Working with Tellurium Lead Cold Worked

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 Cold Worked — frequently asked

What is Tellurium Lead Cold Worked used for?

Tellurium Lead Cold Worked 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 Cold Worked?

Tellurium Lead Cold Worked has a typical yield strength of 16 MPa (2.32 ksi) and a tensile strength of 28 MPa (4.06 ksi) — weaker than 80% of solder & low-melting alloy grades. Strength varies by condition: see the 4 listed tempers.

Is Tellurium Lead Cold Worked easy to machine?

Reasonably — machinability is rated good (62/100, better than 78% 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 Cold Worked 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 surface finishes work on Tellurium Lead Cold Worked?

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.

Can Tellurium Lead Cold Worked 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 is the maximum service temperature of Tellurium Lead Cold Worked?

Tellurium Lead Cold Worked is rated for continuous use to about 90°C (194 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
