Solder & Low-Melting Alloy Babbitt Grade 1 (Tin-Base) vs WJ2
Solder & Low-Melting Alloy · grade comparison
Solder & Low-Melting Alloy Babbitt Grade 1 (Tin-Base) and WJ2 are both solder & low-melting alloy grades. WJ2 is the stronger of the two: yield strength 45 MPa (6.53 ksi) against 30 MPa (4.35 ksi) for Babbitt Grade 1 (Tin-Base), about 50% more; tensile strength follows at 85 MPa (12.3 ksi) vs 66 MPa (9.57 ksi). In exchange, Babbitt Grade 1 (Tin-Base) is the more ductile: elongation 8% versus 4% for WJ2, and WJ2 is harder (25 HB vs 17 HB).
Babbitt Grade 1 (Tin-Base)Choose it when the part is bent, formed or impact-loaded.
WJ2Choose it when strength drives the design.
Babbitt Grade 1 (Tin-Base) vs WJ2: 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.

Babbitt Grade 1 (Tin-Base) vs WJ2 — frequently asked
Is WJ2 stronger than Babbitt Grade 1 (Tin-Base)?
Yes. WJ2 has a typical yield strength of 45 MPa (6.53 ksi) against 30 MPa (4.35 ksi) for Babbitt Grade 1 (Tin-Base) — about 50% more. Tensile strength is 85 MPa (12.3 ksi) vs 66 MPa (9.57 ksi).
Which is cheaper, Babbitt Grade 1 (Tin-Base) or WJ2?
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 welds better, Babbitt Grade 1 (Tin-Base) or WJ2?
WJ2. Its weldability rates poor (25/100) against poor (20/100) for Babbitt Grade 1 (Tin-Base).
