I am a sales of Alnico factory in China,these days ,a customer visited us,they manufacture microphone,they want to purchase some Alnico magnets used in their microphone.

I think about it,that why Alnico can make the voice better than other magnets,such as Neodymium.If anyone can give me your opinion I will appreciate.

As I know that Neodymium's magnetic values are stronger than Alnico.and do their work temperature is just lower than 150-200C.and Alnico really have best stable magentic performance and temperature stability,but Microphone will not change a lot on temperature as I think.So what made Alnico better than Neodymium on performance of microphone.

 

Thanks

If it is for electronic devices that will be left in cars in the sun (Or built into the cars), like voice activated navigations systems, or cell phones, then maybe the higher curie point of the Alnico is important.

Samarium Cobalt rocks too
