Morphology
The noun is a direct composition of 'white' (a pale/silver-like color) + 'metal' (a metallic substance), so a B1 learner who knows both words can infer it refers to a metal that looks white or silvery. Although the precise technical sense (a tin/lead alloy used for bearings) is specialized and not predictable, the basic descriptive meaning is transparently derivable from the constituents.
Etymology
The noun white metal likely comes from the metal's pale, shiny look, so people called the soft, silvery material white metal. This metal is a mix of metals used as a thin lining in 'bearings' and other parts that rub together, so the phrase now means 'a silvery mix of metals used to stop machine parts from wearing out'.
