Tin foil Babbitt B-83

Tin foil Babbitt B-83

As is known,

In our time in industry and

Construction began to be widely used

Various metal alloys that

Most well-suited to certain

Conditions. Such an alloy is babbit

Is an alloy based on tin or zinc.

There are many different

Brands of babbits, among which

Tin babbitt

Widespread Babbit B83). What

Features of a tin babbit?

At first

Should be given a characteristic of tin -

Metal, which is used as a

Bases for the tin babbit. Tin -

Metal of silvery-white color, possessing

Good plasticity, which is

Air has a property gradually

Covered with a protective oxide layer. In

The combustion time from it forms a white

Powder - tin oxide SnO2, used

As a polishing agent. Tin

Used to cover other metals

And protect them from corrosion, it is made of

White tin for cans. Besides

In addition to many alloys,

There is tin (for example,

Low-temperature solders, printing,



Tin-based products such as

Babbit B83, B88, B83C, SAE11, SAE12, ASTM, are used,

When the antifriction material needs

In high viscosity and minimal

Coefficient of friction. Tin Babbit,

In contrast to lead, has more

High corrosion resistance,

Wear resistance and thermal conductivity, and

Also a lower coefficient of linear


All babbits

Have a significant drawback -

They have low resistance to fatigue,

Which leads to a decrease in efficiency

Bearings. The same can be said about

And about the tin babbit B83. Having a small

Strength, tin babbit can

Successfully applied only in bearings,

Which have a durable cast iron, steel

Or a bronze case. Usually,

Production of thin-walled bearing

Car engine inserts

By punching out

Bimetallic tape, which is obtained

On the line of continuous pouring. Term

Bearings depends on the

Thickness of the babbitt alloy layer, which

Poured on a steel liner. When

A decrease in the thickness of the babbitt layer,

Longer working time



Rule, tin babbit

B-83 is used in engineering for


Bearings that work with

High speeds and loads of medium

Values; Bearings of turbines, crosshead,

Crankshaft and frame bearings

Low-speed diesels, support bearings

Ridging shafts.
