WM89 is a lead-free bearing metal/white metal. It serves as a replacement for lead-containing alloys like WM80.

The alloy is characterized by good static compressive strength, high corrosion resistance, excellent plain bearing and emergency running properties, as well as good solderability on Cu-Zn-Sn alloys, cast steel, and cast iron.

Emergency running properties mean that a material can withstand mechanical loads in a plain bearing for a short time, even without lubricant, without failing.

The liquidus temperature is 360 °C (melting temperature). It is recommended to cast the alloy at approx. 390–440 °C. It is easily castable in permanent molds, silicone rubber, and sand.
