Arts: What Are The Properties Of Lead-based Babba Alloys?

Apr 15, 2018

In industrial production, it is usually required to use babbitt, which is mainly invented by American inventor Babbitt. Since it was invented, it has taken a certain advantage in industrial production and has become more widely used. However, with the improvement of industrial production technology, the stronger the type of babbitt, more and more, different industries in the use of babbitt, the effect is completely different. According to Arts, for some companies with high requirements for carrying capacity, lead-based babbitt alloys are needed for processing and manufacturing, but when the alloys are used, they need to have major performance. Have some understanding.

        According to Arts, babbitt alloys are mainly used in bearing bushes, bearings, bushings, and bushings for large-scale machine spindles. Such as: cement machinery, steel machinery, chemical machinery, paper machinery, petroleum machinery, shipbuilding machinery, compression machinery, coal mining machinery, mineral processing equipment, etc., can also be used on large-scale machine tools instead of brass, the effect is also very good.

        Lead-based babbitt alloys have high compressive strength

        When lead-based babbitt alloys are used, they can carry greater pressure and their use is relatively extensive. At the same time, the use of lead-based babbitt alloys can ensure production safety and better protect the safety of construction personnel. . According to Arts, in addition to manufacturing sliding bearings, Babba alloy is often used as a bearing bush by spraying its wire or powder on a steel substrate due to its soft texture and low strength. To prevent segregation of components and grain refinement, a small amount of arsenic is often added.

        Arts says lead-based babbitt alloys have high fatigue resistance

        Lead-based alloy two. The latter contains 10% to 20% of antimony, and 5% to 15% of tin. To prevent segregation of components and grain refinement, a small amount of arsenic is often added. Lead-based alloys have lower strength and hardness than tin-based alloys and have poor corrosion resistance. For workers in the industrial production industry, they all know that the alloys have the highest load-bearing capacity when used and they also have some fatigue. Arts said that, in fact, the fatigue resistance of alloys mainly refers to the use time of the alloy. The fatigue resistance of lead-based babbitt alloy is relatively high, so the use of this alloy is more extensive.

        Arts says lead-based babbitt alloys have good antifriction properties

        In addition to the manufacture of plain bearings, babbitt alloys are often used as bearing bushes by spraying their wires or powder onto steel or other substrates due to their soft texture and low strength. To prevent segregation of components and grain refinement, a small amount of arsenic is often added. The friction coefficient of lead-based babbitt alloy is relatively small, so when used, the friction generated with other components will be small, so that the components can be better protected, and the use time of the components can be prolonged. The corresponding production costs.

        Arts said that of course, lead-based babbitt metal also has a very important performance, has a good running and thermal conductivity, but also has a good corrosion resistance.
