Zinc Ingot

Zinc is a moderately reactive bluish grey metal that tarnishes in moist air and burns in air with a bright bluish-green flame, giving off fumes of zinc oxide. It reacts with acids, alkalis and other non-metals. If not completely pure, zinc reacts with dilute acids to release hydrogen. The one common oxidation state of zinc is +2. From 100 °C to 210 °C (212 °F to 410 °F) zinc metal is malleable and can easily be beaten into various shapes. Above 210 °C (410 °F), the metal becomes brittle and will be pulverized by beating. Zinc is nonmagnetic.

An ingot is a material, usually metal, that is cast into a shape suitable for further processing.[1] It requires a second procedure of shaping, by means of cold/hot working to produce the final product. They involve relatively simple procedures. However, this only works for simple objects, such as shaping a bar ingot into a mallet tip. The advantages are low initial costs for producing the moulds. If cold worked, it can also improve hardness in the second procedure, an advantage for such things as the mallet tip. However, more input energy is required for the final object if hardness (by cold working) is not required.
