Key features:
High lead content of this alloy gives it the ability to tolerate interrupted lubrication. The lead also alows dirt particles to become embedded harmlessly in the bearing’s surface. Also has good corrosion resistance.
Full alloy description:
A.W. Fraser Alloy 938 is a high leaded tin bronze bearing and bushing material conforming to the requirements of UNS C93800.
Alloy 938 is most suitable in applications where shaft alignment or shaft wear is a problem.
The high lead content of this alloy gives it the ability to tolerate interrupted lubrication. The lead also alows dirt particles to become embedded harmlessly in the bearing’s surface.
Alloy 938 has good corrosion resistance.
The composition of A.W. Fraser alloy 938 is strictly controlled as are the casting conditions to ensure even distribution of the lead throughout the casting.
Machinability Rating: n/a
