Zirconium metal

Zirconium metal foil is a silver-gray metallic luster sheet material with the chemical formula Zr. It has physical and chemical properties such as high melting point and high boiling point, low density and high strength, good corrosion resistance, and excellent nuclear properties, and has been widely used in aerospace, nuclear industry, electronics, chemical industry, and medical fields.

Properties

Chemical formula: Zr

CAS No.: 7440-67-7

Appearance: Usually silver gray metallic luster flakes

High melting point and boiling point: Zirconium foil has a high melting point of about 1852℃ and a high boiling point of 4377℃. This enables it to maintain a stable physical state at high temperatures, and it is not easy to melt or evaporate, showing good thermal stability and can be used in some fields that require high temperature resistance of materials.

Low density and high strength: its density is about 6.49 g/cm³, relatively low density, light weight, but at the same time has a high strength, this combination of low density and high strength characteristics, so that it has a great advantage in aerospace, automotive and other fields, can be used for the manufacture of both the strength requirements of the weight reduction of parts, such as aircraft engines, heat insulation screen, automotive engine gaskets and so on.

Good corrosion resistance: zirconium has good corrosion resistance to most acids, alkalis, salts and other chemicals at room temperature, and can maintain good stability in some harsh chemical environments, and is not easy to corrode, thus prolonging its service life, and can be used for the manufacture of chemical equipment, marine engineering and other fields of corrosion-resistant parts, such as the lining of the chemical reactor, seawater desalination equipment parts and so on.

Excellent nuclear properties: zirconium has a small absorption cross-section for thermal neutrons, and has good nuclear properties, so it has important applications in the nuclear industry, and can be used as a structural material in nuclear reactors, fuel casing materials, etc., which plays a key role in ensuring the safe operation of nuclear reactors and improving the utilization rate of nuclear fuel.

Good flexibility and processability: Compared with zirconium metal in block or granular form, zirconium metal foil has better flexibility and processability, and can be easily bent, folded and cut into various shapes and sizes to meet the needs of different application scenarios, and it can be made into a variety of complex parts or structures through stamping, rolling, welding and other processing techniques.
