Solder & Low-Melting Alloy B560 Type III Cold Rolled vs B560 Type III Extruded
Solder & Low-Melting Alloy · B560 Type III temper comparison
B560 Type III Cold Rolled and B560 Type III Extruded are two conditions of the same solder & low-melting alloy grade, B560 Type III: Cold Rolled versus Extruded (extruded rod / tube / wire). The chemistry is identical, so every difference below comes from the condition. B560 Type III Cold Rolled is the stronger of the two: yield strength 34 MPa (4.93 ksi) against 26 MPa (3.77 ksi) for B560 Type III Extruded, about 31% more; tensile strength follows at 52 MPa (7.54 ksi) vs 45 MPa (6.53 ksi). In exchange, B560 Type III Extruded is the more ductile: elongation 38% versus 25% for B560 Type III Cold Rolled, and B560 Type III Cold Rolled is harder (21 HB vs 18 HB). B560 Type III Extruded runs hotter in service (100°C vs 75°C continuous).
B560 Type III Cold RolledChoose it when strength drives the design.
B560 Type III ExtrudedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
B560 Type III Cold Rolled vs B560 Type III Extruded: 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.
