轴承合金是制造轴承用的合金的总称，轴承合金又叫巴氏合金，巴氏合金是一种软基体上分布着硬颗粒相的低熔点轴承合金。有锡基、铅基、镉基三个系列。巴氏合金是广为人知的轴承材料，具有减摩特性的锡基和铅基轴承合金。由美国人巴比特发明而得名，因其呈白色，又称白合金，其应用可以追溯到工业革命时代。
Bearing alloys are the general name of the alloys used in manufacturing bearings. Bearing alloys are also called Babbitt alloys. Babbitt alloys are low melting point bearing alloys with hard particles distributed on soft substrates. There are tin-based, lead-based, cadmium-based three series. Babbitt alloy is a well-known bearing material with antifriction properties of tin-based and lead-based bearing alloys. It was invented by American Babbitt and named for its white color, also known as white alloy. Its application can be traced back to the Industrial Revolution era.
巴氏合金已发展到几十个牌号，是各国广为使用的轴承材料，相应合金牌号的成分十分相近。中国的锡基轴承合金牌号用“Ch”符号表示。牌号前冠以“Z”,表示是铸造合金。如含有Sbll%和 Cu6%的锡基轴承合金牌号为“ZChSnSb11-6”。
Babbitt alloys have been developed to dozens of brands, which are widely used in bearing materials in various countries. The composition of the corresponding alloy brands is very similar. China's tin-based bearing alloy brand is represented by the symbol "Ch". The brand is preceded by "Z", which means casting alloy. For example, the Tin-based bearing alloy with Sbll% and Cu6% is "ZChSnSb11-6".
