C36400 Brass (also called Low-Lead Brass, Plumbing Brass, Eco-Friendly Brass, and High-Strength Lead-Reduced Brass) is a premium copper-zinc alloy designed for potable water systems, hot forging, and precision machined components requiring low lead content and enhanced mechanical strength.
With excellent dezincification resistance (DZR), superior hot workability, and strong pressure performance, C36400 is widely used for valve bodies, plumbing fittings, sanitary parts, connectors, and forged components.
Available as C36400 Brass Rod, Bar, Tube, Forging Stock, and OEM Machined Parts, fully compliant with ASTM, UNS, RoHS, NSF, and EU drinking-water regulations.

FAQ
Q1: What differentiates C36400 from C36300 or C36500?
C36400 offers:
Higher strength
Improved pressure resistance
Balanced low-lead content
Superior hot forging performance
It is commonly chosen for heavy-duty plumbing and valve components.
Q2: Is C36400 suitable for drinking water systems?
Yes. It meets global low-lead and DZR requirements, making it ideal for potable water fittings and valves.
Q3: How is machinability compared to C36000?
Lower than C36000 due to reduced lead content, but still excellent with proper:
