  1) NdFeB Magnets have superior magnetic properties than other magnets
2) Higher unit magnetic properties  
3) Smaller size and lighter weight in designing devices
4) Mostly an iron based alloy, NdFeB type rare earth magnet is much more prone to surface oxidation or rust, and elimination. Users should consider magnet coating, plating or suitable surface treatment
5) Less prone to chipping during handling   6) Lower temperature coefficient of magnetic properties than ceramic, higher than SmCo type rare earth magnet
7) Irreversible loss at high temperature
8) Types: N33, N35, N38, N40, N42, N30M, N33M, N35M, N38M, N40M, N27H, N30H, N33H, N35H, N37H, N27SH, N30SH, N33SH, N35SH, N25UH,   N28UH, N30UH, N35SH, N38, N45, N48, and N50
9) High energy ranging from 8MGOe to 48MGOe with wonderful coercive force    More pictures     YOU PROVIDE We will help you with your order. Usually we ask for the following information. 
• 1) Material type and grade(magnet force) required. 
• 2) Size and shape, if available, a sketch or drawing with dimensions and tolerances. 
• 3) Max working temperature. 
• 4) Delivered magnetized or unmagnetized? Magnetization direction? 
• 5) Quantities required. 
• 6) Coating/plating required (if any) 
• 7) Information on magnet application.   Packaging & Shipping 1. By Sea: As the magnets have strong attraction and we will use the spacer to apart the magnets each other in case people will be hurt when take it out. Then, they will be packed in a white box of pieces each, several boxes to a carton. (Detailed package quantity should be made upon the real products) 2. By Air: If the goods will be shipped by air, all the magnetic should be degaussed and we will use Iron sheet to shield.   Shipping: Express (TNT, DHL, FedEx, UPS, etc), Air, Ocean.
a: The weight is under 40Kgs, we recommend to send them in shielding boxes to you by Express.
b: The weight is between 40Kgs-100Kgs, it can be sent by Express or Air.
c: The weight is over 100Kgs, we recommend to send them by Ocean.     Company information: Company name: HangzhouYangYi magnetics Co., Ltd.   Establish: 2007   Location: Hangzhou City, Zhejiang Province, P.R.
