Some other bearing materials find extensive use for which production volume is less well defined. EiHed plastics such as nylon, acetal resin, PTEE, and phenoHcs are formed and molded into bearings in a wide variety of mechanical stmctures. Tin, lead, and bronze alloys are used for oil-film bearings in heavy industrial and power generating equipment, frequently in custom bearings manufactured directly as machine components.

Properties of copper—tin—lead alloys are Hsted in Table 10. The members of the tin bronze alloy group are cast using the centrifugal, continuous, permanent, plaster, and sand molding methods. Leaded tin—bronze alloys have minimum tensile strengths of 234—248 MPa (34,000—36,000 psi) as cast in sand molds, whereas the minimum tensile strengths for high leaded tin—bronze alloys are 138—207 MPa (20,000—30,000). The values are based on measurement of test bars cast in sand molds.

One of several types of high-chloride resistant, copper/tin alloys (e.g. 90% Cu + 10% Sn), usually 11% Sn maximum and also containing small amounts of Zn and P. Also bronze alloys, whereby Sn is replaced by Al, Si, or Be. 

The main alloys of copper are the brasses, alloyed with zinc, and the bronzes, alloyed with tin. Other, so-called bronzes are the aluminium bronzes and the silicon bronzes. 

Since tin is much less volatile than zinc, bronzes are more versatile than brasses. The low volatility of tin allowed bronze alloys to be cast and forged into various shapes, including large bells. These formed the basis of the first large scale communication systems. Every settlement had its own bell tower for communicating with its residents, and with other settlements.

Another interesting bit of history regarding tin came around 500 BCE, when the tin mines of the eastern Mediterranean region were depleted. This created a problem because tin, a rather rare metal, was very necessary to make the hardened bronze alloy for weapons and tools. This also is thought to be the first time in human history that a mineral was depleted in a region due to mining.
