Solder & Low-Melting Alloy Antimonial Lead 6% vs B23 Grade 14
Solder & Low-Melting Alloy · grade comparison
Solder & Low-Melting Alloy Antimonial Lead 6% and B23 Grade 14 are both solder & low-melting alloy grades. B23 Grade 14 is the stronger of the two: yield strength 30 MPa (4.35 ksi) against 25 MPa (3.63 ksi) for Antimonial Lead 6%, about 20% more; tensile strength follows at 65 MPa (9.43 ksi) vs 50 MPa (7.25 ksi). In exchange, Antimonial Lead 6% is the more ductile: elongation 24% versus 3% for B23 Grade 14, and B23 Grade 14 is harder (21 HB vs 13 HB). B23 Grade 14 is lighter (9.73 g/cm³ vs 10.88 g/cm³ for Antimonial Lead 6%) and B23 Grade 14 is stiffer (29 GPa vs 17 GPa). On the shop floor, B23 Grade 14 machines more easily (excellent vs very good), Antimonial Lead 6% welds better (good vs not recommended), and Antimonial Lead 6% sits in a lower cost tier (premium, $$$) than B23 Grade 14 (high, $$$$).
Antimonial Lead 6%Choose it when the part is bent, formed or impact-loaded, or when it will be welded.
B23 Grade 14Choose it when strength drives the design, or when weight is the constraint.
Antimonial Lead 6% vs B23 Grade 14: 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.
