Solder & Low-Melting Alloy Type 1 Casting Pewter vs Type 2 Sheet Pewter
Solder & Low-Melting Alloy · grade comparison
Solder & Low-Melting Alloy Type 1 Casting Pewter and Type 2 Sheet Pewter are both solder & low-melting alloy grades. Type 2 Sheet Pewter is the stronger of the two: yield strength 43 MPa (6.24 ksi) against 34 MPa (4.93 ksi) for Type 1 Casting Pewter, about 26% more; tensile strength follows at 68 MPa (9.86 ksi) vs 58 MPa (8.41 ksi). In exchange, Type 1 Casting Pewter is the more ductile: elongation 30% versus 25% for Type 2 Sheet Pewter, and Type 2 Sheet Pewter is harder (25 HB vs 23 HB). On the shop floor, Type 1 Casting Pewter machines more easily (very good vs good).
Type 1 Casting PewterChoose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
Type 2 Sheet PewterChoose it when strength drives the design.
Type 1 Casting Pewter vs Type 2 Sheet Pewter: 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.

Type 1 Casting Pewter vs Type 2 Sheet Pewter — frequently asked
Is Type 2 Sheet Pewter stronger than Type 1 Casting Pewter?
Yes. Type 2 Sheet Pewter has a typical yield strength of 43 MPa (6.24 ksi) against 34 MPa (4.93 ksi) for Type 1 Casting Pewter — about 26% more. Tensile strength is 68 MPa (9.86 ksi) vs 58 MPa (8.41 ksi).
Which is cheaper, Type 1 Casting Pewter or Type 2 Sheet Pewter?
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, Type 1 Casting Pewter or Type 2 Sheet Pewter?
Type 1 Casting Pewter. Its machinability rates very good (72/100) against good (60/100) for Type 2 Sheet Pewter.
