N35 N38 N40 N42 N45 N48 N50 N52 Strong Small Round Neodymium Magnet for box
Disc and Cylinder magnets are defined by two dimensions: diameter and thickness. To be consistent, we define the Thickness dimension along the axis of magnetization. The thickness is usually the smallest dimension, but not always!
We’re sometimes asked if we can provide disc or cylinder magnets magnetized through diameter. Yes, we can do it,we defined it diametrically magnetized.
Neodymium Magnet Tech Parameter:
Disc magnets with different coatings
Magnetism-shield(with foams and metal pieces) for express delivery or air delivery
Regular package,small inside box and cardboard carton box for sea shipping.
1 Small Round Neodymium Magnet information
1) Size ( Diameter* Thickness), in mm or Inch
2) Surface Coating (Normal is Zn, NiCuNi)
3) Grade, ( Normal is N35, or higher grade requirement)
(Higher grade, Strength stronger, also Price higher)
4) Magnetised direction (Normal is axially magnetised)
5) Woring tempreture, (Normal temperature or special temperature)
(Tell us the quantity for us to estimate is weight, then can select suitable express) company)
7) Expect arrive time
(warehouse to door or door to door service, or special Fast Delivery Service)
2 Manufacture Ability
1) Diameter, from 1mm to 80mm, usually 3mm to 50mm (1 inch=25.4mm)
2) Thickness, from 0.5mm to 60mm, usually 1mm to 5mm
3) Tolerance, ±0.1mm, ±0.05mm for selection.
4) To some high working tempreture ,or higher grade , or radially magnetised magnet,
We also can manufacture in high cost-performance radio, small quantity also welcome.
3 Manufacture Time

to N38H radially magnetised disc/cylinder magnet
size below 4.5mm，we usually finished in 12-15 days after received deposit;
to other size radially magnetised disc/cylinder magnet
usually finished in 18-20 days after received deposit
2) Also, we supply Fast delivery Service for selection.
4 About Express:
1) warehouse to door service, usually need 7-9 days to your address
it also need 2 days for us to send magnets to warehouse
so, totally it need 9-11 days for u to receive magnets after we sended out.
Fedex, DHL,UPS,TNT,ARMAX, price cheaper than door to door service,
We applied for 20% discount
2) door to door service, usually need 4-7 days to your address,
use DHL service, its suitable for package above 20kg
if value of goods above 1000 dollars, need customs clearance, it need addtional 1-2 days
we applied for very good discount. Also, you can use your own DHL account.
