Cylindrical brushes are preferred for generators and specialized machinery requiring compact and precise electrical contact. Custom-shaped brushes cater to niche applications where design specifications demand tailored performance.

In terms of material, carbon brushes are primarily classified into graphite, metal-graphite, and resin-bonded brushes. Graphite brushes dominate due to excellent conductivity, durability, and suitability for high-speed motors. Metal-graphite brushes are preferred in heavy-duty industrial motors and generators where higher electrical conductivity is required, while resin-bonded brushes are used in specialized electrical equipment with low friction and minimal wear requirements.

By end-use industry, the market encompasses automotive, industrial machinery, renewable energy, railways, and consumer electronics. The automotive sector is the largest end-user due to the rising production of electric vehicles and hybrid vehicles. Industrial machinery applications, including mining, material handling, and manufacturing, demand carbon brushes to ensure seamless operations and reduce maintenance costs. Renewable energy applications, such as wind turbines and hydroelectric generators, require reliable carbon brushes to maintain uninterrupted power generation.

By application, carbon brushes are used in motors, generators, and alternators. Motors represent the largest application segment, driven by their extensive use in electric vehicles, industrial machines, and household appliances. Generators and alternators are also significant applications, particularly in renewable energy systems and industrial power backup solutions.
