Rest the requirements of the magnet is very simple, which is able to absorb the cutting tool, cutting tool. But the reality! Rest is everyday items, need to promote, take market share. A vicious price competition is a commonly used means of merchants. In order to make profit space, it is only natural that the operation on the rest of spare parts. The inside of the magnet has a big knowledge. The characteristics of ndfeb material is hard and brittle, after magnetizing of weight is more than 600 times their own weight, absorbs knock against. And can't use the magnet for magnetic separation. Usually knock against, lead to wear and tear, dept. of damaged parts due to the loss of coating, oxidized, has led to the loss of magnetic force. First rest is with strong magnetic ndfeb magnet, strong magnetic is always strong magnetic, preliminary already high suction, high magnetic table. So ndfeb easy to corrode, general coating requirements are either galvanized or nickel plating. Galvanized iron with plating NieDou is the silver-white metal, but more shiny nickel plating with corrosion resistant, at the same time the cost will be higher. And rest a magnet is built into the inside, so the natural choice galvanized in order to reduce the cost. Right! Above all, anyway, N28 N33 and N35 is strong magnetic, as long as to absorb the cutting tool with respect to OK. Natural someone choose desperate custom N28, N33 material. As a small make up in the magnet industry, it is necessary to say with you. N28, magnetic N33 table is very strong, but very stable. Maybe two months or three months began to appear demagnetization phenomenon, optimism is half a year. Can you imagine when you cook in the kitchen knife due to absorb not fall down? Drawing on the magnet for N35 / F30 * 30 * 10 mm/nickel plating. So, choose the magnet supplier, first there was the word of mouth is important, then is the delivery date, unit price that can slowly to discuss. Again, you get what you pay for. Dongguan rich magnetoelectricity technology co. , LTD. , welcome to visit the factory. PS: : about 30 - magnet head price After 60 yuan, the cutting tool with the cleaning directly on waterlogging caused by excessive rainfall rack, such as income rest again after it dry naturally, do not use brush a bowl.
