Bronze
The only group we produce ourselves. We cast solid and hollow bars from Ø20 to Ø500 mm in tin, aluminium and lead bronze.
J-01 Product group
The only group
we cast ourselves
Bronze is the only material in our range that we do not buy in but produce ourselves. We cast it centrifugally, in permanent moulds and in sand, from Ø20 to Ø500 mm, in our own plant in Novi Sad.
Standard sizes are kept in stock. Non-standard sizes we can cast even within the same day, and for a breakdown, an overhaul or a missing spare part the lead time is 24 hours.

Inspection and certification
We test and certify our alloys with an optical emission spectrometer. Each delivery comes with material quality documentation. Across more than 1,000 tonnes of bronze delivered, justified complaints amounted to 1.5%.

Size and alloy are enough. If you have no drawings, describe where the part goes — we will propose the alloy and the casting method.
