WHAT IS C45200 BRASS?
C45200 is a leaded yellow brass alloy belonging to the copper-zinc alloy family.
Typical composition:
Copper (Cu): 60–63%
Zinc (Zn): 34–37%
Lead (Pb): 1.5–3.0%
👉 Copper ensures corrosion resistance
👉 Zinc provides strength and hardness
👉 Lead improves machinability and chip breaking
