Universal brand babbitt, tin-based alloys, machine tools slider pad ingot alloy, bearing dedicated babbitt, lead Chiba's alloy, babbitt wire, high-tin alloy, bearing alloy, tin-antimony alloy, pewter, antimony trioxide, tin ingots, low melting point, corrosion-resistant alloys, solder, wire, zinc alloy widely used in military, scientific research, electricity, shipbuilding, petrochemical, heavy industry and construction machinery, metal bearings and bushings, but also for slings wire rope reinforcement. Also used in various sealing sleeve and valve, its stable performance, corrosion resistant, seismic compression, rolling bearing can not be replaced.

The main component of the tin-based alloy of tin, lead, antimony, copper. Antimony and copper, to improve the the alloys strength and hardness. In actual use, babbitt can be simply divided into three categories: high-tin alloy, high-lead alloys and master alloys （and tin lead an important share）. In all these alloys lines, antimony and copper as an important alloying element and hardening elements, and its structure is composed of hard intermetallic compound dispersed in a soft matrix.

Universal the Xiji Ba alloy Executive Standard:

GB 340-76 non-ferrous metals and alloy grades representation

GB / T 1174-1992 "cast bearing" （GB 8740-1988 instead of the standard）

Q/HY.100.001.1 bearing alloy enterprise standard （enterprise quality internal control standards）

The Xiji Ba's alloy international technical indicators and use:
