Working with Babbitt Grade 3 (Tin-Base) CHILL_CAST

Is Babbitt Grade 3 (Tin-Base) easy to machine?

Bores and scrapes very easily with sharp, high-rake tools and generous flood lubricant; use light feeds to avoid smearing the soft matrix into oil grooves.

Can Babbitt Grade 3 (Tin-Base) be welded?

Not fusion-welded; repair by torch puddling with matching Grade 3 filler after thorough tinning, or replace the lining entirely.

Can Babbitt Grade 3 (Tin-Base) be formed, bent or molded?

Cast only — pour at ~440–470 °C onto a clean, fluxed, hot-tinned steel back and cool directionally to avoid shrinkage voids and bond separation.

What surface finishes work on Babbitt Grade 3 (Tin-Base)?

Finish by boring/scraping to oil-film clearance; no anodizing or plating — protect ingots and linings from oxidation with light oil.

Babbitt Grade 3 (Tin-Base) CHILL_CAST is typically used for automotive engine bearings (older designs), line shaft bearings, light-duty industrial bushings and bearing relining. In short: hardest B23 tin babbitt; lower-cost tin babbitt; highest service temperature, 150 °C.

What is the yield strength of Babbitt Grade 3 (Tin-Base) CHILL_CAST?

Babbitt Grade 3 (Tin-Base) CHILL_CAST has a typical yield strength of 48 MPa (6.96 ksi) and a tensile strength of 78 MPa (11.3 ksi) — stronger than 99% of solder & low-melting alloy grades. Strength varies by condition: see the 4 listed tempers.

Is Babbitt Grade 3 (Tin-Base) CHILL_CAST easy to machine?

Yes — machinability is rated excellent (90/100, better than 95% of solder & low-melting alloy grades). Bores and scrapes very easily with sharp, high-rake tools and generous flood lubricant; use light feeds to avoid smearing the soft matrix into oil grooves.

Can Babbitt Grade 3 (Tin-Base) CHILL_CAST be welded?

Not readily — weldability is rated poor (20/100). Not fusion-welded; repair by torch puddling with matching Grade 3 filler after thorough tinning, or replace the lining entirely.

What surface finishes work on Babbitt Grade 3 (Tin-Base) CHILL_CAST?

Finish by boring/scraping to oil-film clearance; no anodizing or plating — protect ingots and linings from oxidation with light oil.

Can Babbitt Grade 3 (Tin-Base) CHILL_CAST be formed, bent or molded?

Cast only — pour at ~440–470 °C onto a clean, fluxed, hot-tinned steel back and cool directionally to avoid shrinkage voids and bond separation.

What is the maximum service temperature of Babbitt Grade 3 (Tin-Base) CHILL_CAST?

Babbitt Grade 3 (Tin-Base) CHILL_CAST is rated for continuous use to about 150°C (302 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
