Brass hexagonal hole perforated sheet is stocked to DIN 24041 (Hv). The alloy provides good atmospheric and fresh-water resistance; unsuitable for ammonia service and is non-magnetic; the practical service limit is approx. +200 °C. Property data, alloy comparison and the specification table follow.
Why Choose Brass for Hexagonal Hole Perforated Sheet
The decorative and spark-resistant screening alloy. For hexagonal hole perforated sheet, this matters when good atmospheric and fresh-water resistance; unsuitable for ammonia service is the controlling requirement.
Alloy Properties

| Service temperature | approx. +200 °C |
| Corrosion characteristic | Good atmospheric and fresh-water resistance; unsuitable for ammonia service |
Corrosion Behavior in Filtration Service
Copper and brass hexagonal hole perforated sheet resist atmospheric corrosion and fresh water well, tarnishing to a stable patina. Avoid ammonia and ammonium compounds (stress-corrosion cracking of brass) and strong oxidizing acids. In marine service, phosphor bronze outperforms plain brass.
Comparable Alloys
Within the copper family: brass for economy and appearance, phosphor bronze for fatigue strength and marine air, pure copper where conductivity (EMI shielding) is the point. For structural filtration duties, stainless 304/316 is the usual alternative.
