Product Overview
Hafnium rod is a high-purity silver-gray transition metal with excellent high-temperature and corrosion resistance properties. With a density of 13.31 g/cm³, hafnium remains chemically stable at room temperature and forms a protective oxide layer in air. In powder form, hafnium is highly reactive and can self-ignite. The rod maintains its heat resistance and oxidation resistance at high temperatures, making it ideal for applications requiring exceptional heat and corrosion resistance.
Features
- High Density and Exceptional Heat Resistance:Perfect for high-temperature environments.
- Strong Corrosion and Oxidation Resistance:Suitable for harsh and corrosive conditions.
- Stable at High Temperatures:Easy to process and customize for various applications.
- Good Thermal Conductivity:Ideal for applications that require rapid heat absorption and dissipation.
Applications
- Nuclear Industry:Due to its large neutron absorption cross-section, hafnium is used in nuclear reactors as control rods and shielding devices.
- High-Temperature Materials:Widely used in aerospace applications, hafnium rods serve as high-temperature materials for rocket nozzles, injectors, and other critical components.
- Alloy Manufacturing:Hafnium is alloyed with other metals such as tungsten and molybdenum to improve strength and heat resistance, commonly used in high-performance alloy production.
- Electronic Materials:Hafnium rods are used in high-temperature electronic devices, such as high-temperature electrodes and electron tubes.
- Corrosion-Resistant Materials:Its excellent corrosion resistance makes hafnium ideal for use in high-temperature chemical environments, including applications in the petroleum and chemical industries.
- Heat Exchange and Radiation Control:Hafnium rods are used in heat exchangers and radiation shielding, where quick heat absorption and release are essential.
