Tip welding

A large range of electrical contacts based on the alloys of silver for switchgear and controlgear used in the range 16amps - 100amps and where high bond quality is essential.
The diversity and flexibility of production methods used by Metalor Technologies is designed to meet most requirements in contact combinations and batch sizes from a few thousand to many millions of parts.

Example

Application

CIRCUIT BREAKERS: fixed and moving contacts are generally asymmetrical as regards the nature and composition of the contacts.

	Contact surface	Welding quality	Material
Fixed contact	9 to 50 mm²	> 80 %	AgC ET AgC ED AgC U AgZnO
Moving contact	9 to 50 mm²	> 80 %	AgNi E AgNi U AgW, AgWC AgSnO2

CONTACTORS: fixed and moving contacts are generally symmetrical as regards the nature and composition of the contacts

	Contact surface	Welding quality	Material
Fixed contact or Moving contact	12 to 50 mm² 12 to 50 mm²	> 80%	AgCdO AgSnO2 AgNi
