Notes:

a) No Zinc or Aluminium (Aluminum) used in any of these compositions
b) Babbitt No10: This Babbitt is very fluid and may be used for Bronze-backed bearings,
particularly for thin linings such as are used for aircraft engines. It is also used for die-castings.
c) Babbitt No11: A rather hard babbitt which may be used for lining connecting-rod and shaft bearings which are subject to heavy pressures.
Its 'wiping' tendency is very slight. It is also suitable for die-castings.
d) Babbitt No12: A relatively cheap babbitt and is intended for bearings subjected to moderate pressures. It is also suitable for die-castings.
e) Babbitt No's 13 & 14: Cheap babbitt metals which serve successfully where the bearings are large and the service light.
They should not be used as a substitute for a babbitt with high tin content. Both are also suitable for die-castings.

Notes:

* Phosphor Bronze. Excellent for heavy loads and severe usage.
** Semi-Plastic Bronze. Soft Bronze with good anti-friction qualities.
*** Leaded Gun Metal. A general utility bronze, especially for bushings carrying heavy loads.
**** A maximum of 0.60% Lead is permissible in finished-Steel or Bronze-backed bearings provided
a tin-lead solder has been used in bonding the bearing material to the backing metal.

Notes:

**** Railway Journal Bearings according to standard specifications of the Association of American Railroads as follows:-
Brass Backing: Lead 15% to 22%, Tin 5% to 7%, Max impurities including Zinc 3%, excluding Zinc 1%, balance Copper.
Lining: Tin as specified in table, Antimony not less than 8%, Tin & Antimony 10% to 14%, Arsenic max 0.2%,
Copper max 0.5%, SUM of Tin, Antimony, Lead & Arsenic Min 99.25%, remainder MAX 0.75%
Last 5 specifications are ASTM standard grade spec's for Babbitt Metal. The cheaper grades have relatively high percentages of Lead.
