About Franken Guss
Franken Guss GmbH & Co. KG is a foundry based in Kitzingen in Lower Franconia that produces customized cast parts made of iron and aluminium. The iron foundry processes 15 different iron grades using the sand casting process at a capacity of 80,000 tonnes per year, including grey cast iron with flake, spheroidal (nodular) and vermicular graphite including austempered (ADI) variants. The aluminium foundry achieves a capacity of 4,500 tonnes and works with the horizontal cold chamber die casting and laminar die casting processes. The company offers the entire value chain at one site: melting operation, in-house pattern shop, casting finishing, heat treatment, machining and assembly. As a development partner of its customers, Franken Guss implements design improvements up to weight savings. Buyers include the automotive industry for passenger cars and commercial vehicles, as well as the electromobility, wind energy, rail infrastructure and hydrogen production sectors. The company belongs to the JORA Group with the sister foundry Sachsen Guss in Chemnitz.

Materials and Processes
Grey cast iron with flake graphite (EN-GJL-200 to -350)
Four strength grades for versatile, economical cast parts with good thermal conductivity and noise damping.
Spheroidal graphite cast iron (EN-GJS-400-15 to 800-500-5, incl. ADI)
High-strength materials including austempered (ADI) variants for safety-critical and high-load automotive components.
Cast iron with vermicular graphite (EN-GJV-300)
Vermicular graphite cast iron with high thermal conductivity and strength for thermally stressed components.
Aluminium EN AC-AlSi9Cu3 (226)
Die casting alloy for bracket, impeller and connector bracket in the transmission sector.
Aluminium EN AC-AlSi12 (231)
Pure Si alloy for pressure-tight aluminium cast parts.
Aluminium EN AC-AlSi10Mg (239)
Heat-treatable alloy for high-strength chassis and body components.
