BRONZE

BRONZE is an alloy of copper with the addition of other metals (tin, lead, zinc, aluminium and others).

It is available in round bars (Ø 13 – Ø 454), tubes (Ø 26/14 – Ø 504/426), square and flat bars in continuous casting (GC) .

Centrifuged (GZ) up to Ø 1500, raw and finished sizes in the following alloys.
