Leadedtin Bronze CASTING - LBC

Leaded Tin Bronze is good in terms of pressure resistance and wear resistance, and thus is suitable for bearings. It is good in terms of affinity and thus is used for middle-speed and heavy-load bearings, bearings for big-size engines, back panels of white metals, bushings for high-speed, railroad cars, etc.
