Overview
Brass flanges are widely used in plumbing, water supply, instrumentation, and decorative applications due to their excellent machinability, durability, and resistance to corrosion. They combine copper and zinc in varying proportions, resulting in superior strength while maintaining good ductility. Brass flanges are suitable for both industrial and commercial use.
