CuSn12Ni2-C (CC484K) chemical composition
High-tin cast bronze to EN 1982 with a deliberate nickel addition that refines the structure and raises hardness and toughness compared with CuSn12-C. Used for heavily loaded worm wheels and gear rims, spindle nuts moving under load, bushings and wear rings.

We cast CuSn12Ni2-C
Tin bronze castings by sand casting, and by centrifugal casting for bushings, wear rings and sleeves, machined in the group's own CNC machine shop, with the chemistry of every heat verified by optical emission spectrometer and EN 10204 3.1 certificates. Church bells are the craft the foundry started with.
- Sand casting at our foundry in Mandra, Attica; centrifugal casting for bushings, sleeves and liners
- Heat treatment at the foundry (water, oil or air quench); CNC machining in our machine shop in Perama
- Spectrometer analysis of every heat, mechanical testing and NDT
- EN 10204 3.1 inspection certificates; ISO 9001 (both plants) and ISO 14001 (foundry) certified
