Alnico 8 Features
High coercivity: Alnico 8 has a high coercivity, usually around 1300-1500Oe, which means that it can resist the interference of external magnetic fields, maintain its own magnetic stability, is not easily demagnetized, and can maintain good magnetic properties in complex magnetic field environments.
Good temperature stability: It can maintain good magnetic properties in a high temperature environment, with a maximum operating temperature of 550℃, a low temperature coefficient, and a small change in magnetic properties due to temperature changes. It is suitable for occasions with high requirements for temperature stability.
Mechanical properties: It is hard and brittle, similar to other Alnico alloys. During the processing process, cutting or grinding and other processes are required to achieve the required size and precision.
Automobile field: commonly used in automobile sensors, motors and other components, vehicle speed sensors, crankshaft position sensors, etc., using its stable magnetism to accurately measure and transmit signals to ensure the normal operation of the car.
Instruments and meters: In various measuring instruments and meters, such as compasses, electronic balances, flux meters, etc., Alnico 8 can provide a stable magnetic field to ensure the measurement accuracy and stability of instruments and meters.
Motor field: can be used for small DC motors, stepper motors, etc., to provide a stable magnetic field for the motor, so that the motor can run efficiently and stably.
FAQ
1. Compared with other magnetic materials (such as NdFeB), what are the cost and performance advantages of this magnet?
Compared with NdFeB, this magnet has excellent magnetic stability in high temperature environment and does not require additional high temperature protection measures. In addition, its raw material price fluctuates less, and the long-term procurement cost is more controllable. If the application scenario is sensitive to temperature, this magnet can reduce the risk of equipment failure caused by high temperature demagnetization, and the overall cost is lower.
2. Can the coercivity and remanence of this magnet meet our needs for long-term stability of the sensor?
The coercivity of this magnet is 1300-1500Oe, and the remanence is 7900-8500G, which can effectively resist external magnetic field interference. We provide magnetic test reports issued by third-party organizations, and our products have passed ISO 9001 quality certification. In actual applications, in the field of automotive sensors, there has been no obvious demagnetization for more than 5 years, which can fully guarantee the long-term stable operation of the equipment.
3. How does your company's magnet packaging and transportation method ensure that the product is not damaged during transportation?
It adopts three-layer protective packaging of pearl cotton + anti-static plastic bag + carton, and adds customized foam lining for special-shaped parts or precision products. The default transportation uses a professional logistics company, which supports air, sea and land transportation, and provides full-process cargo insurance services to ensure zero damage to the product from factory to delivery. If there is transportation loss, we promise to respond and reissue within 24 hours.
4. Will the price of the magnet rise sharply due to raw material fluctuations in the future? Does your company provide a price guarantee mechanism?
We sign a long-term cooperation agreement with core raw material suppliers to lock in the purchase price within a certain period. At the same time, we reduce costs by optimizing the production process. For annual procurement contracts, price floating clauses can be negotiated. If the market price fluctuates by more than ±10%, the two parties will renegotiate the price to ensure that your procurement costs are controllable.
