Yes.
I was very rushed when making the earlier posts. Lead fails with a brittle fracture under tensile loading in 3 orthogonal directions.
Lead is so malleable because the re-crystalisation temperature is below normal ambient. When the crystalline structure is altered/damaged by work, it re-forms at normal temperatures and doesn't need heat treatment like other metals.
But its behaviour changes dramatically at low temps. Scott may not have perished in Antartica if he knew that. They used kerosene tins for carrying heating fuel. In those days the tins were a rectangular shape with soldered seams. At the low temps the solder failed, the ruptured tins lost their fuel, which also contaminated some stores.
