Brass Wire Mesh in Brass (H65 / CuZn35) is used for screening, sieving and decorating with woven brass cloth that is spark-resistant, non-magnetic and keeps a warm gold color. The alloy gives good atmospheric and fresh-water resistance; unsuitable for ammonia service and is non-magnetic, with a practical service limit of approx. +200 °C.

Where Brass Brass Wire Mesh Is Used
- Fuel & gas handling: non-sparking strainer screens where steel mesh could cause sparks.
- Papermaking & pulp: traditional brass forming and backing wires.
- Architecture & lighting: decorative brass mesh panels, lamp shades and cabinet inserts.
- Laboratories: brass-frame test sieve cloth and sample screens.
Ordering Brass Wire Mesh in Brass
- Alloy: CuZn35 (H65) is standard; specify H62 for stiffer cloth or lead-free brass where water contact is regulated.
- Mesh: 8–20 mesh for decorative and strainer use; 40–100 mesh for sieving.
- Finish: Natural, lacquered to hold the gold tone, or antique-dark for interiors.
Mistakes to Avoid with Brass Wire Mesh
- Using brass in ammonia or seawater service, where it dezincifies and cracks.
- Expecting brass mesh to hold its color outdoors without lacquer.
