Advantages of tin babbitts
Tin" babbitts have the highest antifriction, running-in, corrosion resistance and thermal conductivity compared to similar alloys. These alloys contain in their soft bases a hard inclusion with the following parameter
- HB 13-32;
- 380-420°C pour;
- increased ductility at 100°C (NV 9 to 24);
- pouring thicknesses from 1 mm.
Disadvantages of B88
- This is the most complex and expensive babbitt alloy.
