50 x 5mm Rare Earth Disc Magnets , Rare Earth Magnets in China | N42 Magnets
There have two types of rare earth magnet, neodymium magnets (NdFeb) and samarium cobalt (SmCo) magnets.
There have also many different grades of each, all of which have different properties.
The greater force exerted by rare-earth magnets creates hazards that are not seen with other types of magnet.
Magnets larger than a few centimeters are strong enough to cause injuries to body parts pinched
between two magnets or a magnet and a metal surface, even causing broken bones.
Factory production advantages:
1. OEM and ODM assistance:
More than 12 years professional factory production line for OEM and ODM magnet solutions,
thousands of molding tools available for your customized magnet design, you think it, we make it for you.
2. Measuring of magnet:
Quality is our culture, all our products is coming with good quality finished and Demagnetization curve as well as we have special team work for after sales services.
3. Testing for customer’s magnet:
We know most of customers have not much professional equipment for their magnet testing, But do not worry, we can free of charge help you test if it is true.
When you buy magnets with a very lower price, or you think something is not good when use the magnets, you can ask us for help, we will do the professional testing and let you know what you get.
4. Fast and safety delivery
We have worked with some experienced Express courier and Sea shipper more than 10 years, we can guarantee every process of your magnet order from materials, design, production, testing to delivery, we really do all care.
5. Suggestions and feedback
We love customers and love to hear from you whether it's feedback or questions about our Quality, Service, Market, etc, we will continue improving our performance and together we are stronger.
