ring magnet neodymium for sound system
Basic Info
Model No.: YY -NEO
Product Description
Ring Magnet neodymium for sound system Product Description 
Physical Properties of Permanent Neodymium Magnet: a) Industrial use of NdfeB magnets was widely for voice coil motors,high performance motors, brushless DC motors, magnetic separation, magnetic resonance imaging, sensors and loudspeakers,etc. b)NdFeB magnets have a moderately high Reversible Temperature Coefficient of Induction which reduces total magnetic output as temperature rises. Selection of NdFeB magnets instead of SmCo, for example, is a function of the maximum temperature of the application, required magnetic output at typical use temperature and total cost of the system. c)NdFeB magnets have some limitations due to their corrosion behavior. In humid applications, a protective plating is highly recommended. Platings which have been used successfully include, parylene,epoxy resin,zinc plating, gold plating, Ag plating,nickel plating and combinations of these platings. Changes in composition and processing over the past several years have resulted in significant improvements in corrosion resistance and high temperature performance.

Packaging & Shipping 
1. By Sea-freight: Magnets would be covered by standard carton box,inside filled with iron shield.If GW is over 500KGS,pallet is required.Shipment schedule would be arranged as soon as possible. 2. By Air-freight: Magnets could be packed by carton box.In addition,magnetism would be shielded through air-freight. Our Services *Payment: For small amount, our usual way of payment is 100% T/T in advance, Western Union or Paypal. For large amount, we also could accept 30% prepayment before production, 70% after fax of Bill of loading. *Delivery time: We can provide scheduled shipments to fit your production schedule.
