What is Corroding Lead Cast?
Corroding Lead Cast is Corroding Lead in the Cast grade — use where only mass/shielding matters and dimensional precision is loose; casting is trivial at 350–420 °C. Corroding Lead Cast has a yield strength of 6 MPa (0.798 ksi) and a tensile strength of 12 MPa (1.74 ksi) — weaker than 98% of solder & low-melting alloy grades. Elongation at break is 25% and the elastic modulus is 14 GPa (2.03 Msi). Corroding Lead Cast 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 Corroding Lead Cast
Is Corroding Lead easy to machine?
Cuts with almost no force but smears and loads tools — use sharp high-rake HSS, wide chip clearance, no coolant mist, and capture swarf/dust under local exhaust for toxicity control.
Can Corroding Lead be welded?
Joined by lead burning (oxy-hydrogen or oxy-acetylene torch with pure-lead filler strip) or by soldering; keep fume extraction, no flux needed for burning.
Can Corroding Lead be formed, bent or molded?
Extremely formable cold — rolling, bossing, hammering and extrusion all work, and lead recrystallizes at room temperature so it never work-hardens; cast easily at 350–420 °C.
What surface finishes work on Corroding Lead?
No anodizing or plating in practice; surfaces self-patinate to grey PbO/PbCO₃, can be painted with alkali-resistant primers or left bare in sulfuric-acid service.

Corroding Lead Cast — frequently asked
What is Corroding Lead Cast used for?
Corroding Lead Cast is typically used for battery oxide feedstock, lead pigment production and chemical lead compounds. In short: highest-purity lead grade; chemical feedstock quality; softest of the family.
What is the yield strength of Corroding Lead Cast?
Corroding Lead Cast has a typical yield strength of 6 MPa (0.798 ksi) and a tensile strength of 12 MPa (1.74 ksi) — weaker than 98% of solder & low-melting alloy grades. Strength varies by condition: see the 2 listed tempers.
Is Corroding Lead Cast easy to machine?
Reasonably — machinability is rated good (55/100, better than 74% of solder & low-melting alloy grades). Cuts with almost no force but smears and loads tools — use sharp high-rake HSS, wide chip clearance, no coolant mist, and capture swarf/dust under local exhaust for toxicity control.
Can Corroding Lead Cast be welded?
Yes — weldability is rated good (58/100). Joined by lead burning (oxy-hydrogen or oxy-acetylene torch with pure-lead filler strip) or by soldering; keep fume extraction, no flux needed for burning.
What surface finishes work on Corroding Lead Cast?
No anodizing or plating in practice; surfaces self-patinate to grey PbO/PbCO₃, can be painted with alkali-resistant primers or left bare in sulfuric-acid service.
Can Corroding Lead Cast be formed, bent or molded?
Extremely formable cold — rolling, bossing, hammering and extrusion all work, and lead recrystallizes at room temperature so it never work-hardens; cast easily at 350–420 °C.
What is the maximum service temperature of Corroding Lead Cast?
Corroding Lead Cast 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.
