Copper alloys

Basic product information


A broad variety of copper-based alloys: tin bronze, RG bronze, tin bronzes with high lead content (e.g. CuZn7PB15), aluminium bronze and brass alloys.


Alloys are supplied by default in 90 x 60 x 250 mm blocks with a weight of 9 - 10 kg.


As a standard, our alloys comply with international, Czech and Slovak standards EN, DIN, STN a ČSN.

We can manufacture alloys according to customer specifications on demand.


Every shipment is accompanied by a chemical composition certificate.

Before casting an alloy into blocks, we first check the chemical composition of the melted material using a spark spectrometer. Depending on the chemical analysis results, we fine-tune the composition to fully conform to the applicable standard or customer specification.

Our quality management relies on an integrated quality management system conforming to ISO 9001:2015. We are also holders of certificates ISO 14001:2015, ISO 45001:2018, and P.E.D..

Scrap metal purchasing

Since our copper alloy production involves the use of metal wastes, we can purchase from our customers non-ferrous metal waste on favourable terms. We at our foundry make efforts to exploit and recycle all types of non-ferrous metal waste and thus contribute to the environmental protection. As an end waste processing entity we are able to offer advantageous pricing and debt setoff.
