| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
fully recrystallized (soft) | Softest, most ductile condition for deep forming, dressing over irregular shapes and hand-burning repairs. | 8 | 20 | 50 | 5 HB | 7.9 % IACS |

as-extruded pipe, rod and sleeve | Pick for chemical-plant piping, traps and cable sheathing where creep and vibration fatigue resistance matter. | 12 | 24 | 38 | 6 HB | 7.8 % IACS |
cold rolled / drawn, work-hardened | Use where the extra ~20% strength of retained cold work is wanted — tellurium delays room-temperature recrystallization so the gain persists. | 16 | 28 | 25 | 7 HB | 7.7 % IACS |
What is Tellurium Lead-F?
Tellurium Lead-F is Tellurium Lead in the F temper — foundry/ingot condition for remelting, cast anodes and cast fittings; coarse grain gives the lowest strength. Tellurium Lead-F has a yield strength of 8 MPa (1.16 ksi) and a tensile strength of 19 MPa (2.76 ksi) — weaker than 93% of solder & low-melting alloy grades. Elongation at break is 30% and the elastic modulus is 14 GPa (2.03 Msi). Tellurium Lead-F has a density of 11.34 g/cm³ (0.41 lb/in³), heavier than 99% of solder & low-melting alloy grades. It melts at 327°C (621 °F).

Working with Tellurium Lead-F
Is Tellurium Lead easy to machine?
Cuts effortlessly with sharp, high-rake, well-polished tools and flood coolant, but smears and loads flutes — use light finishing cuts; capture all swarf and dust as hazardous waste.
Can Tellurium Lead be welded?
Joined by lead burning (oxy-hydrogen or oxy-acetylene) with matching tellurium-lead filler; keep heat input low, ventilate for lead fume, and expect weld-zone strength near annealed values.
Can Tellurium Lead be formed, bent or molded?
Bends, dresses and hammers cold to almost any shape; it work-hardens only slightly and tellurium slows self-annealing, so hold generous bend radii and support sheet against creep sag.
What surface finishes work on Tellurium Lead?
No anodizing or plating in practice — rely on the self-forming sulfate film, wire-brush before burning, and paint only over an etch/primer if a decorative or barrier coat is required.

Tellurium Lead-F — frequently asked
What is Tellurium Lead-F used for?
Tellurium Lead-F is typically used for sulfuric acid plant equipment, chemical tank linings and anodes for electrowinning. In short: best creep resistance in lead; fatigue-resistant sheet lead; upgrade over corroding lead.
What is the yield strength of Tellurium Lead-F?
Tellurium Lead-F has a typical yield strength of 8 MPa (1.16 ksi) and a tensile strength of 19 MPa (2.76 ksi) — weaker than 93% of solder & low-melting alloy grades. Strength varies by condition: see the 4 listed tempers.
Is Tellurium Lead-F easy to machine?
Reasonably — machinability is rated good (60/100, better than 76% of solder & low-melting alloy grades). Cuts effortlessly with sharp, high-rake, well-polished tools and flood coolant, but smears and loads flutes — use light finishing cuts; capture all swarf and dust as hazardous waste.
Can Tellurium Lead-F be welded?
Yes — weldability is rated very good (70/100). Joined by lead burning (oxy-hydrogen or oxy-acetylene) with matching tellurium-lead filler; keep heat input low, ventilate for lead fume, and expect weld-zone strength near annealed values.

What is the maximum service temperature of Tellurium Lead-F?
Tellurium Lead-F is rated for continuous use to about 110°C (230 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
