Bearing alloy, also known as Bashi alloy, is made of what material?

1, Babbitt is a well-known bearing material, named after the invention of Babbitt by Americans. According to national standards, babbitt alloy can be divided into tin-based alloy and lead-based alloy. The strength and hardness of lead-based alloys are lower than those of tin-based alloys, and the corrosion resistance is also poor. Therefore, when customers use Babbitt alloy, they usually choose tin-based alloy. The representative components of tin-based babbitt alloy are: antimony 3~ 15%, copper 2~6% and cadmium.

2. Although the performance of lead-based alloy is not as good as that of tin-based alloy, many customers still use it because it is economical. Its common brands are ZHPBSB 16- 16-2, ZHP BSB1-1and so on.

3. The structural feature of Babbitt alloy is that hard points and soft particles are evenly distributed on the soft matrix. After running-in, the soft foundation is concave and the hard point is convex, which makes a small gap between the sliding surfaces and becomes an oil storage space and a lubricating oil channel, which is beneficial to reducing friction. The raised hard points play a supporting role and are beneficial to bearing.
