| 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 fabricated | Foundry/ingot condition for remelting, cast anodes and cast fittings; coarse grain gives the lowest strength. | 8 | 19 | 30 | 5 HB | 7.7 % IACS |
ExtrudedThis page 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 |

Working with Tellurium Lead Extruded
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.

What is Tellurium Lead Extruded used for?
Tellurium Lead Extruded 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 Extruded?
Tellurium Lead Extruded has a typical yield strength of 12 MPa (1.74 ksi) and a tensile strength of 24 MPa (3.48 ksi) — weaker than 88% of solder & low-melting alloy grades. Strength varies by condition: see the 4 listed tempers.
Is Tellurium Lead Extruded 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 Extruded be welded?
Yes — weldability is rated very good (75/100). 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.

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 is the maximum service temperature of Tellurium Lead Extruded?
Tellurium Lead Extruded is rated for continuous use to about 120°C (248 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
