FAQ
1. What are the main application scenarios of Alnico 2 magnets?
Due to its high remanence (Br) and good temperature stability, Alnico 2 magnets are often used in precision instruments and sensors, such as electric meters, water meters, car dashboards, motor control systems, etc.13. In addition, they are also used in musical instruments (such as guitar pickups) and industrial equipment (such as magnetic chucks).
2. What parameters do you need to provide for custom Alnico 2 magnets?
The following parameters need to be clarified:
Dimensions and tolerances: such as diameter, length, surface finish, etc., choose casting or sintering process according to needs (casting is suitable for complex shapes, sintering has higher precision).
Magnetic performance requirements: such as remanence (Br), coercive force (Hcj), etc. The typical performance of Alnico 2 is (BH)max about 1.25 MGOe3.
Usage environment: operating temperature range (Alnico can withstand temperatures up to 450-550°C) and whether an anti-corrosion coating is required.
3. What is the difference between Alnico 2 and other Alnico models (such as Alnico 5)?
Magnetic properties: Alnico 2 has lower remanence but better temperature stability, which is suitable for precision measurement; Alnico 5 has a higher magnetic energy product and is suitable for high-intensity scenarios such as motors.
Process cost: Alnico 2 is mostly isotropic (casting process), while Alnico 5 often achieves anisotropy through magnetic field cooling, and the process complexity is higher.
4. What is the minimum order quantity and delivery cycle for customized Alnico 2 magnets?
The minimum order quantity is usually 10 pieces, depending on the supplier and process complexity26.
The delivery cycle is generally 8-14 days (standard products), and complex customization may be extended to 3-4 weeks. The mold development or heat treatment process needs to be communicated in advance.
5. What are the cost factors affecting customized Alnico 2 magnets?
Materials and processes: Casting processes are less expensive but have limited precision; sintering processes are suitable for small-size, high-precision requirements and have higher unit prices.
Batch and shape: Special-shaped structures (such as U-shaped and arc-shaped) require special molds, which increase costs; discounts are available for bulk purchases.
Surface treatment: Additional protective measures such as nickel plating and epoxy coating will increase costs.
