-Temperature & Heating Applications | NiCr Alloy Screen
Nichrome Wire Mesh is a woven metal mesh made from nichrome alloy—an essential material composed primarily of nickel (Ni) and chromium (Cr). Known for its exceptional resistance to oxidation, high temperatures, and corrosion, Nichrome mesh is widely used in heating elements, thermal processing, filtration, and laboratory applications.
Nichrome woven wire mesh has a wide range of applications, including the aerospace, shipbuilding, military industry, chemical and other fields. It often used for hot gas filtration works, heating of tanks, electric furnaces, radiant heaters and so on.
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.
Plain Dutch Weave
Plain Dutch Weave introduces a variation by using wires of different diameters: thicker warp wires and thinner weft wires. The weft wires are woven in a plain weave pattern—over and under one warp wire—but the differing wire sizes produce slot-like, rather than square, openings. This structure excels at retaining very small particles while still allowing a relatively high flow rate, making it a popular choice for fine filtration needs. The thicker warp wires also contribute to good durability, enhancing its suitability for demanding applications.
Twill Dutch Weave
Twill Dutch Weave combines the Dutch weave concept with a twill pattern. Like Plain Dutch Weave, it uses thicker warp wires and thinner weft wires, but the weft wires pass over and under two warp wires with an offset, similar to Twill Weave. This results in an even tighter mesh than Plain Dutch Weave, enabling finer filtration capabilities. Additionally, Twill Dutch Weave can withstand higher pressures and maintain good flow rates, making it well-suited for applications requiring precise filtration under challenging conditions.
