Copper-Clad Steel (CCS)

Copper-clad iron generally refers to a composite material with an iron core and a copper outer layer.

Application Principles

1. Turbines (Worm Gears / Turbomachinery Components)

   • Copper-clad steel combines the conductivity of copper with the strength of steel/iron.

   • In turbine or motor components, the copper layer provides good electrical conductivity, while the steel core maintains structural strength.

2. Gear Hobbing

   • Gear hobbing is a machining process for producing gears. When CCS is used as the gear blank material, the outer copper layer offers wear resistance, corrosion protection, and improved machinability, while the steel core provides rigidity and cost advantages.

   • This makes CCS suitable for low-load gears or electrical machinery gears, effectively reducing manufacturing costs.

Key Advantages

• Conductivity + Strength: Suitable for turbine components in motors or small generators that require electrical conductivity.

• Wear resistance & machinability: The copper surface improves cutting stability during hobbing and reduces tool wear.

• Cost-effectiveness: More economical compared to pure copper or full-steel components.

• Corrosion resistance: The copper layer protects the gear surface from oxidation and wear.
