Brass Wire Mesh – Plain, Twill and Dutch Weave for Filtration & Protection

Brass is a type of copper and zinc alloy materials, which contains 65% copper and 35% zinc. It has excellent non-magnetic performance and abrasion resistance performance.

Brass wire mesh is made of flat or round brass wires. The wires are plain weave, twill weave or dutch weave into wire mesh tapes, rolls and sheets. They can be used in different filtering, separating, protecting applications.
