High-purity praseodymium metal is refined using vacuum induction melting (VIM) or electron beam melting (EBM) to remove impurities and ensure uniform chemical composition. Each batch is tested using GDMS, ICP-MS, and ONH analysis to verify purity and trace element control before processing.
Praseodymium ingots are hot-forged and rolled into solid rods with uniform grain structure and high density. For wire production, the rods are drawn through multiple precision dies to achieve the required diameter and dimensional accuracy.
Rods are heat-treated to relieve internal stress and stabilize the microstructure. During wire manufacturing, intermediate annealing restores ductility and ensures consistent strength and flexibility across the full length.
The surface of each rod and wire is polished and cleaned to achieve a bright, smooth, and oxide-free finish. Optional fine grinding or precision machining is applied when tighter dimensional tolerances are required.
All products undergo strict quality inspection for surface condition, dimensions, and mechanical integrity. Ultrasonic cleaning removes oil, particles, and residues, ensuring readiness for vacuum, optical, or alloying applications.
All finished products are vacuum-sealed in moisture-proof packaging and placed in shock-resistant cartons. Each shipment includes a Certificate of Analysis (COA) and complete documentation for traceability and quality assurance.
