Applications
For other aluminum alloy ASTM B26/B26M 852.0, typical cast components in this material family include bearings, bushings, connecting-rod bearings and crankcase bearings. Applications include diesel engines and industrial machinery. Some sand-cast grades are also used for larger rolling-mill bearings. These are lubricated sliding-contact duties, with the alloy and casting route selected for the actual shaft, lubricant and bearing design.
