Solder & Low-Melting Alloy B23 Grade 13 vs Pb-Ca-Sn Battery Grid Alloy
Solder & Low-Melting Alloy · grade comparison
Solder & Low-Melting Alloy B23 Grade 13 and Pb-Ca-Sn Battery Grid Alloy are both solder & low-melting alloy grades. Pb-Ca-Sn Battery Grid Alloy is the stronger of the two: yield strength 35 MPa (5.08 ksi) against 30 MPa (4.35 ksi) for B23 Grade 13, about 17% more. Pb-Ca-Sn Battery Grid Alloy is the more ductile: elongation 12% versus 6% for B23 Grade 13, and B23 Grade 13 is harder (22 HB vs 18 HB). B23 Grade 13 is lighter (10.24 g/cm³ vs 11.28 g/cm³ for Pb-Ca-Sn Battery Grid Alloy) and B23 Grade 13 is stiffer (29 GPa vs 16 GPa). On the shop floor, B23 Grade 13 machines more easily (very good vs fair), Pb-Ca-Sn Battery Grid Alloy welds better (good vs poor), and Pb-Ca-Sn Battery Grid Alloy sits in a lower cost tier (standard, $$) than B23 Grade 13 (high, $$$$).

B23 Grade 13 vs Pb-Ca-Sn Battery Grid Alloy: 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.
