The right material depends on the gear’s operating conditions:

  • For high loads and durability: Steel or alloy steel is ideal.
  • For corrosion resistance: Stainless steel or bronze is preferred.
  • For lightweight designs: Aluminum or plastics work well.
  • For cost-effective, low-speed applications: Cast iron is a good choice.

Consider factors such as strength, wear resistance, cost, and environmental conditions when selecting materials.
