Solder & Low-Melting Alloy Babbitt Grade 3 (Tin-Base) vs Type 2 Sheet Pewter
Solder & Low-Melting Alloy · grade comparison
Solder & Low-Melting Alloy Babbitt Grade 3 (Tin-Base) and Type 2 Sheet Pewter are both solder & low-melting alloy grades. Both yield at about 45 MPa — strength does not separate them. Type 2 Sheet Pewter is the more ductile: elongation 25% versus 3% for Babbitt Grade 3 (Tin-Base), and Babbitt Grade 3 (Tin-Base) is harder (27 HB vs 25 HB). Babbitt Grade 3 (Tin-Base) is stiffer (53 GPa vs 45 GPa) and Babbitt Grade 3 (Tin-Base) runs hotter in service (150°C vs 90°C continuous). On the shop floor, Babbitt Grade 3 (Tin-Base) machines more easily (excellent vs good).
Babbitt Grade 3 (Tin-Base)Choose it when the part sees heat, or when the part is machined in volume.
Type 2 Sheet PewterChoose it when the part is bent, formed or impact-loaded.
Babbitt Grade 3 (Tin-Base) vs Type 2 Sheet Pewter: 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.
