Product Details

Custom Big Ring Ferrite Magnet

Products Introduction:

Ferrite magnets are BaFe12O19 and SrFe12O19 as raw materials.

Ferrite (ferrites) is a non-metallic magnetic materials. It is composed of iron oxide and one or more other metal oxides (such as : nickel oxide, zinc oxide, manganese oxide, magnesium oxide, barium oxide, strontium oxide and  etc.) preparation sintered

Ferrite have hard magnetic, soft magnet ,  rectangular magnetic, spin magnetic and piezomagnetic five. Formerly known as ferrite or ferrite magnetic material, its production process and looks like ceramic, which is also known as magnetic porcelain.

Ferrite is a composite oxide of iron and other one or more metal elements. It nature is a semiconductor, , usually as a magnetic media to use, the most important distinction between the ferrite magnetic material and a metal or alloy magnetic is  conductivity.

Ceramic or ferrite magnets are low cost and light weight, and are a relatively high energy member of the permanent magnet family. Iron oxide and strontium carbonate, the two materials in ceramic magnets, are easily attainable and available at lower costs than other materials used to make permanent magnets. Being less expensive is one reason ceramic magnets are popular among the permanent magnets. Another reason for ceramic magnet's popularity is the ability to withstand operating temperatures of up to 480°F.

Products Features And Application

Features:

Dimensions: OD220.00 x ID110.00 x 20.00mm Thickness

Tolerances: +/-0.1mm

Material: Ferrite Ceramic C8

Plating/Coating: N/A

Can be magnetized with multiple poles if necessary.

Does not rust.


Key Challenges Of Ceramic Magnet Material

Hard and brittle.

Properties degrade linearly with temperature. At 350°F (177°C), about 75% of room temperature magnetization is retained, and at 550°F (288°C), about 50% is retained. 


Application:

- Speaker Magnets
