C69300 - Eco Brass

 is a high-performance lead-free brass alloy widely used as an environmentally friendly replacement for traditional leaded brass alloys like C36000. It is known for:

  • excellent machinability 
  • high corrosion resistance 
  • dezincification resistance 
  • strength comparable to some stainless steels 
  • potable water compliance 

It is commonly called:

  • ECO BRASS® 
  • UNS C69300 
  • CDA 693 
  • CuZn21Si3P 


Chemical Composition

Typical composition of C69300: 

ElementPercentageCopper (Cu)73–77%Silicon (Si)2.7–3.4%Zinc (Zn)BalancePhosphorus (P)0.04–0.15%Lead (Pb)Max 0.09%Tin (Sn)Max 0.20%Nickel (Ni)Max 0.10%Manganese (Mn)Max 0.10%  


Main Advantages

Lead-Free & Eco-Friendly

C69300 complies with many drinking water and environmental regulations because it contains extremely low lead content. 


Excellent Corrosion Resistance

Highly resistant to:

  • dezincification 
  • stress corrosion cracking 
  • potable water corrosion 
  • saltwater environments 


High Machinability

Machinability is around 80–85% of free-cutting brass, making it excellent for CNC machining and automatic screw machine parts. 


High Strength

Offers high tensile strength and durability suitable for industrial applications.
