We are setting a milestone in terms of sustainability with the introduction of "low-carbon zinc" in die casting, thereby significantly reducing the carbon footprint in the supply chain. Low-carbon zinc stands for zinc that improves the CO2 balance and therefore also the CO2 footprint of die-cast parts.

Our three zinc die casting sites – POWER-CAST Drumeta, POWER-CAST Ortmann and POWER-CAST Ortmann s.r.o. – are among the first companies worldwide to use so-called "low-carbon zinc". Low-carbon zinc is zinc that is only extracted and produced with green energy. This achieves a CO2 footprint of less than 1.4 kg of CO2 per kilogram of zinc. In comparison, conventionally produced Z410 alloys generate about 4.4 kg of CO2 per kilogram of zinc.*

"The use of low-carbon Norzak Z410 clearly improves our in-house CO2 balance. We are also creating the best conditions for our customers to relieve the burden on their supply chains with the lowest possible CO2 emissions", says Jochen Gerlach, managing director of the POWER-CAST Group. Christine Marin, company shareholder and vice-president of Wirtschaftsvereinigung Metalle (trade association representing economic issues in the non-ferrous metal industry) since the beginning of November 2021, adds: "This is particularly important in view of the due diligence act "lieferkettensorgfaltspflichtengesetz" that is coming into force next year in Germany and will be applicable throughout the EU. Companies that are prepared for this future regulation can therefore increasingly gain economic advantages as well."


Zinc die casting is an efficient production process for castings. It is properties such as high strength, shielding against electromagnetic radiation or very good thermal conductivity that enable the broad range of zinc die casting applications. Modern casting machines are used to produce delicate and extremely thin-walled parts with the highest dimensional accuracy and the best conditions for subsequent surface finishes. Zinc castings can be recycled completely and almost without any losses at the end of their life cycle.

In conjunction with the circular economy and sustainability as well as the efficiency of modern melting and casting plants, the use of zinc die casting in the POWER-CAST GROUP with low-carbon Norzak 410 achieves unrivalled environmental performance.
