26 SPECIAL EMO 2023 Promotional message Free-cuttimg, lead-free alloys by Eural. Ultimate yield strength comparison. Eural Gnutti, based in Rovato (Brescia province) and founded in 1968, is a world leader in the production of bars and profiles, made of high machinable aluminium alloys, for mechanical ma- chining processes. Its semi-finished extruded and drawn prod- ucts are used all over the world in the mechanical, automotive and aerospace sectors. Eural invests constantly in the research and development of the best materials to be used, in plant technologies and in the thermal and mechanical treatment of semi-finished products. Free-cutting lead free alloys The highly extensive production programme meets most of the market’s technical requirements. In addition to supplying traditional alloys in the 2000 (Al-Cu) family, namely 2011, 2017A, 2007 and 2024, and those in the EURAL GNUTTI SpA Via S. Andrea, 3 25038 - Rovato (BS) Tel. +39 030 7725011 eural@eural.com www.eural.com 6000 (Al-Si-Mg) series, such as 6082, 6061 and 6064A, and finally the 7000 (Al-Zn-Mg) series, including the 7075 (for which there is the highest demand), in the last 20 years Eural has es- tablished itself as an innovator and developer of new solutions for the industry, in compliance with norms that typically apply - or will apply - in the sector, thereby catering to the needs of clients around the world. More specifically, Eural has recently completed its range of free-cutting LEAD FREE aluminium alloys. European regulations that govern and restrict certain chemical elements in the field of mechanical engineering, such as lead, have recently become particularly stringent and increasingly geared towards a drastic reduction or elimination of its use. Lead has always been used to ensure the machinability of semi-finished metallurgical prod- ucts such as brass, steel and aluminium. In anticipation of the new, more restrictive EU regulations, Eural has for some time been working on its LEAD FREE project. Its latest product is the 2077 alloy, which joins the now very well-established 6026LF and 2033. All these alloys have been developed to guarantee exceptionally high machining performance features, thanks to a remarkably fine chip formation. The field of hard alloys, i.e. those with a high mechanical perfor- mance, was in fact lacking an alloy that did not penalise perfor- mance in terms of machinability. The 2077 alloy is an excellent solution that ensures extremely high productivity levels, while also conforming to the most stringent technical requirements, outperforming alloys such as the 2024 and the 2014, and in some cases even able to compete with the 7075. In addition, the recently created 2077 also displays a particularly high ultimate yield strength (Rp0,2), so it can be a valid alternative to other metals, including the most common types of stainless steel, cast iron and brass. The best option on the market Eural’s LEAD FREE alloys are currently the best option available on the market for highly machinable aluminium alloys. Registered under and governed by international directives, they comply with regulations that now apply or are soon to come into force, and guarantee an excellent level of performance, including excep- tionally fine chip formation and remarkable minimum mechanical characteristics, and offer a wide range of possible applications.
