Copper Alloys

Need a different material for your bulk mesh or oil mist eliminator? Copper alloys are always available upon request. Copper alloys provide a number of benefits for your knitted wire mesh needs. Unlike other alloys, copper is both strong and pliable. A unique combination of high strength and high ductility makes copper ideal for mesh materials. Copper alloys have natural properties that can destroy a wide range of harmful microorganisms. Copper is resistant to corrosion and rust, which is key for all industries including refinery towers, food and beverage and filtration.

 

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. Download a copy of our alloys guide for convenient referencing, and do not hesitate to contact us with any additional questions.
