Types of Stamped Parts
Stamped parts are produced as single pieces, in pre-stamped strip and comb configurations. Depending on the requirements and application the contact and base material as well as the coating and attachment technology is carefully selected.
*'''Coated stamped parts'''
Stamped parts can be selectively or completely coated with precious metal, containing materials based on gold, palladium, and silver as well as
non-precious materials such as tin, nickel and copper.
*'''Brazed stamped parts'''
Brazed stamped contact assemblies are manufactured by two joining methods (see also chapter [[Attachment of Single Contact Parts#Brazing Processes| Brazing Processes]]). The contact material is either attached by resistance or induction brazing to base metal carriers as prefabricated contact tip or they are stamped from brazed semi-finished toplay strip. It is typical for brazed contact parts, that the contact material consists of silver based contact material and a good conducting copper base material with larger cross-sectional area for the usually higher current carrying capacity.
*'''Stamped contact parts with rivets'''
Modern stamping tools usually employ a modular design with integrated dimensional and functional controls (<xr id="fig:Progressive die for stamped contact parts"/><!--(Fig. 3.21)-->).

Depending on part and volume requirements, they are built with steel or carbide inserts that are also coated with a wear-resistant material such as TiN for longer life.
