Product Name:Disc Countersink NdFeB Magnet N52
Model No:NCD-2045-N52
1. Powerful permanent pot magnet
2. High quality & best price
3. High working temperature
4. Good corrosion resistance
Original Manufacturer:HangSeng Magnetech
Solution:Customized your required material, size, coating, shape, grade, pull force and woking temperature
Origin:Ningbo, Zhejiang, China
Supply Ability:50000pcs/day
Applications:magnetic holding, lifting, antenna Mounting, positioning, retrieving and much more.
1) Made of iron, steel with sintered ferrite, sintered NdFeB and cast alnico gluing together
2) Sintered ferrite pot magnets and cast alnico pot magnets maintain their magnetic properties under extreme heat conditions, and are ideal for industrial requirements
3) For daily life use as holding magnets
Pros: Very strong hold when contacting another magnet or plain iron, very difficult to pull away (easy to slide however).
Pretty strong hold between two of these even with a couple of mm in between.
Cons: Would like thicker (and more powerful) versions. Sure u can stack these together but sometimes it’s not the same thing.
Other Thoughts: Good for attaching thick stacks of paper to refrigerators etc or pinching together papers or textiles.
Bottomline: This is the one if you need strong cost-effective magnet.
