Specialty Alloys

In addition to traditional 300 series stainless steel, we have the capability to produce knitted wire mesh products in specialty alloys such as Monel® 400. Known for its ability to withstand harsh environments and extreme working conditions, CWI Tech-Mesh™ is specifically engineered to endure all the challenges faced by oil and gas industries. Whether you are replacing an existing unit or specifying a custom solution, Central Wire offers only the highest quality finished products.

Need a different material for your oil mist eliminator? Inconel® alloys are always available upon request. Visit our stainless steel alloys page for additional information about our 304, 316, 321, and 347 stainless steel. As an added benefit, CWI Tech-Mesh™ uses only made in the USA materials provided by other Central Wire factories. Having a close-knit supply chain means you can get the exact product you need without sacrificing your quality standards.
