Since neodymium magnets generate more magnetic drive than ferrite at the same weight, a neodymium magnet matched for this specific speaker driver’s measurement will likely be smaller. However, exterior of the above talked about reported variations in how every kind of magnet generates waves of power (and the way the shape of these differ) by way of precise magnetic power theoretically each could obtain the identical figure. The ferrite magnet can be bigger.
We carry a wide range of AlNiCo Magnet Suppliers grade eight disc magnets in inventory, not all of which are shown on this website. Alnico magnets are part of the permanent magnet family, and comparatively high in magnetic energy. They offer excellent temperature stability & can be utilized at temperatures as much as 1000⁰F (500⁰C). Because of their temperature stability and relatively high magnetic power, they are generally used for industrial functions akin to rotating machinery, meters, devices, sensing devices holding applications and more.
Solid Alnico 5 – This is the mostly used. This alnico materials is used extensively in rotating equipment, meters, devices, sensing gadgets, and holding purposes, to name a couple of. For finest outcomes with alnico 5 magnets, the length should be no less than 5 instances the cross-section diameter; or 5 occasions the diameter of a circle equal in space to the cross part.
If required, the magnets are floor to finished size. The as solid look of Alnico is a darkish gray/black colour with a roughened texture (the texture is from the sand mold). The machined finish is a clean brilliant metallic colour. There isn’t any detriment to the magnet’s efficiency is the non pole faces are left as cast (this is cheaper) though some clients might choose all the faces to be machined for aesthetic causes. If wanted, the magnets are additionally magnetised before packing.
