Product Name:Use for fastening Motor Magnet
Neodymium arc-segment magnets is one special shape of Rare earth magnets and permanent magnets. It is always manufactured via Wire Cutting and grinding etc. Regular Arc magnets or Segment magnets have the following important factors such as, Outer Diameter Or Outer Radius, Inner Diameter or Inner Radius, Degree of Angle, Thickness, Length, Round Edge etc
Generally speaking, Arc Magnets are all made as Customer Design and as Special requirement.
Our factory produce and manufacture magnets according to customer's design on shape, dimension, grades, coatings etc.
To offer you our Arc magnets price, please offer the following details:
Magnets grade: From N35 To N50, from N Series to UH Series.
Magnets drawing with size and shape and different side view.
Magnetism direction: Mostly magnetized via diameter, if special magnetism direction, please show on the drawing in advance.
Magnets coating: Nickel, Zn, Black Epoxy, AG, Au etc.
Quantities: More mass order quantities. More Lower the prices. Original factory.
