What is the composition of lead ingots

The composition of lead ingots.

Lead ingot is divided into large ingot and small ingot. The ingot is a rectangular trapezoid with bunched grooves at the bottom and protruding ears at both ends. The large ingot is trapezoid, with T - shaped convex block at the bottom, and hanging slots on both sides.

Lead ingots are rectangular, with protruding ears at both ends, blue white metal, soft. The density is 11.34g/cm3 and the melting point is 327℃

1. The surface of lead ingot shall not contain slag, particulate oxygen, inclusions and foreign pollution.

2. Lead ingots shall not have cold compartments, and shall not have flying burrs larger than 10mm (trimming is allowed).

Test method: Arbitration analysis method for chemical composition of lead ingot shall be conducted according to the provisions of GB/T4103 "Chemical Analysis Method for Lead and Lead alloy".
