Phosphorous Bronze Bushing

Phosphor bronze has higher corrosion resistance, is resistant to wear and tear, and does not spark on impact. For medium speed, heavy load bearings, working at a maximum temperature of 250 ℃. With self-aligning, insensitive to deflection, shaft bearing force uniform high bearing capacity, can be subject to radial load at the same time, self-lubrication without maintenance and other characteristics. Tin-phosphor bronze is an alloy copper, with good electrical conductivity, not easy to heat, to ensure the safety of the same time with a strong fatigue resistance.

 

Description

Phosphor bronze is an alloy of copper with tin and phosphorus, which has a hard texture and can be made into bearings. P is used to remove oxygen from pure copper and bronze (Cu-Sn) and a small amount of P remains, as well as Cu alloy with 1% P added to improve mechanical properties (toughness, elasticity, wear resistance, corrosion resistance). It is mainly used as wear-resistant parts and elastic components.

Properties of Phosphorous Bronze

Phosphorous bronze, also known as tin bronze, is an alloy made from copper, tin, and phosphorous. These elements combine to produce a strong, corrosion-resistant, and wear-resistant material. Phosphorous bronze has a low coefficient of friction, making it perfect for applications that require reduced friction and increased load capacity.

Phosphorous Bronze Bushing Properties And Characteristics

  • Strength and resilience – phosphor bronze is a fatigue-resistant alloy. It holds up exceptionally well to wear. The inclusion of tin is what gives photo bronze its added strength, and phosphorus gives it a greater wear resistance.
  • Corrosion resistance – this alloy is commonly used in applications where it will have exposure to corrosive chemicals and/or physical elements.
  • Electrical conductivity – the use of phos bronze in electrical components is perhaps its most well-known application.
  • Excellent elasticity – the fine grain size of this alloy enables the material to have a greater degree of spring back.

Types of Phosphorous Bronze Bushings

There are various types of phosphorous bronze bushings available, including:

Solid bushings: A one-piece bushing with no moving parts
Split bushings: A two-piece bushing designed for easy installation and removal
Flanged bushings: A bushing with an integrated flange for additional support

Advantages of Phosphorous Bronze Bushings

Corrosion Resistance

Phosphorous bronze bushings offer excellent corrosion resistance, making them ideal for use in harsh environments, such as marine and chemical applications.

Wear Resistance

The alloy’s high strength and hardness make phosphorous bronze bushings extremely wear-resistant, which is crucial for applications with high loads and frequent movement.

Reduced Friction

Phosphorous bronze bushings have a low coefficient of friction, which helps to reduce friction between moving parts, leading to increased efficiency and reduced wear.

Increased Load Capacity

Phosphorous bronze bushings can withstand higher loads compared to other materials, making them suitable for applications with heavy or continuous loading.

Selecting the Right Phosphorous Bronze Bushing

Considerations

When selecting a phosphorous bronze bushing, it is essential to consider factors such as the operating environment, load capacity, speed, and temperature. Additionally, the type of lubrication and the size and shape of the bushing should be taken into account.

Tips for Choosing

Determine the load and speed requirements for your application
Assess the operating environment and potential exposure to corrosive elements
Select the appropriate type of phosphorous bronze bushing based on your application requirements
Choose the right size and shape to ensure a proper fit and smooth operation
Consider using a lubricant to further reduce friction and extend the life of the bushing

Phosphorous Bronze Bushing In Automotive Manufacturing

Phosphor bronze is the most widely used bushing material in automobile manufacturing. It is widely used in connecting rod bushings of air compressors, refrigerators and internal combustion engines, cross pin bushings, piston pin bushings, camshaft bushings, guide Wheel bracket bushings, gearbox bushings, etc. It is characterized by high hardness, good wear resistance, low friction coefficient, good impact toughness, high allowable specific pressure and limit linear speed, and good manufacturability. Phosphorus in phosphor bronze can prevent extremely hard and brittle SnO2 from being produced in the alloy, and has a protective effect on the journal. Therefore, the use of phosphor bronze as the bushing material is beneficial to prolong the mechanical life.
