temperature heavy loads. The base metal should be tinned with pure tin solder
paint.
WM2
This alloy is recommended for axle box lining for all locomotive applications. Good
bonding properties. The base metal may be tinned with tin lead solder paint.
WM3
Tin Lead based alloy for use in less critical applications. The base metal may be
tinned with tin lead solder paint.
WM4
High Lead based alloy recommended for low stress, non critical bearing applications
such as shafts, trunions and similar linkages. The base metal may be tinned with tin
lead solder paint.
