The correct answer is phosphor bronze.

Phosphor bronze is a copper-tin alloy (typically 10-12% Sn) with a small amount of phosphorus (0.1-0.5% P). It is suitable for bearings subjected to heavy loads due to its:

- High compressive strength
- High wear resistance
- Good fatigue strength
- Ability to withstand high loads and stresses

Phosphor bronze is often used for:

- Heavy-duty bearings.
- Bushings and sleeves.
- Gears and pinions.
- Axle bearings.

The other options are not correct because:

- Silicon bronze is a copper-silicon alloy, which is not as strong as phosphor bronze for heavy-load applications.
- White metal (Babbit metal) is a tin-based alloy, which is softer and more prone to wear than phosphor bronze.
- Monel metal is a nickel-copper alloy, which is more corrosion-resistant but not as strong as phosphor bronze for heavy-load applications.

The phosphor bronze is a popular choice for heavy-duty bearings due to its excellent mechanical properties and ability to withstand high loads.

Heavy - White metal.
Light - Phosphorus.

The white metal is for heavy loads.

Phosphors bronze for lighter load and silicon bronze for heavy load.

Phospor bronze is for Lighter loads.

It should be phosphor Bronze.
