Standard Specification for White Metal Bearing Alloys (Known Commercially as "Babbitt Metal")

ABSTRACT
This specification deals with eight typical white metal bearing alloys, in bar or ingot form, known commercially as "Babbitt metal." Covered in this specification are tin-based alloys, namely, UNS-L13910 (alloy no. 1), UNS-L13890 (alloy no. 2), UNS-L13840 (alloy no. 3), and UNS-L13870 (alloy no. 11); and lead-based alloys, namely, UNS-L53585 (alloy no. 7), UNS-L53565 (alloy no. 8), UNS-L53346 (alloy no. 13), and UNS-L53620 (alloy no. 15). Materials shall be manufactured in accordance with such practice as to obtain the chemical composition, weight, and dimensions as prescribed herein.
SCOPE
1.1 This specification covers eight typical white metal bearing alloys, in bar or ingot form, known commercially as “babbitt metal.” The alloys are specified, covering the range commercially used, and are designated by the alloy numbers shown in Table 1.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to become familiar with all hazards including those identified in the appropriate Material Safety Data Sheet (MSDS) for this product/material as provided by the manufacturer, to establish appropriate safety and health practices, and determine the applicability of regulatory limitations prior to use.
