Solder & Low-Melting Alloy B560 Type I vs Babbitt Grade 1 (Tin-Base)
Solder & Low-Melting Alloy · grade comparison
Solder & Low-Melting Alloy B560 Type I and Babbitt Grade 1 (Tin-Base) are both solder & low-melting alloy grades. B560 Type I is the stronger of the two: yield strength 32 MPa (4.64 ksi) against 30 MPa (4.35 ksi) for Babbitt Grade 1 (Tin-Base), about 7% more. B560 Type I is the more ductile: elongation 30% versus 8% for Babbitt Grade 1 (Tin-Base), and B560 Type I is harder (25 HB vs 17 HB). Babbitt Grade 1 (Tin-Base) is stiffer (52 GPa vs 45 GPa) and Babbitt Grade 1 (Tin-Base) runs hotter in service (120°C vs 100°C continuous). On the shop floor, Babbitt Grade 1 (Tin-Base) machines more easily (excellent vs very good).
B560 Type IChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
Babbitt Grade 1 (Tin-Base)Choose it when the part sees heat, or when the part is machined in volume.
B560 Type I vs Babbitt Grade 1 (Tin-Base): propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all solder & low-melting alloy grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

B560 Type I vs Babbitt Grade 1 (Tin-Base) — frequently asked
Is B560 Type I stronger than Babbitt Grade 1 (Tin-Base)?
Yes. B560 Type I has a typical yield strength of 32 MPa (4.64 ksi) against 30 MPa (4.35 ksi) for Babbitt Grade 1 (Tin-Base) — about 7% more. Tensile strength is 55 MPa (7.98 ksi) vs 66 MPa (9.57 ksi).
Which is cheaper, B560 Type I or Babbitt Grade 1 (Tin-Base)?
Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, B560 Type I or Babbitt Grade 1 (Tin-Base)?
Babbitt Grade 1 (Tin-Base). Its machinability rates excellent (90/100) against very good (70/100) for B560 Type I; for welding the order is B560 Type I first (poor, 25/100) then Babbitt Grade 1 (Tin-Base) (poor, 20/100).
