Material
Terminals are produced by using many different metals and alloys. The selection of appropriate metals ans alloys depends on both the terminal design and its intented applications. the metal and alloys used determine the efficiency and proporties of the contacts. tensile strength, elektric conductivity, corrosion and thermal performance are major criteria when it cones to rating diffrent applications. Brass, phosphor bronze, steel, copper, aluminium, German silver are common metals and alloys used.
Plating
Plating to improve resistance to corrosion of the terminal is doneç the mechanicel and electricial inteprity of terminals which also extend their application range for specific requirements. Plating is done either by pre-plating or post plating by electroplating system. the best plating system is electroplating. Plating coatings can be made in different thicknesses and brightness according to customer deman. Plating is possible in copper, tin, nickel, silver as well precious metals.
Application Data
Material & Plating Type |
Max. Temp |
