Brass y-strainer screens combines the construction of y-strainer screens (Y-strainer OEM replacement) with the properties of H65 / CuZn35: good atmospheric and fresh-water resistance; unsuitable for ammonia service, non-magnetic, service to approx. +200 °C. This page summarizes the grade data, its behavior in filtration service, comparable alloys, and the specifications supplied.
Why Choose Brass for Y-Strainer Screens
The decorative and spark-resistant screening alloy. For y-strainer screens, this matters when good atmospheric and fresh-water resistance; unsuitable for ammonia service is the controlling requirement.
Alloy Properties
| Grade designation | H65 / CuZn35 |
|---|---|
| Magnetic response | Non-magnetic |
| Service temperature | approx. +200 °C |
| Corrosion characteristic | Good atmospheric and fresh-water resistance; unsuitable for ammonia service |
Cleaning & Compatibility
Clean copper-alloy mesh with mild detergent or dilute citric acid; avoid ammonia-based cleaners entirely. In contact with more noble metals in wet service the copper alloy becomes the sacrificial partner — isolate or accept the loss rate.
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.
