Buying magnets depends upon the use of magnets and each magnet has some specific characteristics and their use is determined according to the characteristics of the magnet. There are the basic two categories of magnet including offered by this magnets company:
- Neodymium magnets
- Ferrite magnets
The manufacturer in the circumstances and situations like follows recommends ferrite magnets:
- Rigid resources
- High Temperature
- Outside use
- Little aesthetics vital
Neodymium magnet is referred to be used in the below mentioned situations
- Especially high bonding agent force needed
- Limited gap
- Need of slight burden
- Nice coating
The cost of Ferrite materials is just a fraction of the NdFeb Material. The bonding force of the neodymium magnet is 10 times more than of the ferrite magnet. If the bonding force per kg is calculated, so the calculations will show that the according to the bonding force ferrite magnets are about 3 times less expensive than the neodymium magnets. This price analysis proves to be true in case of ring or block magnets and also for custom magnets bulk.
We can only take the cost advantage on purchasing magnets only when the size and weight of the magnets doesn’t matter. This is so because the weight of ferrite magnets is so much more than that of neodymium magnets but they both have some bonding forces.
Stability of price
Neodymium magnets are more subject to price fluctuations because they are manufactured from rare earth metals, while the ferrite magnets have nothing to do with price stability.
Resistance from temperature
Neodymium magnets are not temperature resistant, they are more often to lose their magnetization at 80 degree temperature while the Ferrite magnets are designed to be used in the temperate more than 250 degree which is too high for the neodymium magnets to survive. Neodymium magnets can only survive less than 40 degree of temperature.
Neodymium magnets are restricted to be used for indoor purposes, while the Ferrite magnets are dust and rust resistant and they could be used for the outdoor purposes.
Neodymium is so easy to break and they could be cracked easily. Due to this fragility, neodymium magnet can also cause injuries to the users. Ferrite is tough to break, if you want to break it you need to put heavy strain on it.
Losing bonding force
Both the magnets don’t lose their bonding force by themselves. Different external factors are there by which the magnets are demagnetized. These external factors may include heat, natural factors and strain.
Neodymium magnets normally have the tolerance of +/- 0,1 mm. But the tolerance is complicated in case of the ferrite magnets.
The ferrite magnets have very weak magnetic field and thus this can be protected quite with no trouble. Neodymium magnets need protection and more effort to send these magnets. These magnets if transported, should be send with 22 mm distance from each other otherwise, there would be a chance of demagnetization of these magnets.
