![]() Tin based babbitt alloy is based on tin, adding a small amount of antimony and copper. Types of babbitt alloysīabbitt alloys can be divided into tin based and lead based: Tin-base babbitt metal Copper based and aluminum based bearing alloys are commonly used in hard matrix and soft texture. The concave convex gap between the soft substrate and the hard point is also conducive to the storage of lubricating oil.īabbitt alloy belongs to hard point structure with soft matrix. Soft base can bear impact and vibration, good running in hard point can reduce the contact surface with the shaft, reduce the friction coefficient, reduce wear, good wear resistance. There is strong friction between sliding bearing and high-speed and heavy-duty shaft, so the microstructure of sliding bearing alloy is required to have two kinds: hard point on soft matrix and soft point on hard matrix. Antimony and copper are used to improve the strength and hardness of the alloy. The main composition of babbitt alloy is tin, lead, antimony and copper. Because of its white, also known as white alloy. Babbitt metal is a tin based and lead based bearing alloy with antifriction properties, which was invented by Babbitt. ![]()
