Lead Babbitt, refers to several lead based alloys are also known as to as Babbitt metal, lead Babbitt or bearing metal, and are used in the bearing surface on bearings. Lead seals are used in several applications where the properties of lead are advantageous
Cambridge, MA December 30, 2016 – Nuclead a leading manufacturer and distributor of custom and standard lead products for research, industry and consumers announces the delivery of several orders of lead Babbitt and lead seals to manufacturers in the USA.
Lead Babbitt
Several lead based alloys are referred to as Babbitt metal, lead Babbitt or bearing metal, and are used in the bearing surface on bearing. The name Babbitt is named for its inventor Isaac Babbitt from Taunton, Massachusetts, USA, who first formulated a tin based bearing alloy in 1839. Today a several varieties lead based Babbitt alloys exist, including:
- Lead antimony (80% lead, 15% antimony, 5% tin)
- Lead Tin (75% lead, 10% tin)
- Copper-lead based Babbitt (76% copper, 24% lead)
- Copper-lead-tin based Babbitt composed of (67% copper, 28% tin, 5% lead)
Originally used as a cast in place bulk bearing material, it is now more commonly used as a thin surface layer in a complex, multi metal structure.
Nuclead can make any custom babbitt. Supply us with your specifications and we’ll fabricate and certify to your special needs.

Lead Seals
Lead Seals are used plastic and other metal seals are not appropriate. These applications include cryogenics, low strength flanges, optical components and vacuum. Lead seals are useful in conditions such as high temperatures and pressures, cryogenic conditions, chemical resistance, prevention of outgassing, radiation, gas permeability and hard vacuum duty.
Lead (Pb) has similar properties to Indium, although it is slightly harder with slightly higher temperature capabilities.
Nuclead has standard and special grades of lead washers, lead seals, lead shims and lead spacers available.
Here are some of Nuclead’s orders for Lead Seals
- CNC machine per customer supplied blueprints…hundreds of pure lead seals. Sold to a bearing and seal OEM for a special item that they purchase from Nuclead on a regular basis.
