==Introduction==
Many different grades of Babbitt were sold and marketed over the years by many different companies with some still being commercially available today.  With so many types being manufactured through the years, it is not uncommon to find vintage ingots of Babbitt at garage sales, hardware stores, on-line auctions and various other sources.  Because of this, this guide will show pictures and give details on Babbitt ingots commonly found.  The following guide is classified by manufacturer.  As information on the composition of different brands becomes available to us, we will add them to this guide.


==American Smelting and Refining Company==
The American Smelting And Refining Company was founded in 1899 by Henry H. Rogers, William Rockefeller, Adolph Lewisohn and Leonard Lewisohn. In 1901 Meyer Guggenheim and his sons took over the company. The company changed its name to [^http://www.asarco.com/|ASARCO] Incorporated in 1975 and has operated under that name ever since. 


The companies primary business has always been copper mining and refining but has also interest in lead processing.  Upon the many products manufactured by American Smelting and Refining Company, various grades of Babbitt were included.

==Magnolia Metal Corporation==
[^http://www.magnoliabronze.com/|Magnolia Metal Corporation] began business in 1886 with a technical innovation in the then new bearing industry: the invention of lead-based babbitt metal. Less expensive than tin-based babbitt, "Magnolia Anti-Friction" was soon being shipped around the world. Over 100 years later, babbitt products comprise only 1% of Magnolia Metals sales, but the company still manufacturers several grades of Babbitt. Customers can still purchase large quantities of these Babbitt today metals directly from Magnolia.  


===Magnolia Anti-Friction Metal===
[|][imageauto|Magnolia Anti-Friction Metal|{UP}Babbitt/MM-Magnolia.JPG]Sold by the [^http://www.magnoliabronze.com/|Magnolia Metal Corporation], Magnolia Anti-Friction Metal is still available for purchase today. Introduced in 1886, Magnolia Metal (as it was commonly referred to) was advertised as "the best bearing material known to man and far superior than any other Babbitt." While there is no doubt that Magnolia Metal has it's applications and does generally perform well, it also has some limitations. Magnolia Anti-Friction Metal is a primarily lead based material but with the addition of graphite for to make it somewhat self lubricating.

===Adamant Super-Genuine Babbitt===
[|][imageauto|Adamant Super-Genuine Babbitt|{UP}Babbitt/MM-Adamant.JPG]Sold by the [^http://www.magnoliabronze.com/|Magnolia Metal Corporation], Adamant Super-Genuine Babbitt is still available for purchase today. Exact composition is not know but this is a tin based babbitt and suspected to be a similar formula as original Babbitt (probably ASTM B-23 Grade 2).  This product would be preferred over Magnolia Anti-Friction Metal for most high speed applications.


According to the Magnolia Metal Corporation, Adamant Super Genuine Babbitt is "a genuine babbitt metal alloyed especially for malleability, strength and toughness. Will not crack or chip even when subjected to extremely severe shock loads. Easy to pour, conforms well to the shell. Typical Applications... Internal combustion engines... trap rock crushers... sifter machinery."


Pouring temperature for Adamant Super-Genuine Metal is 775-825 degrees F.


==National Lead Company==
The National Lead Company, renamed [^http://www.nl-ind.com/|NL Industries] in 1971, can trace its roots as far back to 1772 in Philadelphia. In 1891, several lead manufacturers banded together and incorporated as the National Lead Company. The company has been well known for its white-lead paints, sold since 1907 under the Dutch Boy label. Of the companies many products, bearing metals are included. Ingots of various types are commonly found today with the "Dutch Boy" trade mark cast into the face of the ingot.


===Bearing Metal===
This brand is simply branded "Bearing Metal."  Exact composition is not known but it suspected to be a basic lead based babbitt.


===Genuine Babbitt Metal===
[|][imageauto|Genuine Babbitt|{UP}Babbitt/NL-Babbitt.JPG]A tin based babbitt which would be more appropriate for high speed applications. While exact composition is not known, it is probably a ASTM B-23 Grade 2 Babbitt.


===Perfection Anti-Friction Metal===
Another brand of babbitt metal made by National Lead.  Composition of this metal is also unknown but probably a mid-grade product with more tin than the basic "Bearing Metal" but not enough to call it a true "Genuine Babbitt Metal."


===Phoenix Metal===
[|][imageauto|Phoenix Metal|{UP}Babbitt/NL-Phoenex.JPG]Unknown composition but appears to be a lead based Babbitt.




==United American Metals Corporation==
[^http://www.uamet.com/|United American Metals Corporation] was founded in 1889 by the Muscat Family in Brooklyn, N.Y. Originally, the company specialized in lead based metals to make type for the printing industry.  


During the Second World War, the primary focus switched from lead type to Babbitt for the Marine industry and the general trade as part of the war effort. During this time, a new plant was opened in Tyler, Texas plant. Highest priority for use of scarce materials such as Tin and Antimony was given UAM by the War Production Board.


After WWII, the company expanded their product line to many other types of specialty metals but still makes several babbitt metals to this day.


More information on this company can be found in this link to some old literature concerning the products of the [{UP}%2fBabbitt%2fUnitedAmericanMetals.pdf|United American Metals Corporation].


===Stonewall Babbitt===
[|][imageauto|Stonewall Babbitt|{UP}Babbitt/UAM-Stonewall.JPG][|][imageauto|Stonewall Babbitt|{UP}Babbitt/stonewall2.jpg]Made by the [^http://www.uamet.com/|United American Metals Corporation], Stonewall Babbitt has been around for many years and is still being sold today through industrial supply houses such as [^http://www.mcmaster.com|McMaster-Carr]. This is a Lead Based Babbitt is among the least expensive babbitt that you can buy.

While this material would work fine for light duty and low speed applications, for just a little more money, you can get a much better quality material. Probably best to shy away from for most machinery applications.


Pouring Temperature is 650 degrees F.




===Government Genuine Babbitt Metal===
[|][imageauto|Government Genuine Babbitt|{UP}Babbitt/UAM-GenuineBabbitt.jpg][|][imageauto|Government Genuine|{UP}Babbitt/govgenuine.jpg]Also made by the [^http://www.uamet.com/|United American Metals Corporation], this tin based Babbitt is advertised as the highest grade of Babbitt metal made by that company.
