Analysis and comparison of brush materials
1. Conventional brush materials for cylindrical motors:AgPd50/GMX215
High performance heat-resistant elastic material GMX215
NGK copper nickel tin GMX215 is a kind of age hardening copper alloy with nickel and tin added and metastable decomposition. It has high strength that can match with beryllium copper, and the highest level of corrosion resistance and heat resistance among existing copper alloys. It is suitable for high-performance elastic materials used in motor brushes, industrial machinery and other harsh environments.
2.Conventional brush materials for cylindrical motors:AgPd30/C7701
C7701
It has beautiful luster, deep drawing, excellent cold workability and ductility, corrosion resistance, strong fatigue resistance, good processing formability and weldability, good electrical performance, mechanical performance and radiation shielding performance. It has high mechanical properties, good casting properties and machinability, good corrosion resistance in air, fresh water and sea water, and stress corrosion cracking tendency. It is widely used in electromagnetic shielding, crystal oscillator shell, potentiometer blade, motor brush, etc.
3.Conventional brush materials for cylindrical motors:SP-1/GMX96
High performance conductive elastic material GMX96
NGK copper nickel tin GMX96 is a kind of age hardening copper alloy with nickel and tin added and metastable decomposition. It has high strength and heat resistance that can match beryllium copper, and has the same conductivity as phosphor bronze. Due to the comprehensive properties of strength and conductivity, it can be used for connectors, switches and other purposes.
