• Babbitt Powder / Wire Description:

a) Babbitt metal, also called white metal, is an alloy used to provide the bearing surface in a plain bearing. It was invented in 1839 by Isaac Babbitt in Taunton, Massachusetts, USA. The term is used today to describe a series of alloys used as a bearing metal. Babbitt metal is characterized by its resistance to galling.

b) There are two types of lead babbitts: a) alloys of lead, tin, antimony and in many instances arsenic; and b) alloys of lead, calcium, tin and one or more of the alkaline earth elements

c) Babbitting is a process by which softer metals (basically tin/lead combinations) are bonded chemically or mechanically to a shell or stiffener, which supports the weight and torsion of a rotating, oscillating or sliding shaft.
