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 are demanded.

ECO BRASS

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

ECO BRONZE

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

ECO LITE

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.

ECO FORGE

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 61 leachate test for all ECO BRASS® and ECO BRONZE® products:

F1807 Fittings tested for NSF 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.
