Lead-free copper alloy "Eco Brass" - Responding to environmental regulations!
Lead-free and cadmium-free copper alloys that comply with regulations on the content of substances such as lead and cadmium! They can also be used as an alternative to stainless steel, leveraging their second characteristic of strength.
"Ecobras" is a lead-free copper alloy that does not use lead. It is a groundbreaking high-performance material that serves as an alternative to conventional lead-containing free-cutting brass, while simultaneously solving issues related to stress corrosion cracking and dezincification. ● Excellent machinability In conventional free-cutting brass (C3604), lead within the metal structure improves machinability. In Ecobras, the addition of silicon forms κ and γ layers, which helps to fragment chips and enhance machinability. ● High strength comparable to stainless steel The tensile strength of Ecobras is 600 N/mm². It is a high-strength material comparable to stainless steel SUS304, with 1.4 times the strength of conventional brass materials. This allows for cost reduction through thinner and more compact products. ● Solves dezincification corrosion issues Ecobras has a low zinc content in the alloy, and the absence of electrochemically noble β phase in the matrix prevents dezincification corrosion. ● Solves stress corrosion cracking issues The reduction of zinc content, along with the addition of silicon, effectively addresses the problem of stress corrosion cracking. ● Excellent hot forgeability (equivalent to forging brass C3771) ● Superior solder wetting, brazing, and plating properties.
