About This Product
In addition to standard and stock items, some custom -made shapes are possible, but please contact us as there are restrictions. It is a magnet that is difficult to obtain in Japan, but we will cooperate as much as possible.
Features
■ Relatively high BR with long metal magnets with long history
-Alnico magnets are the main components of aluminum, nickel, cobalt, and iron, and are metal magnets manufactured or sintered.
・ BR is high, and most of the materials exceed 10,000 (g).
■ resistant to temperature changes
-The temperature coefficient of BR is the smallest of -0.02%/° C, and is a magnet whose opposite temperature change is small.
・ The temperature coefficient of HCJ is almost zero to around 600 ° C, and it is a magnet that can be used high temperature.
■ External magnetic fields and mechanical impact are easy to reduce magnetism
・ Because the value of HCJ is small, care must be taken because it is easy to magnify in the external reverse magnetic field (inverted field).
・ HCJ tends to decrease due to mechanical impact, and it is necessary to pay attention to mechanical vibration and impact.
■ There is a limit to the shape
・ Because the value of HCJ is small, it is necessary to increase the height dimensions in the magnetization direction.
・ Depending on the shape, there are restrictions on molds and molds, but the dimension accuracy is highly finished by polishing.
■ Use
The stability of the temperature is outstanding, and there is a strong demand, mainly instruments. For example, this magnet is used in the settlement power meter in each family.
