The advantages of AlNiCo cow magnet over other types of cow magnets are mainly reflected in the following aspects:
Good temperature stability
- Wide range of application:
AlNiCo magnets can work normally at high temperatures above 500℃, its Curie temperature can reach 860℃, and the maximum working temperature is about 550℃, while the upper limit of the working temperature of general magnets is lower, such as ordinary sintered ferrite magnets, which may demagnetize in high temperature environments, affecting the use effect.
- Small performance change:
The reversible temperature coefficient of the residual magnetism of AlNiCo magnets is better than – 0.02%/℃, which means that when the temperature changes, its magnetic properties change very little, and it can maintain a relatively stable magnetic force at the body temperature of the cow and various ambient temperatures, and continuously and effectively adsorb iron foreign bodies in the cow’s stomach.
Strong corrosion resistance
- Composition advantage:
Due to its relatively low iron content, it is not as easy to rust and corrode as some other magnetic materials. Therefore, in the acidic environment of the cow’s stomach, AlNiCo cow stomach magnets can better maintain their performance and structural integrity, and have a longer service life.
Reliable magnetic performance
- High remanence:
AlNiCo magnets have high remanence, can generate strong magnetic force, and effectively adsorb Iron foreign bodies in the cow’s stomach, to prevent foreign bodies from causing damage to the cow’s stomach.
Good mechanical properties
- High hardness:
Al-Ni-Co alloy itself is relatively hard, and the magnetic steel made has a high hardness. Under the mechanical action of the peristalsis and friction of the cow’s stomach, it is not easy to deform or damage, and can maintain a good shape and performance, and reliably play the role of adsorbing iron foreign bodies.
- Strong wear resistance:
In the process of long-term contact and friction with food and foreign bodies in the cow’s stomach, the surface is not easy to wear, thereby ensuring the effective adsorption area and magnetic strength of the magnetic steel.
Product shapes are diverse
- Manufacturing process support:
Al-Ni-Co magnets can be made into products of various shapes and sizes through casting or sintering processes, such as rods, strips, horseshoes, etc., which can better adapt to different cattle breeds, ages, body shapes, and different usage needs and delivery methods, while some other cattle stomach magnets may be relatively limited in the choice of shape and size.
Compared with other types of magnets for cow, the advantages of AlNiCo magnets are specifically reflected in:
- Compared with Ferrite magnets: AlNiCo magnets have higher remanence and greater magnetic field strength, and can more effectively attract metal foreign matter.
- Compared with NdFeB magnets: AlNiCo magnets have better high temperature resistance and less magnetic property attenuation in high temperature environments.
- Compared with SmCo magnets: AlNiCo magnets have relatively low cost.
Notice:
There are many NdFeB Cow magnets on the market that are covered with stainless steel shell instead of AlNiCo. The price is half that of AlNiCo, but this has great potential risks. AlNiCo is an integrated magnet, while the NdFeB one is not integrated, which is completed by welding and polishing. The surface is not smooth, which may be easy to scratch the cow’s stomach or fall off. Welding solder has a bad effect on the cow’s stomach. Moreover, the NdFeB used inside the shell are some NdFeB waste or even mixed with iron sheets, the magnetism cannot be guaranteed. Just because there is a shell on the outside, customers won’t know what is inside.
This has been a scam for more than 10 years, so many customers think that our AlNiCo magnets are expensive. Our magnets are made of pure AlNiCo magnets without adding any other ingredients, so the quality can be rest assured. Please contact info@hsmagnet.com for more details.
