The production material of cast iron pulley is mainly various types of cast iron, but according to the specific needs and application scenarios, different types of cast iron will be chosen to use.

1. Gray cast iron: with high shock resistance and good wear resistance, suitable for most industrial applications

2. Ductile iron: suitable for applications requiring high stress and impact, such as heavy machinery and equipment

3. Malleable cast iron: Often used in parts that require certain plasticity and toughness, such as some special purpose pulleys

4. Alloy cast iron: according to needs, can improve corrosion resistance, high temperature resistance or strength, applied to specific industrial needs.

When choosing the right groove shape for a cast iron pulley, the following factors need to be considered to ensure that the pulley can work effectively and extend its service life:

1. Rope and belt type
Wire rope: Select V-shaped groove.

Fiber or braided rope: Choose U-shaped groove.

Cable: Select round or semi-round groove.

Multi-wedge belt (multi-V belt) : Select trapezoidal groove.

2. Application scenario
Heavy machinery equipment: Choose V-shaped or trapezoidal grooves because these grooves can withstand high loads and stresses.

Light lifting equipment: Choose U-shaped groove, suitable for softer ropes, reduce wear.

Elevator and cable car systems: Select circular or semi-circular grooves to evenly distribute stress and reduce damage to the cable.
