PURITY REQUIREMENTS:

High purity is a key indicator, and the purity of hafnium wire is generally required to be 99.9% or above. High-purity hafnium wire can ensure good conductivity and stability during plasma cutting, reduce the impact of impurities on the cutting effect, make the cutting process smoother, and the cutting quality is higher.

DIMENSIONAL ACCURACY:

Diameter accuracy: The diameter of the hafnium wire needs to maintain a high consistency, and the diameter error should usually be controlled within a very small range. For example, for some common plasma cutting applications, the diameter of the hafnium wire may require an accuracy of ±0.05mm or even higher to ensure stable current transmission during the cutting process and ensure the stability and uniformity of the cutting arc.

Length accuracy: According to different plasma cutting equipment and process requirements, the length of the hafnium wire also needs to be precisely controlled. Too long or too short hafnium wire may affect the normal operation of the equipment and the cutting effect.

SURFACE QUALITY:

Finish: The surface of the hafnium wire should have a high finish, without obvious scratches, pits, burrs, and other defects. The smooth surface can reduce the energy loss of the current during transmission, reduce the local discharge caused by the uneven surface, and improve the cutting efficiency and quality.

Cleanliness: The surface should be kept clean and free of impurities such as oil, dust, and oxides. These impurities will affect the conductivity and welding performance of the hafnium wire, resulting in an unstable arc and poor cutting effect during plasma cutting.

MECHANICAL PROPERTIES:

Strength: The hafnium wire needs to have sufficient strength to withstand the mechanical and thermal stresses generated during plasma cutting. Hafnium wire with insufficient strength may break or deform during the cutting process, affecting normal cutting.

Toughness: Good toughness can make the hafnium wire not easy to break when subjected to external forces. Especially during installation and use, the hafnium wire needs to have a certain toughness to adapt to various complex working conditions.

WELDING PERFORMANCE:

In the process of making plasma-cutting electrodes, hafnium wire needs to be welded with other parts. Therefore, hafnium wire should have good welding performance and can be firmly welded with other metal materials. For example, in some non-vacuum brazing processes, hafnium wire needs to be welded with a copper matrix, which requires the hafnium wire to be fully combined with the solder during the welding process to form a firm weld to ensure the reliability and service life of the electrode.

FAQ
