Introducing next-generation lead-free free-cutting brass "GloBrass"

~ Offering excellent cost effectiveness and environmentally friendly material contributing to achieving SDGs ~

Luvata’s parent company Mitsubishi Materials Corporation ("MMC") is pleased to announce that its Advanced Products Company has developed the next-generation lead-free free-cutting brass "GloBrass"1, which delivers improved cost effectiveness, electrical conductivity and hot workability than its predecessor "ECO BRASS"2. GloBrass and ECO BRASS are compliant with RoHS directive3 and other regulations concerning lead. 

GloBrass is a lead-free brass, which reduces metal costs by revising the mixture ratio of copper and zinc while having excellent machinability and strength. GloBrass has improved electrical conductivity to 16%, almost double that of ECO BRASS, and enhanced hot workability4 attracting a wider range of markets and applications including electrical and electronic components that require good electrical conductivity. 

GloBrass is a lead-free brass, which will contribute to a broader range of customers and industries in the global market. Additionally, GloBrass is available to customers looking for a more environmentally friendly brass or developing new products that will benefit from its excellent cost effectiveness, electrical conductivity or hot workability. In addition, comprehensive product support in terms of specifications, proper cutting conditions or cutting tools is available in coordination with our Metalworking Solutions Company. 

Lead is hazardous to human beings and the environment. The environmental regulations concerning lead have been expanded and strengthened globally with Europe's RoHS directive, ELV directive5 and other rules. Furthermore, the United Nations Sustainable Development Summit formulated new Sustainable Development Goals (SDGs)6 for 2030, thereby raising corporate social responsibility as well. 

To help solve such issues, MMC put ECO BRASS lead-free free-cutting brass on the market in 2002, followed in 2015 with C87870 (SnECO), which excels in corrosion resistance. This time MMC now unveils GloBrass the next generation lead-free free-cutting brass, which contributes to Goal 6 (Water and Sanitation), Goal 9 (Industry, Innovation and Infrastructure) and Goal 12 (Sustainable Consumption and Production) of SDGs 2030. 

Mitsubishi Materials Group, under the corporate philosophy "For People, Society and the Earth," pursues the vision that "We will become the leading business group committed to creating a sustainable world through materials innovation, with use of our unique and distinctive technologies, for People, Society and the Earth." Going forward, we will continue to build a richer society by making unique materials that meet customers' needs and providing processing solutions best suited to each customer.

2ECO BRASS is the world's No.1 lead-free free-cutting brass in terms of sales and is registered by JIS, ASTM and EN. ECO BRASS world cumulative sales volume reached 300,000 tons in FY2019 (including sales by companies other than MMC), a material that is recognized globally as Europe and the US account for roughly 70% of the cumulative sales volume.

3RoHS (Restriction of Hazardous Substances) directive is a directive that restricts use of certain substances that are contained in electrical and electronic equipment.

4The ease of hot processing that heats metals beyond recrystallizing temperatures to transform them to sheets, pipes and other shapes.

5ELVs (End of Life Vehicles) directive is a directive enacted by the EU with the aim of mitigating environmental burden caused by hazardous substances contained in dismantled vehicles.

6SDGs (Sustainable Development Goals) are new "Sustainable Development Goals" due by 2030, which were unanimously adopted in United Nations Sustainable Development Summit held in September 2015. 17 goals and 169 targets are stipulated.
