Special metal-graphite grade specifically designed for low absolute humidity conditions: low temperatures and/or low relative humidity. Suitable also for all other climate conditions. With reduced content of metal and special high conductivity graphite to achieve: very high electrical conductivity; no material expansion in all brush life; minimal wear even in the worst climate conditions; very quick patina formation in all operating conditions; all brushes are silver tamped; and this graphite for electrical applications is always manufactured in the same location under the same standards for 100% traceability.
