Chemical name: Zinc-ingot Performance: Silvery white and light blue gray metal, density 7.14g/cm3, melting point 419ºC, boiling point 907ºC. It can react with acid, alkali and salt resulting in zinc salt. It cannot be oxidized by dry air under normal temperature but its surface can be oxidized when it is exposed to moisture, and resulting in a dense gray-white film of basic zinc carbonate to protect its inner part. |
 |
Functions: It is mainly used in such fields as zincification,zinc alloy,chemical engineering, battery,etc.
Packing: trapezoid cuboid, size (406±15mm)×(205±10mm)×(50±10mm). 20kg-25kg/per piece, bound with zinc-coating cold-rolled steel strips, net weight 1000kg±50kg/per bundle.
Features: Our zinc ingots are produced through distillation so it has the features of low impurity, good tractility and strong activity, etc. Our company also produces high-purity zinc-ingot applied in non-mercury battery.The standards of our zinc-ingot products are as chart 3.
