As environmental regulations become increasingly stringent worldwide, manufacturers are seeking lead-free material solutions that maintain performance, reliability, and productivity.
These highly recyclable, lead-free free-cutting brass materials comply with the RoHS Directive and have been developed as practical alternatives to conventional leaded brass.

ECO BRASS offers selectable performance for a wide range of applications and design requirements, while GloBrass is a versatile general-purpose grade designed for broader use.
By combining excellent machinability with high reliability, these materials help expand design freedom in applications where lead-free solutions are required. With cumulative global sales exceeding 400,000 tons, primarily in Europe and North America, ECO BRASS has established a proven track record in applications where performance and reliability are essential.
Mitsubishi Materials contributes to the wider adoption of lead-free brass and to sustainable manufacturing through the materials technology and intellectual property it has developed over many years.

Developed by Mitsubishi Materials in 1998, ECO BRASS is a pioneer in lead-free free-cutting brass, combining excellent machinability with the benefits of a lead-free material.
In addition to its machinability, it offers superior resistance to dezincification and stress corrosion cracking compared with conventional free-cutting brass.
With high strength and excellent wear resistance, ECO BRASS can be used as an alternative to conventional free-cutting brass such as C3604 in a wide range of applications, from plumbing components to various mechanical parts.

Developed in 2020, GloBrass is a lead-free brass based on the technology and expertise accumulated through ECO BRASS.
It offers excellent electrical conductivity and machinability, making it well suited for small precision components as well as electrical and electronic parts.
In addition, as a Cu-Zn-Si alloy system similar to ECO BRASS, GloBrass contributes to resource circulation through the collection and recycling of scrap.
