Solder & Low-Melting Alloy Chemical Lead vs Corroding Lead
Solder & Low-Melting Alloy · grade comparison
Solder & Low-Melting Alloy Chemical Lead and Corroding Lead are both solder & low-melting alloy grades. Chemical Lead is the stronger of the two: tensile strength 17 MPa (2.47 ksi) against 13 MPa (1.89 ksi) for Corroding Lead, about 31% more. Chemical Lead is the more ductile: elongation 50% versus 35% for Corroding Lead. On the shop floor, Chemical Lead welds better (very good vs good).
Chemical LeadChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
Chemical Lead vs Corroding Lead: 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.

Chemical Lead vs Corroding Lead — frequently asked
Is Chemical Lead stronger than Corroding Lead?
Yes. Chemical Lead has a typical tensile strength of 17 MPa (2.47 ksi) against 13 MPa (1.89 ksi) for Corroding Lead — about 31% more.
Which is cheaper, Chemical Lead or Corroding Lead?
Both sit in the same relative cost tier ($$, standard); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which welds better, Chemical Lead or Corroding Lead?
Chemical Lead. Its weldability rates very good (75/100) against good (60/100) for Corroding Lead.
