bronze for valves

Since 1961 we have been manufacturing copper based alloy ingots, including bronze for valves.
The tables below show the most common alloys for this field of application.

Many years of knowledge in refining techniques have enabled us to mix end forge raw material to obtain alloys with specific mechanical and chemical features for each production.
Standardisation and constant control of the production processes allow us to obtain copper based ingots in compliance with the required specifications.

If you need further information on the production of bronze for valves or a quotation, please contact our sales department.
