SAXONIA Technical Materials

SAXONIA Technical Materials GmbH, based in Hanau, Germany, is part of the internationally active SAXONIA Group, which has around 1,500 employees. With decades of experience in global markets and internationally recognized expertise, the company is one of the leading suppliers of high-quality contact materials, and silver-containing functional materials.

Contact materials made of silver and silver alloys are indispensable when it comes to electrical contacts in low voltage switching applications. Thanks to their outstanding material properties, they are the starting products for an extensive range of semi-finished contact materials for a wide range of applications.

Our range of silver-based contact materials includes fine silver and various silver alloys as well as silver-based composite materials such as silver-nickel (AgNi), silver-tin oxide (Ag/SnO2), silver-graphite (AgC), silver-tin oxide-indium oxide (Ag/SnO2/In2O3), silver-zinc oxide (Ag/ZnO), and silver-iron (AgFe).

Our silver-tungsten (carbide) materials (AgW, AgWC) and copper-tungsten (Cu/W) are manufactured using either the press-sinter infiltration (PSI) or press-sinter repress (PSR) process. The sintered contacts are ideal for all types of circuit breakers and protective switches.

With innovative solutions, technological expertise, and global experience, SAXONIA Technical Materials stands for technical materials in perfection.
