Reputable suppliers should maintain robust traceability for raw materials, comply with global sourcing standards (such as REACH in Europe), and offer certificates of origin on request.

Alloy Melting:
Samarium and cobalt, often with minor alloying elements for specialized grades, are accurately weighed and melted in induction furnaces under an inert (argon) atmosphere to prevent contamination and oxidation. The resulting alloy is then rapidly cooled (casting), forming solid ingots ready for further processing.

---

2. Powder Preparation and Shaping

Pulverization:
The solid SmCo alloy ingots are crushed and pulverized under controlled atmosphere to prevent oxidation, resulting in a fine, homogenous powder—often less than 100 microns in particle size. The powder’s quality (particle size distribution, purity) is critical for final magnetic properties. State-of-the-art equipment ensures uniform particle size and minimizes contamination.

Magnetic Alignment and Compaction:
The powder is pressed into molds under high pressure—commonly isostatic or die pressing. During this stage, a strong magnetic field is applied to align the magnetic domains (the process is sometimes called “magnetic orientation pressing”), which directly influences the magnet’s performance. The geometry (block, disc, ring, arc, etc.) is determined by mold design, with customization available for B2B clients needing non-standard shapes.

---

3. Sintering and Machining

Sintering:
The compacted “green” bodies are sintered at high temperatures (typically 1100–1250°C) in controlled, inert or reducing atmospheres. This process causes powder particles to bond, densifying the part and locking in the magnetic orientation. Temperature and atmospheric control are vital, as deviations can negatively affect magnetic strength or mechanical robustness.

Precision Machining:
After sintering, the magnets are typically rough-shaped and require precision grinding or machining to achieve final dimensions and tight tolerances (often within ±0.05 mm).
