Frequently Asked Questions—Hook AlNiCo Magnet
1. What is the maximum operating temperature for Hook AlNiCo Magnet?
Hook AlNiCo Magnet maintains stable magnetic performance in temperatures ranging from -40°C to 310°C. The Curie temperature ranges from 310 to 380 °C, making it suitable for high-temperature industrial applications where other magnet types may fail.
2. Can I customize the color of the nickel coating for Hook AlNiCo Magnet?
Yes, while the standard finish is red nickel coating, we offer custom color options for Hook AlNiCo Magnet, including black, blue, and natural nickel. Minimum order quantities may apply for custom color requests.
3. What mounting options are available for Hook AlNiCo Magnet?
The integrated central hole design allows for easy screw mounting. For specialized applications, we can customize notch positions and sizes to accommodate specific assembly requirements for your Hook AlNiCo Magnet.
4. How does Hook AlNiCo Magnet compare to neodymium magnets?
Hook AlNiCo Magnet offers superior temperature stability (up to 380°C vs. 80-200°C for neodymium) and better corrosion resistance, though with lower magnetic strength. It’s ideal for high-temperature environments where neodymium magnets would demagnetize.
5. What quality control measures are in place for Hook AlNiCo Magnet?
Each Hook AlNiCo Magnet undergoes dimensional inspection (with a tolerance of ±0.1mm), magnetic performance testing, and coating adhesion checks. We provide material certification and magnetic property reports upon request.
