What is aluminum?

Aluminum is a bluish white (silver) metal. Although it is the most abundant metal in the earth’s crust (about 8%), it is not present in pure form and is obtained from mineral ore components. Components of structures made of aluminum are very important in the aviation industry and other stages of transportation. Also, in structures where weight, stability and strength are required, the presence of this element is very important.

The unique combination of aluminum and the excellent properties of aluminum alloys have made this metal one of the most important engineering and manufacturing materials. Light mass, high strength and high resistance to corrosion and rust make aluminum an excellent metal. Aluminum is recyclable and environmentally friendly.

Specifications of copper metal

Copper is a chemical element with the symbol cu ​​and has a very high flexibility and thermal conductivity. Copper is used as a building material and as a building material for various metal alloys such as sterling silver.

Copper has the chemical properties of transition metals, has oxidation states of +1 and +4, its compounds are colored, with atomic number 29 and atomic mass of 546/63.

Various physical properties including copper grade, amount of natural impurities or residues of additives formed at the boundary of solid solution grains or separate phases; Mechanical and thermal pretreatment of metal, which leads to conditions such as cast copper, hot tubular copper and hard copper, molding copper, spitting copper, are other features of copper metal.

This element is one of the few metals that can be used in nature as a metallic form. For this reason, it has been used by humans in different regions throughout history. Of course, this is not only because of its abundant resources in nature but also because of its excellent properties. The metal is currently used in electricity, electronics, energy, petrochemicals, transportation, machinery, metallurgy and other new industries and some advanced fields.

Zinc Metal Specification

On the shiny metal element is bluish white. At normal temperatures, it is brittle and crystalline, but at temperatures between 150-110 ° C, it has malleable properties. In terms of abundance, it is on the twenty-third element in the Earth’s crust. Zinc is a bluish-white metal that darkens due to humidity and produces a glossy green color during combustion. Zinc is the fourth most widely used metal in the world after iron, aluminum and copper….

Its main sources are sulfide, zinc boland or zincite sphalerite, calamine (zinc silicate) and smith sonite (zinc carbonate). Sulfide rock is roasted to be oxidized and heated with coal to 1200 ° C. It evaporates and condenses outside the reaction chamber and is molded into molds called splitters.

Zinc extraction method is obtained by burning and oxidizing zinc ore and the reaction of zinc oxide with coal or carbon by metal distillation. Zinc has 5 stable isotopes in nature and 16 unstable isotopes are known for zinc.

In the meantime, there is a consensus that the supply deficit will continue until new mines and smelters enter production. This deficit requires users to stockpile. On the other hand, as these stocks decline, the price of zinc is more likely to rise. if you want buy zinc from Iran please contact us.

Specifications of lead metal

Lead ( Plumbum or Lead ) is a soft and heavy metal with an atomic weight of 2/207. Lead has good corrosion resistance and is one of the oldest metals used by humans. Lead has a melting point of 327.5 ° C, a boiling point of 1740 ° C and a volume mass of 11.34 gr / cm3, and if you are familiar with the characteristics of copper metal, you will see that the thermal and electrical conductivity of lead metal is about 0.1 metal. It is copper. Dry lead is an alloy of lead with antimony-calcium with calcium-aluminum and tin. These alloys are usually called hard lead. Familiarity with the specifications and types of alloys of this metal makes it easier for you to buy lead metal .

Absorption of this metal from water and sediments and environmental accumulation in the food chain is a great danger for fish, birds and marine mammals.
