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.

Bronze alloyUnit Tensile strength R Kg./mm²Unit Yield strenght* RS Kg./mm²Elongation A1 %Hardness test Brinnell** H d10/500/30Examples of application
G-Cu Al10 Fe5 Ni5  CC333G 65÷75 30÷40 4÷10 170÷220 This alloy is suitable for pieces that are strongly cold/heat stressed and has an excellent corrosion strength, even for marine corrosion. It has high attrition and cavitation strength. Examples of application: turbine joints, nozzles and plugs for Pelton gears, strongly stressed bearings, components for engine valves.
