Standard
AMS4275E
This specification covers an aluminum alloy in the form of permanent mold castings.

Standard
AMS4631F
This specification covers one type of aluminum bronze in the form of rods, bars, forgings, and forging stock.

Standard
AMS4751D
This specification covers a tin-lead alloy in the form of bars, ingots, pellets, ribbon, and round wire. This solder has been used typically for effecting joints in electrical and electronic circuits where the reliability of the joint requires good control of the purity of the solder, but usage is not limited to such applications.

AMS4625H
This specification covers one type of bronze in the form of bars and rods of any size, and tubing over 1.00 inches (25.4 mm) in nominal outer diameter (see 8.5).

AMS3678/14A
This specification covers a polytetrafluoroethylene (PTFE) resin filled with 40% bronze powder in the form of extruded or molded rods or tubes which are sintered after molding or, in the case of extrusions, sintered during the extrusion process.

Standard
AMS3678/6B
This specification covers a polytetrafluoroethylene (PTFE) resin filled with 60% bronze powder in the form of extruded or molded rods or tubes which are sintered after molding or, in the case of extrusions, sintered during the extrusion process.

This Bulletin provides a brief description of tin whisker formation and describes various methods recommended by government and industry to reduce the risk of tin whisker-induced failures in electronic hardware. It is not a mandate nor does it contain any requirements. A tin whisker is a single crystal that emerges from tin-finished surfaces. Tin whiskers can pose a serious reliability risk to electronic assemblies that have pure tin finish. The general risks fall into several categories: [1, 2, 3, 8, 16] Short Circuits: The whisker can create a short circuit, either by 1) growing from an area at one potential to an area at another or 2) breaking free and later bridging these areas. In some cases, these shorts may be permanent and cause catastrophic system failures. A transient short may result if the available current exceeds the fusing current of the whisker, and the whisker can fuse open.

Compositions apply to the finished bearing or bearing lining, not necessarily to the alloy at an intermediate processing stage. All values not given as ranges are maxima. (See Tables 1 through 5.)

J459_199110
The bearing performance of steel backed half bearings, bushings, and washers is dependent on the properties and thickness of the lining alloy, the strength and dimensional stability of the steel backing (usually SAE 1010) and the strength of the bond between the lining alloy and the backing. This SAE Information Report is primarily concerned with the properties of the lining alloys used in automotive applications, in particular, the crankshaft bearings of the internal combustion engine.
