High Performance disc Alnico Magnet  is mainly composed of aluminum, nickel, cobalt, copper and iron, has good corrosion resistance, and the maximum working temperature can reach 550 degrees Celsius.

The metal of High Performance disc Alnico Magnets is very ductile and can be processed into a variety of shapes and sizes.

Performance disc Alnico Magnets are widely used in instrumentation, aerospace, military, automotive industry and security systems.

Performance disc Alnico Magnets are based mainly on iron (Fe), aluminum (Al), nickel (Ni) and cobalt (Co). The magnets are fragile
and not ductile. Therefore, after the raw metal is melted at high temperature and turned into an alloy, it is cast into a casting mold. These magnets are therefore also known as cast magnets.

Performance disc Alnico Magnets achieve high Br values and high temperature stability, readily cause low-temperature demagnetization and thermal demagnetization, achieve high mechanical strength, and offer other advantages. However, these magnets have low magnetic coercive force and readily undergo demagnetization due to an external magnetic field, are unsuited for thin products, and placed
under other constraints. In the design process, it is therefore important to select a method of magnetization
that allows for sufficient shape and magnetic characteristics, and a method of assembly in which consideration is given to demagnetization.

Disc Alnico magnet is own for their excellent temperature stability, high magnetic strength, and durability. Here are the typical technical parameters for high-performance disc Alnico magnets:

• 1. Material Composition: – Aluminum (Al): 8-12% – Nickel (Ni): 15-26% – Cobalt (Co): 5-24% – Copper (Cu): 6% – Iron (Fe): Balance – Small amounts of Titanium (Ti) or Niobium (Nb)may be included to enhance specific properties.
• 2. Magnetic Properties: – Residual Induction (Br): 6,500 – 13,500 Gauss (0.65 – 1.35 Tesla) – Coercive Force (Hc): 640 – 1,800 Oersteds (51 – 143 kA/m) – Intrinsic Coercive Force (Hci): 600 – 1,200 Oersteds (48 – 95 kA/m) – Energy Product (BHmax): 5.5 – 9.5 MGOe (43.75 – 75.6 kJ/m³)
• 3. Physical Properties: – Density: 7.3 g/cm³ – Electrical Resistivity: 47 μΩ·cm – Thermal Conductivity:46 W/(m·K) – Melting Point: ~1,350°C
• 4. Temperature Stability: – **Maximum Operating Temperature**: Up to 540°C (1,004°F) – Curie Temperature: 850 – 900°C (1,562 – 1,652°F) – Alnico magnets maintain about 90% of their room-temperature magnetization at temperatures up to 500°C (932°F).
• 5. Mechanical Properties: – **Hardness**: Rockwell C 50-55 – Tensile Strength: 450 – 700 MPa – Compressive Strength: 700 – 1,000 MPa
• 6. Tolerance: – Typical machining tolerance for Alnico magnets is ±0.1mm, but this can vary based on specific requirements and manufacturing capabilities.
