Physical Data: Carbon Brushes
for industrial and railway applications
Metal graphites are characterized by low electrical losses, enabling their use in battery-powered devices. In addition, this class of materials is predestined for use in high-current applications such as coating and electroplating. Our silver graphites go one step further. They have the lowest electrical losses, allow the highest current densities, high signal accuracy and ensure low electrical noise.
Due to their low swelling tendency, our metal graphites guarantee reliable operation even under the harshest environmental conditions. Their proven lower temperature rise compared with similar competitive materials means that you have less need to cool your machines. It also prevents the brushes from getting stuck in the brush holder. With our silvergraphites, you benefit from our cost saving two-component brushes as well as from the patented manufacturing process for the production of laser-welded contacts on springs.
Metal graphites are primarily used in battery-powered household appliances, low-voltage motors, high-current transmission, AC slip rings, and wind generators. Silver graphites are used for safe signal current transmission, voltage dissipation and shaft grounding.
