|
Brass
is an alloy mainly composed of copper (Cu) and zinc (Zn).
Other components of this alloy are lead (Pb) and arsenic
(As).Stamping brasses can be divided into standard brasses
and dezincification-proof brasses (DZR/ADZ).Stamping alloys
comply to specific European regulations. Here following,
in the table, you can find an example of the main features
of their chemical compositions.
