permanent magnet , Powerful N52 Block NdFeB Neodymium Magnets
Always dispose of rare earth powder with care. Do not risk fires.
Disposal of magnetized magnets must be done correctly so as to prevent injury when handling.
Our core competitive ability:
1. what about new magnet project consulting:
a. our engineers will be always here to help, just send your product details,
we will evaluate and give the best solution to you in short time.
b. we will keep Non-Disclosure Agreement for each new design project.
2. what abou the quality:
(a) BH curve, Demagnetization curve report for check when shipping
(b) Flux density, measurement is made by Gauss / Tesla meter
(c) Pull force measurement by mechanical method
3. what about customer's special requirement:
(1) Tolerance, between +/-0.05mm and +/-0.2mm as per magnet application
(2) CNC and assembly, we have great machining center for the process
(3) Plating, Ni-Cu-Ni, Grey Nickel, Epoxy, Silver, 24K Gold, etc,
other special Rubber Coated, Phosphatsing, Parylene, Customized coating.
4. what about the shortest lead time:
Generally speaking, we have raw materials in our stock, Such N35, N38, N40, N42, N52
5. what about the shipping:
We have worked with some experienced Express courier and Sea shipper more than 12 years,
we can guarantee every process of your order from materials, design, production, testing to delivery, we really do all care.
