There are two types of magnets: Isotropic Magnet and Anisotropic Magnet.
Heterogeneous magnets are also divided into dry and wet type. Magnets need to be manufactured by moulds. Common specifications have ready-made moulds. If special shapes are needed, they should be notified in advance, because the moulding takes time.
Magnetite is a kind of hard sintered product, which is economical and durable. Residual flux density is based on size ratio and shape. It is necessary to know the dimension ratio, magnetic direction and the information of its individual use before designing.
Before purchasing ferrite magnets, customers must know the following things:
The specifications and types of ferrite magnets produced by our company are square, circular, circular, special-shaped, trapezoidal, irregular graphics and so on, which can be customized for production. All the sizes of magnets in our specifications are calculated in mm (mm).
1. Round size is usually expressed by D (because it belongs to special symbols for the convenience of most people to use D instead of at present), for example, D30X5MM denotes a magnet with a diameter of 30mm and a thickness of 5mm. This is the mathematical symbol "multiplier sign".
2. The size of a square is long X, wide X and high. Generally, F is used to represent the square. For example, F150x100x25MM means that the length of the square magnet is 150 mm, the width is 100 mm, and the thickness is 25 mm. Generally, by default, the last number indicates the direction of magnetization of the square magnet, such as the square of F150x100x2 5, and the direction of magnetization is 25MM, that is, the direction of magnetization in the high direction. NS has two largest facets, that is, 150 x 100 facets.
3. The dimension of the ring is the height of the outer diameter DX and the inner diameter DX. For example, the ring magnet of D60XD32X15 represents 60 mm in outer diameter, 32 mm in inner diameter and 15 mm in height. Height is also called thickness. At present, rings are also divided into straight holes and countersunk holes. The holes of straight holes are drilled vertically, while countersunk holes are divided into large holes and small holes. The depth of large holes and small holes are commonly known as screw holes.
If you need custom-made ferrite magnets, please contact our customer service to explain the size,
performance, quantity, tolerance requirements, magnetization direction, etc. you need to customize, we will customize production according to your requirements.
