Technical specifications
Babbit alloys with a low melting point are produced in accordance with GOST 1320−74. They are doped with antimony, copper, zinc, aluminum and other components. Babbits are used for antifriction pouring between rubbing parts of moving parts. Sliding properties of the alloy is given by a special heterogeneous structure — the supporting hard grains are enclosed in a soft tin or lead basis. This reduces friction and wear of rubbing parts to a minimum.
Mechanical properties (temperature 20 ° C)
- · The minimum hardness of HB 13−32,
- · Minimum t ° melting of the substrate ≤ 320 ° C,
- · Increased ductility ≤ 100 ° C HB 9 — 24.
| t ° | σ B | σ T | Density |
| Degrees ° С | N / mm² | N / mm² | g / cm3 |
| 20 | 110−120 | 80−85 | 7.35 |
- σ в — Short-term strength limit
- σ T — Limit of proportionality (yield stress for permanent deformation)
Babbit alloys are not resistant to shock loads and vibrations, which often hinders the operation of moving parts. Low durability allows babbits to be used only in bearings with a strong casing.
