Key Features and Benefits
1. Exceptional Soft-Magnetic Behavior
The B-CC structure provides low coercivity, high permeability, and stable magnetic response-ideal for engineers building transformers, magnetic yokes, sensors, and electromagnetic devices.
2. Ultra-Low Impurity Levels
The billet is produced with minimized C, S, P, and N contents. Low impurity levels significantly enhance ductility, minimize brittleness, and improve overall forming behavior.
3. Consistent Grain Structure
Thanks to controlled solidification and homogenization, the billet displays a remarkably uniform grain orientation. For customers who need predictable machining and forming, this stability reduces scrap rates and rework time.
4. Reliable Machinability
Users often report smoother cutting, cleaner chip formation, and lower tool wear. If your plant frequently machines high-precision magnetic components, this billet will help maintain process efficiency.
5. Stable During Heat Treatment
MELTBASE B-CC Billets respond well to annealing, stress relief, and magnetic treatment cycles without unexpected deformation or surface issues.
Typical Chemical Composition
Below is a reference table. Custom purity levels can be tailored based on customer needs:
| Element | Typical Content (%) | Remarks |
|---|---|---|
| Fe | ≥ 99.9 | High base purity |
| C | ≤ 0.005 | Essential for magnetic performance |
| S | ≤ 0.005 | Reduced brittleness |
| P | ≤ 0.010 | Controls grain boundaries |
| Si | ≤ 0.010 | Maintains softness |
| Mn | ≤ 0.010 | Minimizes inclusion formation |
| N | ≤ 0.003 | Reduces aging effects |
Mechanical & Magnetic Properties
While the exact values depend on the grade and heat-treatment specification, the following table provides common reference data:

| Tensile Strength | 250–300 MPa | Stable under cold forming |
| Elongation | 30–40% | Excellent ductility |
| Magnetic Permeability | High | Suitable for soft-magnetic parts |
| Coercivity | Low | Improves energy efficiency |
Applications
The MELTBASE B-CC Billet is widely used in industries that require reliable soft-magnetic materials or high-purity iron bases. Some common applications include:
Magnetic cores for transformers and reactors
Electromagnetic components
High-precision forging blanks
Industrial tools and small mechanical parts
Annealed components for electric machinery
Sensor housings and precision magnetic rings
Many manufacturers in the electronics, automotive, and energy sectors choose this billet because of its predictable magnetic performance and excellent processing adaptability.
Manufacturing Process Overview
To maintain stable quality, every MELTBASE B-CC Billet follows a complete traceable production cycle:
Raw Material Screening
Only high-purity base iron is selected. Trace impurities are monitored before melting.
Controlled Melting (Vacuum or Induction)
The melt is refined under controlled atmospheres to minimize gas content and inclusions.
In-Mold Solidification
Optimized cooling ensures an even B-CC crystal structure.
Homogenization Treatment
Removes internal segregation and refines grain distribution.
Surface Conditioning
Smooth surface preparation reduces defects in downstream machining.
Final Inspection
Ultrasonic testing, composition analysis, and dimensional checks ensure each billet meets MELTBASE quality standards.
Why Manufacturers Choose MELTBASE B-CC Billets
Predictable magnetic performance
Fewer inclusions, fewer production failures
Better machining life and tooling efficiency
Guaranteed purity consistency batch-to-batch
Stability during heat-treatment cycles
Excellent surface quality
If your production line deals with strict magnetic tolerance or precision forming, switching to MELTBASE B-CC Billet often results in reduced costs and higher reliability over time.
Packaging & Delivery
Billets are packaged with rust-preventive coating and protected with heavy-duty steel straps or wooden crates. Export packaging meets long-distance shipment requirements.
