Cast parts from high-performance-aluminum and -bronze
Impossible? Not for us!
According to leading scientific foundry institutes, ductile special aluminum and bronze cannot be cast as pressure-tight parts, and they certainly can't be welded. But we do exactly this every day, producing in our sand-casting foundry safety components with high ductility or with high ductility and high strength from corrosion-resistant, food-safe high-performance alloys we have developed ourselves: a genuine alternative to steel or stainless steel.
Product properties to fit your needs
You're looking for aluminum castings with high ductility? We supply high-performance aluminum alloy with high or very high ductility, and also a heat-treated version with very high strength and high ductility – both at the test sample and at the casting.
- Fully machined
- Assembly of the castings with other components
- Authorisation or inspection / approval by national/international classification institutes
Silo vehicles – collars, lids, discharge funnels
For leading national and international vehicle manufacturers like Köhler and Feldbinder, we produce seawater-resistant, pressure-tight weldable cast parts with a tensile strength of A = 12 % according to the European Pressure Equipment Directive (PED / AD2000). Only the high-stretch ductile aluminum alloys developed by us enable the construction of mobile pressure vessels such as silo vehicles or silo rail wagons made from aluminum.
Linde – closing flaps for valves
For Linde's gas equipment we supply closing flaps for valves made from ductile, high-tensile aluminium alloys. These lighter flaps enable the flaps to be closed faster or using less force, which in turn reduces energy consumption, purchase costs and operating costs.
Feldbinder – fully processed and assembled cast parts
Whether they are thermally treated, machined or assembled, Fehrmann supplies safety components in accordance with the requirements of the customer's production flow. Fehrmann also cooperates with its customers to develop, construct and certify completely new cast parts as required. The sliding lid shown here is just one example.
