Strontium Ferrite

Ferrite magnet is widely used for automobiles, motors, consumer electronics, aerospace, and other high-tech fields. Because ferrite magnet has good temperature resistance and low prices, it has become the most widely used permanent magnet. The most common types of ferrite magnets are anisotropic strontium, anisotropic barium, and isotropic barium magnets. We are an ISO/TS 16949:2002 certified manufacturer and have more than 8 years of manufacturing experience and export experience for 12 years. We offer various products including isotropic and anisotropic ferrite magnets. We also provide customer design service for you.

* 1
Q) Is your company a magnet factory or a trading company?
A) We are one of the leading magnet manufacturers in Xiamen. Welcome to visit our factory.

* 2
Q) Is the quality of the magnet guaranteed?
A) Yes, we can guarantee that the magnets we ship to you are 100% of the good quality magnets you ordered. If there are any product quality problems or product damage during transportation, we will take 100% responsibility for you and you can ask for a refund or replacement of the relevant products.

* 3
Q) How long does it take to produce and ship?
A) It takes about 7-10 working days for ordinary magnet orders, and about 25-35 working days for custom projects. In addition, the fastest production time for urgent orders is 3 working days.

* 4
Q) How does the class and size of the magnet (length x width x height) affect the Gaussian energy level of the magnet?
A) Magnet size is the same, the higher the grade, the higher the gauss;
Same magnet grade, same surface area, thicker, higher gauss;
Same magnet grade, same thickness, larger surface area, lower gauss;

* 5
Q) What does pull mean?
A) Pull is a measure of magnetic force. It is the force required to remove a magnet parallel to a solid magnetic surface, such as a steel plate.

* 6
Q: If I put two neodymium magnets together, do they double their strength?
No. It's going to get a little smaller. For example, two magnets with a single pull of 50 pounds have a combined force of 90 pounds when they stick together.

* 7
Q) Does the strength of neodymium magnets decrease over time?
A) They do not lose any strength naturally and maintain it permanently under normal conditions, unless temperatures exceed 80 degrees Celsius (ºC) and then gradually lose strength.
