Lead-free, the deadline for RoHS exemptions is July 2021! We can provide materials that are lead-free and excel in machinability and corrosion resistance!
Si-BRASS silicon brass is a lead-free alloy with excellent machinability and corrosion resistance. Its superior forgeability and machinability result in good processability and high strength with excellent mechanical properties. This document includes research data on features and chemical composition, contributing to cost reduction challenges in material research and development. 【Have you addressed lead-free compliance?】 The deadline for lead-free and RoHS exemption items is July 2021. As for alloy components, lead content up to 0.35 wt% in steel, up to 0.4 wt% in aluminum, and up to 4 wt% in copper alloys is allowed. Future extensions are uncertain, and if not applicable, there may be regulations for lead content below 0.1%. 【Features】 ■ Complies with lead-free, RoHS directive, ELV directive, and Reach regulations, and is suitable for drinking water applications. ■ Usable with hot forging properties equivalent to C3771. ■ Copper products can achieve high strength comparable to SUS304, allowing for miniaturization and weight reduction of parts. ■ Capable of solving dezincification corrosion issues and stress corrosion cracking problems. ■ A globally registered material that meets world standards. ■ Thermal conductivity and electrical conductivity are one-third of those of brass and high-strength brass. *For more details, please contact us!
