Alnico industrial magnets are made from a combination of aluminum, cobalt, and nickel, with possible additions of copper, iron, and titanium. Compared to samarium-cobalt magnets, alnico magnets can endure even higher temperatures, up to 525 °C, making them highly heat-resistant. They are also more susceptible to demagnetization due to their ...

Generally, bigger magnets are stronger than smaller magnets made of the same material. Also, magnets with a simple shape like a disc or cylinder tend to be stronger than magnets with a more complicated shape. Where you'll use the magnet: Think about where you'll be using the magnet. Will it be hot or wet or in a place where things can corrode?
