Why Bushings are Made of Bronze
- Wear Resistance: Bronze exhibits excellent wear properties, which is crucial in applications where bushings experience constant friction and movement. This longevity reduces the need for frequent replacements.
- Low Friction: Bronze has low friction characteristics, which helps minimize energy loss and heat generation, ensuring smoother operation of machinery.
- Corrosion Resistance: Unlike steel, bronze is less prone to rust, making it suitable for use in moist or corrosive environments, such as marine applications.
- High Load-Bearing Capacity: Bronze can handle significant loads without deforming, making it ideal for heavy-duty applications where reliability is key.
- Thermal Conductivity: Bronze’s ability to dissipate heat effectively helps prevent overheating, especially in applications with high friction.
- Machinability: Bronze is easy to machine, allowing for precise fabrication to meet specific design requirements.
