Hafnium Wire Production Process

• Melting and Casting: Hafnium sponge is melted and cast using an electron beam furnace or purified through iodization, followed by melting and casting to produce high-purity hafnium ingots.
• Forging and Rolling: The hafnium ingots are heated and then subjected to forging and rolling at high temperatures to form preliminary rods.
• Spin Forging: Depending on the bar’s diameter, the appropriate spinning machine and die are selected. Multiple spin forging processes are performed to achieve the desired dimensions.
• Dibujo: After intermediate annealing, the bar’s surface is evenly coated with graphite emulsion, which is then dried before being processed through a drawing die.
• Tratamiento térmico: The drawn hafnium wire undergoes heat treatment to relieve processing stresses and enhance its material properties.
• Finishing & Inspection: Steps such as cutting, polishing, cleaning, and strict quality inspection ensure that the product meets specifications.

Hafnium Wire Applications

• Plasma Cutting Electrodes: Hafnium wire is commonly used as the electrode material for plasma cutting machines.
• Industria nuclear: Hafnium wire is widely used in nuclear reactors’ control rods and shielding materials.
• Electronics Industry: Hafnium wire is a lead material in electronic devices, especially at high temperatures and frequencies.
• Aditivos de aleación: Hafnium wires are used as additives to improve the alloys’ mechanical properties and corrosion resistance.

Hafnium Wire Packaging

The Hafnium Wire is carefully placed in wooden cases or cartons with additional support from soft materials to prevent any shifting during transportation. This packaging method guarantees the integrity of the products throughout the delivery process.
