Günther + Schramm is starting 2021 with new materials: The system service provider for steel, stainless steel and aluminum will be offering new lead-free aluminum alloys in its product range in the future. The expansion of the product portfolio complies with the current RoHS directive and offers further advantages for various applications and machinability.
Günther + Schramm is expanding its range with two new aluminum alloys: EN AW-6026 LEAD FREE with a diameter of 20 to 250 mm and EN AW-2033 with 30-150mm. The alternative program is supplemented by the alloy EN AW-2017A rods with a diameter of 20 to 250 mm and EN AW-2017A sheets with a thickness of 10 to 150 mm, which are already in stock. These lead-free alloys are in no way inferior to those with lead; quite the opposite: in addition to the reduction of hazardous substances in all new materials, 6026 LF is characterized above all by an improvement in the machining of the aluminium and at the same time allows higher productivity. In addition, the lead-free alloy has good corrosion resistance and excellent surface quality after machining. This makes it ideal for decorative anodizing and hard anodizing, but also for hot forming. 6026 LF is also used in the automotive, electrical and electronics industries, in the manufacture of threaded parts and in hot forging.
EN AW-2033 is characterized by its high mechanical properties and excellent machinability thanks to very short chip formation. The excellent quality of the surface after machining as well as the better anodizing quality and weldability also make this lead-free product ideal for use in the automotive, electrical and electronics industries, for precision turned parts, in cold forging and bolts as well as for screws, nuts and threaded parts.
Thanks to their excellent machining properties and high (fatigue) strength, 2017A bars and plates are particularly suitable for applications in mechanical engineering, defense technology, turned parts and high-strength structural parts.
"We are constantly adding new product groups," reports Manuel Mittelstädt, Head of Product Area Aluminum. "With the lead-free aluminum alloys, our customers benefit from pollutant-free alloys."
The high-strength, lead-free aluminum alloys also comply with the RoHS Directive: This directive on the restriction of the use of certain hazardous substances in waste electrical and electronic equipment regulates six substances, including lead. In the long term, the aim is to achieve a lead content of 0.0%.
