Grade LTB 1 & LTB 2 are meant for general castings and have fair strength and good machining properties. They are used in Valve fittings & pump castings. Grade LTB 3 is suitable for High speed & heavy pressure bearings. Grade LTB 4 is used for General Castings in moderate pressure applications and general-purpose bearing metal. Grade LTB 5 is used for hard or moderately hard shafts with loads and speeds moderate or low with rather less adequate lubrication and alignment. Grade LTB 6 is used for bearing under light loads and high Speeds.
