Wrought copper-zinc alloys - Chemical composition
and forms of wrought products Part 2 : Leaded copper-zinc alloys
1 Scope and field of application
IS0 1640,
This part of IS0 426 specifies the chemical composition of
leaded copper-zinc alloys and lists the forms of wrought products in which they are currently available in commercial quantities,
For non-leaded and special copper-zinc alloys, see IS0 4261 1.

The chemical composition of the copper alloys is given in
table I. The composition limits do not preclude the possible
presence of other elements not specified. If the purchaser’s requirements necessitate limits for any other element not
specified, these shall be agreed upon between the supplier and
the purchaser. Percentage content of elements shown as “remainder” is usually calculated by difference from 100 %.
The designations used are in accordance with the principles laid
down in IS0 1190/l.
5 Forms of wrought products and mechanical
properties
The forms of wrought products in which these copper alloys
are available are given in table 2. The mechanical properties for
all forms of wrought products for which the symbol X is given,
are defined in the following International Standards :
IS0 16341 1, IS0 x34/2, IS0 1635, IS0 1637, IS0 1636,
IS0 1639, IS0 1640.
