Silver Graphite Brush Products
Material Relationship
The pure silver material provides high conductivity and low resistance while the graphite material provides self-lubricating properties. We are able to apply additives to the graphite material which improves the self-lubricating properties to better suit the dry atmospheres in high altitude applications. Our silver graphite brushes & contacts will not melt nor weld to connecting metal surfaces as the graphite material cannot be melted. Compatible with the following contact surfaces: brass, bronze & steel.
