Solder & Low-Melting Alloy Babbitt Grade 2 (Tin-Base) vs ZSnSb8-4
Solder & Low-Melting Alloy · grade comparison
Solder & Low-Melting Alloy Babbitt Grade 2 (Tin-Base) and ZSnSb8-4 are both solder & low-melting alloy grades. ZSnSb8-4 is the stronger of the two: tensile strength 77 MPa (11.2 ksi) against 66 MPa (9.57 ksi) for Babbitt Grade 2 (Tin-Base), about 17% more. ZSnSb8-4 is the more ductile: elongation 5% versus 3% for Babbitt Grade 2 (Tin-Base).
ZSnSb8-4Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
Babbitt Grade 2 (Tin-Base) vs ZSnSb8-4: 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 2 (Tin-Base) vs ZSnSb8-4 — frequently asked
Is ZSnSb8-4 stronger than Babbitt Grade 2 (Tin-Base)?
Yes. ZSnSb8-4 has a typical tensile strength of 77 MPa (11.2 ksi) against 66 MPa (9.57 ksi) for Babbitt Grade 2 (Tin-Base) — about 17% more.
Which is cheaper, Babbitt Grade 2 (Tin-Base) or ZSnSb8-4?
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, Babbitt Grade 2 (Tin-Base) or ZSnSb8-4?
Babbitt Grade 2 (Tin-Base). Its machinability rates excellent (85/100) against very good (80/100) for ZSnSb8-4; for welding the order is Babbitt Grade 2 (Tin-Base) first (poor, 20/100) then ZSnSb8-4 (poor, 15/100).
