On the Corrosion Proof, Mechanical Properties and Microstructures of Lead and Lead Alloys

Abstract

Some chemical,mechanical and microstructural experiments of lead and lead antimony alloys as the materials for the apparatus in the chemical industry, have been studied. (1) At temperature range of 50∼80°, the more antimony is contained in lead, the better H₂SO₄ resistivity is shown. (2) On account of containing Te and Cu, the flash point of lead-rich alloys rises, but contaning Bi, Zn, Sn and Sb it is lowered. (3) As the lamella β phase are made in grain structure, the tensile strength of the rolled lead is lower than the one casted having both the same content of Pb-Sb alloy. (4) The present authors have explained the relation between the microstructure and the flash point, on lead and lead rich alloys.
