Exceeding industry standards
Our ecoline lead-free brass alloy consists of alloys with proven industry performance that are highly machinable, dezincification and stress corrosion cracking resistance. In addition, ecoline alloys are a great choice for customers that demand sustainable solutions for their raw materials.
Economical
With our ecoline alloys, recyclability is not affected in any way. And when changing materials within the same alloy family, the machine does not need to be cleaned.
Efficient
When compared to lead-containing alloys, ecoline alloys have excellent machinability and hot formability at reduced temperatures, making them remarkably efficient.
Experience
When it comes to the transformation from lead-containing to lead-free alloys, Wieland customers can rely on the long-standing and comprehensive expertise of our ecoline experts. With extensive industry expertise as well as detailed process and product knowledge, we find solutions to our customers’ challenges.

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.
