This is a big ring sintered ferrite magnets with hole, also can be referred to as 180mm magnetic ring, the material is sintered ferrite, the specific size is 180mm outer diameter, 85mm inner hole, 20mm thickness. The tolerance is ±0.1mm.
Are there other size of inner hole 180mm sintered ferrite rings?
Of course, we are the manufacturer, and you can customize magnets according to your need about specifications, surface coating color, magnetic charging direction, working temperature, etc.
In terms of size, I need to explain that the tolerance of ferrite is ± 0.1mm.
Exist ferrite samples specification -180mm outer hole
The advantages of sintered ferrite:
Compare with sintered Ndfeb , the advantage of sintered ferrite including:
1.Low cost, low price. Raw materials cost very cheap.
2.Good temperature stability. It can be used at temperatures less than 200 degrees Celsius.
The way of 180mm outer diameter ring magnet:
It can be widely used in all kinds of automobile motors, home appliances, speakers, sensors, smart home, goods packaging, electronic hardware products, toys and water pumps and other places
