Demand and design: Determine the magnetic field strength, polarity, size, length, width, height, opening angle, radius of curvature, etc. of the AlNiCo horseshoe magnet according to the application scenario.
Alloy smelting and casting: Heat the AlNiCo alloy to 1300-1400°C, accurately control the temperature after melting, and add flux to remove impurities. Pour the molten alloy into the horseshoe mold and cool it to form.
Annealing and magnetization heat treatment: Anneal at 800-1000°C to eliminate internal stress and improve magnetic properties. Heat to 500-600°C, apply a strong magnetic field for magnetization, and increase the magnetic field strength.
Cutting shaping and surface protection: Fine-process the magnet to the predetermined size to ensure accuracy and surface flatness. To prevent oxidation corrosion, choose electroplating or painting.
Magnetization and quality inspection: Use strong magnetization equipment to magnetize, check the magnetic field strength, polarity and surface quality to ensure that the product meets the design requirements.
Measuring instruments: They can generate stable magnetic fields in devices such as ammeters and voltmeters, enabling precise electrical measurements through interaction with the moving coil.
Analytical instruments: They are used in magnetic separation technology to separate biological or chemical samples, helping processes such as separation of cells or proteins in biochemistry.
Sensors: They are used in magnetic sensors, such as Hall effect sensors, for proximity, speed, and position sensing in devices such as smartphones, robots, and hard drives.
Data storage research: Due to its high coercivity and remanence, it is used in research to improve data storage density and stability.

1. What are the advantages of this U-shaped AlNiCo magnet compared with other magnets?
This magnet has unique advantages over other materials. First, it has a high remanence and can maintain strong magnetism, and can work stably in some equipment that requires a stable magnetic field. Secondly, its Curie temperature is as high as 800°C, and it can still maintain good magnetic properties in a high temperature environment, unlike many other magnetic materials whose magnetism is greatly weakened or even disappears at high temperatures. Moreover, its intrinsic coercivity is 1360 KA/m, and its anti-demagnetization ability is good. It can maintain its own magnetic stability in a complex magnetic field environment, and is suitable for instruments and other fields that require high magnetic field stability.
2. If we purchase in large quantities, will there be a discount in terms of price?
Regarding the price discount for large-scale purchases, we make a comprehensive consideration based on the purchase volume. Generally, we will give a corresponding discount when the purchase volume reaches a certain scale. You can tell us the specific purchase quantity, and we will calculate the discounted price for you in detail, and strive to provide you with a more cost-effective purchase plan.
3. How long is the delivery time of the product?
The delivery time mainly depends on your order quantity and the current production schedule. If it is a regular order volume and the production schedule is relatively loose, it can be delivered in 1-2 weeks. If the order volume is large or the current production task is full, it may take 2-4 weeks. We will communicate with you the specific delivery time as soon as you place the order, and make every effort to coordinate production resources to ensure that it is shipped to you as soon as possible.
4. How to avoid demagnetization during use of this magnet?
To avoid demagnetization, first of all, pay attention to the working temperature not exceeding the specified 500°C. Excessive temperature will weaken the magnetism. Secondly, try to minimize the effect of strong external magnetic fields on it, such as avoiding long-term close contact with other strong magnetic objects. In addition, during transportation and installation, avoid severe impact and vibration, because mechanical stress may also cause demagnetization.
