ECO Solutions

The E-Shield represents the ECO BRASS® and ECO BRONZE® lines of silicon-based copper alloys.

The E-Shield identity was developed to distinguish these lines and to represent strength, safety, environmentally sustainable and compliance where the highest purity products in the USA are demanded. We are proud to have an extensive supply of ECO solutions and can fulfill bulk orders for any of our ECO products. 


High performance Lead-Free* Silicon Brass Rod, Dezincification and stress corrosion cracking resistant.


Tough, Potable water castings, Dezincification resistant Wear-Resistant, Lead-Free* Bearing and Bushing Solution


Similar performance as Lead-Free* ECO BRASS, with less copper. Machinable and forgeable. Improved DZR and SCC resistance vs. C27450.

This is a developmental alloy. For sample request click here.


Highly forgeable Lead-Free* alloy that is dezincification and stress corrosion cracking resistant

* This product complies with 0.25% weighted average lead content on wetted surfaces in accordance with Safe Drinking Water Act (SDWA) / Federal Public Law No. 111-380.

Lead Leachate Performance

CDA sponsored project for independent laboratory measurement of lead leachate

NSF/ANSI/CAN 61 leachate test for all ECO BRASS® and ECO BRONZE®  products:

  • F1807 Fittings tested for NSF/ANSI/CAN 61 Compliance resulted in lead leachate below the detection limit of 0.5 ppb.
  • The ECO BRASS® and ECO BRONZE® family has a Day 3 Q value of 0.25 ppb.
