Abstract
Described is a method for forming a sieve material in which a sieve skeleton is thickened in an electrolysis bath with metal; in the bath as used at least one chemical compound is present having properties of both a first and second class brightener in such concentration and added with such a rate in view of the Ah (ampere hour) load that the internal stress in the finished sieve material is reduced in comparison to a sieve material produced in a bath comprising a conventional compound under conventional conditions. The invention also relates to a sieve material formed with the method described.
