Various initiatives in Switzerland and Europe are calling for harmful substances like lead to be phased out. Roth is supporting this shift towards more environmentally friendly and harmless materials. In addition to precision parts made from ECOBRASS, Roth now also offers components made from the lead-free brass eco SZ3.

On 21 July 2024, the last exemptions under the RoHS Directive, which restricts the use of certain critical substances in electrical and electronic equipment, will expire (the EU Commission is yet to decide on a further extension). This means that the maximum lead content for copper alloys is soon to be reduced to 0.1 percent. We have been keeping a close eye on these and other lead-related regulatory developments for some time now, in order to ensure full compliance with the stricter requirements. We are also noticing that more and more customers are choosing to use sustainable materials voluntarily. That is why we offer the lead-free brass alloy ECOBRASS and have recently introduced eco SZ3, an alloy from Wieland’s ecoline range.

Alternative to Ms58

ECOBRASS and eco SZ3 are excellent alternatives to the material Ms58. We can generally use these two lead-free brass options for all precision parts that are typically made with Ms58. These lead-free alloys are therefore suitable for a wide range of products in various industries, including electrical engineering, sensor technology and mechanical engineering.

High conductivity

As with ECOBRASS, the properties of eco SZ3 are very similar to those of conventional leaded alloys. While eco SZ3 stands out for its superior electrical and thermal conductivity compared to ECOBRASS, ECOBRASS has a higher resistance to stress corrosion cracking and is a dezincification-resistant material.

With eco SZ3, a lead-free brass alloy developed in Europe, we are pleased to be contributing to a lead-free future. If you would like to join us on this journey, we will be happy to discuss how you too can benefit from eco SZ3 and ECOBRASS.
