Casting Metals
Melt and pour these alloys into molds to create metal parts and prototypes.
Lead-base babbitt is a soft alloy. Use it to cast light-load bearings. It has superior antifriction properties.
Lead-base coppered babbitt is able to withstand shock and vibration and requires less lubrication than other types of babbitt. Use it to cast bearings for low-speed, heavy-load applications.
Tin-base babbitt is used to cast bearings for high-speed, high-wear applications and can withstand heavy, sustained loads. It has a higher melting temperature than lead-base babbitt.
