Tin combines with a number of metals to form eutectics. These alloys exhibit low melting points, low strength and hardness, and good anticorrosive properties; certain tin alloys also have low coefficients of friction. Tin alloys are primarily used for tinning and as fusible alloys, bearing metals, and solders.
