Product Description

Product Description

Tin-based babbitt alloy refers to the alloy composed of antimony, copper and other elements with tin as the base, also known as tin-based bearing alloy or tin-based white alloy, is widely used in industry bearing materials.

Material name/grade/classification; 
Common tin-based babbitt alloys include Sn-12Sb-4Cu-10Pb, Sn-11Sb-6Cu, Sn-8Sb-4Cu, Sn-4Sb-4Cu, etc

Microstructure:

The typical structure of tin-based babbitt alloy is that the hard phase particle SnSb is uniformly distributed on the matrix of soft phase α-tin solid solution. The intermetallic compound Cu6Sn5 can prevent specific gravity segregation during solidification

Features: Tin-based babbitt alloy has good wear resistance, good plasticity, good run-in, embedding and bite resistance, good heat resistance and corrosion resistance, suitable for the manufacture of bearing bearing high speed, large pressure and impact load. In order to improve strength and save tin, it is usually cast and used as bushing material to make bimetallic bearing bush

Application

Babbitt alloy is mostly used to manufacture bearings. Bearings find extensive application in the automotive industry. It is present inside engines as well as places where mechanical moving parts need support to operate smoothly. Bearings made using this alloy helps electro-mechanical/mechanical equipment to sustain less frictional damage.
Babbitts with an excess of tin present in its composition are known for its capability to withstand impact. This is why it is often used as the bearing connected to connecting rods and drive shafts.
Babbitt is also used to manufacture bearings used in low-cost electric motors that are used in the distribution of power from a centralized engine.
Babbitt alloy in its wire form is also used in a coating process prominent in the industrial sector known as flame spraying. The purpose of this process is to use Babbitt and coat other objects with a thin layer of the former. It is an affordable and efficient process.
