Strontium and barium-based hexa ferrite powders with high coercivity, magnetic anisotropy and thermal stability — engineered for EMI shielding, microwave absorption, permanent magnets and rare-earth-free bonded magnet applications. Customizable particle size, saturation magnetization and coercivity to match your frequency band and application.
Azygos Global manufactures strontium and barium-based hexagonal ferrite (hexaferrite) powders, prized for their high magnetic anisotropy, strong coercivity and excellent chemical and thermal stability. Being rare-earth-free, hexa ferrites offer a cost-effective, supply-secure alternative to NdFeB and SmCo magnets for applications that don't need the highest energy product — including EMI shielding, microwave/radar absorption, permanent magnets, and bonded magnetic compounds. Particle size and magnetic parameters are tunable to target specific frequency ranges and end-use performance.

Hexa ferrite's crystal structure and magnetic behaviour make it a versatile, cost-efficient magnetic material for a wide range of industrial and defence-adjacent applications.
Saturation magnetization (Ms) and coercivity (Hc) requirements vary by application. Use this guide to identify the right hexa ferrite grade, or share your target frequency band / use-case with our technical team for a custom recommendation.
| Application | Saturation Magnetization (Ms) | Coercivity (Hc) | Why |
|---|---|---|---|
| Automotive (alternators, sensors, actuators, electric motors) | ~50–65 emu/g | ~800–1500 Oe | Needs good temperature stability (150–200°C) and moderate coercivity to resist demagnetization under varying load, without going as high as radar-absorbing grades. |
| Speaker & audio (loudspeakers, headphones, microphones) | ~60–80 emu/g | ~200–500 Oe (ferrite) / ~800–1000 Oe (NdFeB) | Audio magnets prioritize high flux density for efficient sound generation; excess coercivity makes tuning difficult. |
| General magnetic replacement (small motors, holding devices, educational kits) | ~40–60 emu/g | ~200–800 Oe | Cost-effective compositions with lower coercivity, easy to magnetize/demagnetize and mass produce. |

Azygos hexa ferrites are supplied to magnet manufacturers, EMI/EMC component makers, automotive suppliers and R&D labs across India and for export.
High coercivity and magnetic loss properties make hexa ferrite powders effective in EMI shielding composites and radar-absorbing materials across S, X and Ku bands.
Strontium and barium hexa ferrites are the industry-standard rare-earth-free choice for sintered and bonded permanent magnets in motors and holding devices.
Used in alternators, sensors, actuators and electric motor magnets where temperature stability and moderate coercivity are essential.
High flux density grades support efficient sound generation in loudspeakers, headphones and microphones.
Compatible with flexible rubber and bonded magnet compounds for magnetic stripes, damping sheets and sound-dampening sheeting.
Complements Azygos' EMI Shielding Powder Mix, MXene and Graphene Oxide product lines for advanced electromagnetic and stealth applications.
Hexa ferrite (hexagonal ferrite) powder is used in permanent magnets, EMI shielding composites, microwave/radar absorption materials, automotive sensors and actuators, loudspeakers, and rare-earth-free bonded magnet applications.
Both are M-type hexagonal ferrites with similar crystal structures and rare-earth-free composition. Strontium hexaferrite generally offers slightly higher coercivity and is more common in modern permanent magnets, while barium hexaferrite is valued for its stability and is widely used in bonded and flexible magnet compounds.
Azygos supplies hexa ferrite powder in 500 g and 5 kg lab/pilot-scale packs as well as 25 kg industrial packs, with larger bulk quantities available on enquiry for manufacturing-scale orders.
No. Hexa ferrites are rare-earth-free magnetic materials, making them a cost-effective and supply-secure alternative to NdFeB and SmCo magnets in applications that don't require the highest possible energy product.
Azygos hexa ferrite powders maintain magnetic and structural stability up to approximately 450°C, well suited for automotive and industrial environments involving elevated operating temperatures.
Yes. Azygos offers customizable saturation magnetization (≥40 to >80 emu/g) and coercivity (≥200 to 2000 Oe) so customers can select the grade best matched to their target application and frequency band.
Hexa ferrite's high magnetic anisotropy and tunable coercivity allow it to absorb and dissipate electromagnetic energy across S, X and Ku microwave bands, making it a key component in EMI shielding composites and radar-absorbing materials for electronics, telecommunications and defence-adjacent applications.
Azygos Global manufactures and supplies hexa ferrite and other magnetic and 2D nanomaterials from its facilities in Kanpur, Uttar Pradesh, and Bengaluru, Karnataka, India, with pan-India and export supply capability.
