Magnets are made from different materials. Each material has special magnetic abilities and uses. The most common ones are ferrite, neodymium iron boron (NdFeB), aluminum nickel cobalt (AlNiCo), and samarium cobalt (SmCo). These materials help make magnets for many jobs.
Ferrite magnets are used a lot. By 2035, they may reach 37.34% of the market. People use them in cars, electronics, HVAC, and machines. They do not lose magnetism easily and cost less.
Neodymium iron boron magnets are becoming more popular. More people want them for electric cars, wind turbines, and new electronics. They are strong and work well.
AlNiCo and SmCo magnets are important too. They are used in special tools and places with high heat.
TAIXIONG makes many kinds of magnets from these materials. Their magnets help industries like cars, electronics, and factories.
The material of a magnet changes how strong it is, how long it lasts, and how well it works over time. Some magnets, like neodymium, are very strong. Others, like ferrite, do not rust and work in tough places.
| Property | Alnico Magnets | Neodymium Magnets |
|---|---|---|
| Max Energy Product | ~5.5 MGOe | Up to 52 MGOe |
| Coercivity | Low | Very high |
Permanent magnets can change as time passes. How well they work depends on what they are made of and where they are used. High heat can make rare earth magnets, like NdFeB, weaker. Wet air and chemicals can cause rust, which hurts magnet strength. Shaking and hitting can break magnets.
Sintered magnets and bonded magnets are different. Sintered magnets are strong and heavy. They are good for electric motors and MRI machines. Bonded magnets bend easily and do not rust. They are used in sensors and small motors.
TAIXIONG uses smart ways to make magnets that stay strong. Their magnets last longer and work well in hard places. The company makes sure their magnets are high quality for many jobs.
Tip: Picking the best magnet material makes magnets stronger and helps them last longer.
The size and shape of a magnet matter a lot. Bigger magnets have more area. This helps them pull harder. More mass also makes them stronger. Engineers pick the right size for each job. They want the magnet to fit and work well.
Shape changes how the magnetic field moves. A disc magnet has a strong field in one direction. It is good for careful tasks. A ring magnet makes a round field. It works well in spinning motors. Arc magnets fit into motors and help them run. Block magnets hold things on flat surfaces.
| Magnet Shape | Magnetic Field Distribution | Performance Impact |
|---|---|---|
| Disc Magnet | Concentrated axial field | High precision in applications |
| Ring Magnet | Donut-shaped flux | Ideal for rotational devices |
| Arc Magnet | Efficient motor geometries | Optimizes motor performance |
| Block Magnet | Broad holding force | Effective on flat surfaces |
The way the field spreads changes how strong or exact a magnet is.
The shape should match the device for best results.
Area and thickness change how strong the magnet is.
Special shapes can help with heat and save money.
Knowing these things helps people pick the right magnet. It also helps stop magnets from getting weak in hard jobs.
How thick the steel is also matters for magnets. When a magnet sticks to steel, thickness is important. Thick steel holds all the magnetic force. This keeps the pull strong. Thin steel cannot hold all the force. The steel gets full, and the pull drops. The magnet does not work as well.
If the steel is too thin, the pull goes down. If the steel is thick enough, the pull stays strong. People need to check steel thickness. This helps keep magnets strong and working well.
How well magnets are made is very important. Good quality means magnets work better and last longer. TAIXIONG uses smart ways to make magnets. Their factories use new materials and machines. Their team finds ways to make magnets stronger.

Temperature changes can make magnets weaker. High heat often lowers magnet strength, especially for neodymium magnets. If these magnets get too hot, they might lose their magnetism. Sometimes, they cannot get all their strength back. Ferrite magnets work well in heat but do not do well in cold. They lose power when it gets very cold, especially below 0°C. How much strength a magnet loses depends on its size, shape, and use.
There are three ways magnets lose strength:
Reversible loss: The magnet gets its strength back after cooling if it does not get too hot.
Irreversible loss: The magnet loses some power if it gets hotter than it should but not too hot. Cooling will not bring back all the strength.
Permanent loss: If the magnet gets way too hot, it cannot be fixed or re-magnetized.
The table shows the best temperature ranges for different magnets:
| Magnet Type | Optimal Temperature Range (°C) | Maximum Operating Temperature (°C) |
|---|---|---|
| Neodymium | -138 to 200 | 200 |
| Samarium Cobalt | 310 to 400 | 400 |
| Ferrite | Up to 250 | 250 |
| Alnico | Varies, generally lower than others | Varies, generally lower than others |
TAIXIONG has Samarium Cobalt magnets for hot places. These magnets stay strong up to 350°C and do not rust, so they do not need extra coatings.
Changing temperatures again and again can make magnets less stable. Magnets can lose power but get it back when cooled. Some magnets lose power that needs demagnetization to fix. Big temperature changes can cause permanent loss that cannot be fixed.
Keeping magnets at the right temperature helps them stay strong. Store magnets in dry places near room temperature. Keep the temperature between 15–30°C to stop stress. Humidity should be under 50% to stop rust, especially for neodymium magnets. Use wood or plastic to keep magnets apart so they do not hit each other.
TAIXIONG’s solutions help magnets work well in tough conditions. Their magnets keep their power and do not change much with temperature. This makes them good for many jobs.
Tip: Storing magnets the right way and keeping them at good temperatures helps them stay strong and last longer.
Magnets often work near machines and equipment. These things can make extra magnetic fields. Extra fields can change how strong magnets are. The effect depends on how close the equipment is. It also depends on how strong the field is. Far-end flux makes a steady field. Near-end flux from close equipment makes a changing field. Both types can change how magnets act. The table below shows how different fields affect magnets:
| Evidence Type | Description |
|---|---|
| Far-end Flux | Makes a steady field at the magnet’s spot, like the geomagnetic field. |
| Near-end Flux | Makes a changing field at the magnet, caused by nearby electrical equipment. |
| Coupling Mechanism | The up-and-down part of a far-end field can make a field gradient. The side-to-side part makes extra twists in measurements. |
| Shielding Effect | The yoke enclosure sends outside magnetic flux back to the magnet. This lowers the extra magnetic field in the air gap. |
TAIXIONG uses special covers and shields to protect magnets. These help magnets keep their strength and work well.
Magnets can get weaker if they are damaged. Dropping, hitting, or pressing magnets can cause cracks or chips. Sometimes magnets can break into pieces. The table below lists common damage types:
| Type of Damage | Description |
|---|---|
| Cracks | Magnets can crack from stress or sudden hits. This hurts their strength and how they work. |
| Chips | Small pieces can break off, especially in brittle magnets like ceramic or rare-earth magnets. |
| Breakage | Magnets can break apart. Fixing them needs careful lining up and bonding. |
Magnets also get weaker as they get older. Over time, magnets slowly lose power. This is called magnetic creep. Most magnets lose about 1% strength every ten years. Neodymium magnets lose power faster than others. Heat and tough places can make magnets age faster. Even so, most magnets stay strong for many years.
Tip: TAIXIONG puts rubber and plastic coatings on magnets. These coatings help stop chips and cracks. They also help magnets stay strong longer.
Humidity and chemicals can hurt how magnets work. Water in the air can cause rust and other changes. Neodymium magnets rust easily. If they stay in wet air, they can lose up to half their strength. High humidity makes rust happen faster. Rust hurts the magnet’s structure and power. Chemicals like acids or alkalis can also damage magnets. The table below shows how chemicals affect magnet coatings:
| Evidence Description | Impact on Magnet Coatings |
|---|---|
| Chemical reactivity of neodymium presents preservation challenges. | Shows why magnets need protection from chemical damage. |
| Exposure to acids and strong alkalis leads to accelerated degradation. | Proves that chemicals can hurt magnet performance. |
| Significant mass reduction observed in magnets stored in acidic and alkaline conditions. | Shows that chemicals can damage magnet coatings. |
| Magnets exposed to alkaline conditions showed a higher mass change compared to acidic conditions. | Means alkaline places are worse for magnets. |
| Corrosion tests showed rapid degradation in aggressive environments like acidic or basic solutions. | Shows magnet coatings are weak in harsh chemicals. |
| Neodymium magnets react with acids and strong alkalis, accelerating degradation. | Proves that chemical reactions make magnets weaker. |
| Cleaning agents can trigger harmful reactions with magnets. | Even common cleaners can hurt magnets. |
TAIXIONG uses many coatings to protect magnets. Nickel and zinc coatings help stop rust. Epoxy and Teflon coatings block water, salt, and chemicals. Rubber and plastic coatings add extra safety. These coatings help magnets stay strong in tough places.
