This metal has several minor uses in engineering. Of these the principal uses are:

(1) As sheet lead for lining tanks and basins because of its power to resist corrosion from air and from many dilute acids.

(2) As pipes in plumbing work due to its flexibility, ease of soldering, and qualities mentioned in item (1), although it cannot stand high heat or high pressure.

(3) As wire for gaging tightness of large engine bearings, and for electric fuses.

(4) As pigments for well-known paints in the form of "red lead" (oxide of lead), and of "white lead" (lead carbonate).

(5) Occasionally for alloying in small quantities with other metals to increase ductility and malleability.
