Short answer: Gears use alloy and case-hardened steel for spur, helical and bevel drives where strength and wear matter, bronze worms on steel for low-friction reduction, steel with polymer backing for quiet runs, and cast iron or steel for large ring gears, all chosen for strength, toughness, wear and noise control under load.
At a Glance
What Gears Need
Strength, wear and toughness lead the choice, with the basis in our Metal Strength Comparison and fatigue notes in our Metal Fatigue Guide; hardness detail is in our Hardness Comparison Guide.
Material by Type
Spur and helical gears use alloy steel, bevel gears use case-hardened steel, and worms use bronze on steel, with the cast basis in our Cast Iron vs Steel Guide and the brass basis in our Brass Supplier.
Wärmebehandlung
Gears are carburized, nitrided or through-hardened for a hard case and tough core, with methods in our Heat Treatment Guide und Nitriding vs Carburizing Guide; machining is in our Machining Guide.
Quality and Sourcing
Gear quality is checked by inspection, with methods in our Quality Inspection Guide; buyers confirm grade via our Mill Test Certificate Guide and pack per our Export Packing Guide.
