White Babbitt Bearing Metals

JAYTEE alloys is a mass manufacturer and supplier of White metal. It is also known as bearing metal or Babbitt metal. It is a soft, white, non-ferrous alloy used in the construction of bearings and other machinery components. It was invented in the early 19th century by Isaac Babbitt and is commonly used in applications where low friction and high wear resistance are required. The composition of white metal can vary, but it typically consists of tin, antimony, and copper.

Here are the details of the composition and properties of white metal:

Composition:

The typical composition of white metal, also known as Babbitt metal, can vary, but it generally consists of:

Tin (Sn): 80% to 90%

Antimony (Sb): 7% to 10%

Copper (Cu): 1% to 3%

Other elements such as lead and zinc may also be added in smaller amounts to modify the properties of the alloy.

Properties:

Low Friction: White metal has a low coefficient of friction, making it ideal for use in bearings where smooth, low-wear operation is required.

High Wear Resistance: It offers excellent resistance to wear, even under heavy loads and at high speeds.

Conformability: White metal has the ability to conform to minor imperfections in the shaft or housing, providing a better fit and reducing the risk of damage.

Corrosion Resistance: It has good corrosion resistance, which helps to prolong the life of the bearings and other components made from this alloy.

Softness: The softness of white metal helps to minimize damage to the mating surfaces of the bearing and the shaft.

Melting Point: The melting point of white metal typically ranges from 250° to 300°, depending on the exact composition of the alloy.

Machinability: White metal is relatively soft and can be machined easily, making it suitable for applications where precise dimensions and tight tolerances are required.

Maintenance: Regular maintenance and lubrication are essential to ensure the proper functioning and longevity of bearings and other components made from white metal. Over time, the white metal may wear out, requiring replacement or re-lining of the bearings.

Use:

White metal or Babbitt metal is commonly used in the following applications:

Bearings: It is widely used in the construction of plain bearings, thrust bearings, and journal bearings in various types of machinery, including engines, turbines, and industrial equipment.

Slide Plates: It is used in slide plates and other components where low friction and high wear resistance are required.

Solders: Due to its low melting point, white metal is also used in soldering applications.

Seals and Gaskets: It is used in the manufacture of seals and gaskets due to its ability to conform to irregular surfaces.

In conclusion white metal or Babbitt metal is a versatile and widely used material in the manufacturing of bearings and other machinery components due to its excellent friction and wear properties.
