Zinc metal has been used for centuries. The presence of brass products dating back to 1000-1400 years ago is proof of its use in the past centuries. One of the products of zinc metal is zinc ingot. Zinc ingot is one of the best-selling and valuable products, which is produced through several steps, including zinc metal extraction, zinc concentrate, depot, sampling, zinc solution production, and finally zinc ingot.
Zinc bullion
Zinc ingots are made by crystallization of the crystal structure in the form of compressed hexagons or hcp and by freezing molten zinc in special molds. Zinc metal with atomic number 30 and chemical symbol Zn is one of the elements of the twelfth group of the periodic table. This brittle metal with a combination of silver and blue color is similar to the first metal of its group, the element magnesium. Zinc is found abundantly in the earth's crust and is the fourth most used metal in the world after iron, aluminum and copper, which has many industrial and biological applications. Zinc ingot is suitable for a wide range of applications, which is important. The most important is to improve corrosion resistance. In fact, many zinc ingots produced are used for the galvanizing process. In this way, it creates an anti-corrosion process to protect steel products and protects them from further corrosion and rust.
Zinc bullion features
This metal has found various uses in terms of functional properties such as reactivity with iron, corrosion resistance, electrochemical properties, low melting point, strength, alloyability, malleability, high tensile strength, etc. When this metal is alloyed with 4% aluminum, its yield strength and hardness increase greatly.
Strength and resistance
On a low strength metal with The elasticity is less than half that of mild carbon steel. Zinc ingots are commonly used in load bearing applications. However, cheap mechanical parts can be cast from zinc.
Hardness
Pure zinc has low hardness and is brittle in most cases, however Compared to other casting alloys, zinc alloys are exceptionally safe and more resistant to impact. Fahrenheit, it becomes malleable and malleable, but returns to its brittle state with increasing temperature.
Reactivity
Zinc has strong electrochemical properties, although in batteries Alkaline and works well during the galvanizing process. Ingots have strong anti-corrosion properties and are well combined with other metals.
