What are the main characteristics of tungsten carbide bushings?

1. Wear Resistance

Tungsten carbide bushings exhibit excellent wear resistance. The internal structure of these bushings is dense, without any looseness or porosity, giving them a bright appearance and a unique color. Most importantly, they possess relatively high hardness.

2. Corrosion Resistance

Another notable feature of tungsten carbide bushings is their good corrosion resistance. They are primarily used in atmospheric and freshwater environments, which are relatively benign. During use, copper bushings rarely experience seizing. The corrosion resistance of copper bushings is particularly evident when exposed to chemical elements such as dilute sulfuric acid, hydrochloric acid, and fatty acids. This excellent corrosion resistance is due to their unique characteristics and superior performance. Even without lubricants or in the presence of aqueous lubricants, they can function normally, maintaining good slidability and self-lubrication properties.

3. Compression Resistance

Tungsten carbide bushings also demonstrate impressive compression resistance. They can withstand significant surface pressures and effectively bear the side pressures exerted by bearings, allowing them to operate under high load conditions.
