Audio Claims About Neodymium Magnets
Since neodymium magnets generate extra magnetic drive than ferrite at the identical weight, a neodymium magnet matched for this explicit speaker driver’s measurement will likely be smaller. Nevertheless, outside of the above mentioned reported differences in how each kind of magnet generates waves of pressure (and the way the form of those differ) when it comes to precise magnetic force theoretically both may obtain the same figure. The ferrite magnet could be larger.
We carry a variety of alnico grade 8 disc magnets in stock, not all of that are proven on this web site. Alnico magnets are a part of the permanent magnet family, and comparatively excessive in magnetic energy. They provide excellent temperature stability & can be used at temperatures up to 1000⁰F (500⁰C). Because of their temperature stability and comparatively excessive magnetic strength, they are commonly used for industrial applications similar to rotating equipment, meters, devices, sensing devices holding applications and more.
Forged Alnico 5 – This is the mostly used. This AlNiCo Magnet Suppliers materials is used extensively in rotating equipment, meters, instruments, sensing gadgets, and holding purposes, to call a few. For finest outcomes with alnico 5 magnets, the length should be no lower than 5 occasions the cross-section diameter; or 5 times the diameter of a circle equal in space to the cross section.
If required, the magnets are ground to finished dimension. The as forged look of Alnico is a darkish grey/black color with a roughened texture (the texture is from the sand mold). The machined finish is a smooth shiny metallic color. There isn’t a detriment to the magnet’s performance is the non pole faces are left as cast (that is cheaper) though some clients might want all the faces to be machined for aesthetic reasons. If wanted, the magnets are also magnetised earlier than packing.
