1. Size D4*6 and D6*4, not the same magnetSourceRare earth magnet-https://www.rare-earthmagnet.com/purchase-the-right-strong-magnets/

Many customers may think this is the same magnet, in fact, many times people make mistakes in the measurement.SourceRare earth magnet-https://www.rare-earthmagnet.com/purchase-the-right-strong-magnets/

Normally we say D4*6MM magnet, that is to say 4mm in diameter and 6MM in height, which is a cylindrical magnet. So we have to pay more attention when we buy magnets, and we will confirm with our customers several times to make sure it is accurate. When they tell us the size of D4*6MM, we usually ask him if the diameter is 4MM and the height is 6MM, while D6*4MM, means the diameter is 6MM and the thickness is 4MM.SourceRare earth magnet-https://www.rare-earthmagnet.com/purchase-the-right-strong-magnets/

There is also need to pay attention to the unit of strong magnets, usually the unit of magnets is millimeter, if the engineer needs 4 * 4cm magnets, and then the buyer tells the supplier that we need 4 * 4 magnet samples, then the actual 4 * 4 mm samples we may receive. So the magnet unit also need special attention.SourceRare earth magnet-https://www.rare-earthmagnet.com/purchase-the-right-strong-magnets/

2、High performance strong magnets are rarely available in stockSourceRare earth magnet-https://www.rare-earthmagnet.com/purchase-the-right-strong-magnets/

As we all know, magnets come in different sizes, different shapes, and different grades. Therefore, it is difficult to store them. Because of the high cost of strong magnets, and if the grade, size, and shape do not meet the needs of customers, it is worthless. Therefore, if you want to buy N52, N50 or N48 magnets in large quantities and the seller says they have them in stock. You should be careful. Because many sellers will use low-grade magnets instead of high-grade magnets.SourceRare earth magnet-https://www.rare-earthmagnet.com/purchase-the-right-strong-magnets/

3、What is the difference between galvanized magnets and zinc-nickel magnetsSourceRare earth magnet-https://www.rare-earthmagnet.com/purchase-the-right-strong-magnets/

Zinc plated magnets or nickel plated magnets many people have this question, what is the difference between them? Simply put, nickel-plated has better performance than galvanized, but galvanized magnets are cheaper. Therefore, choose according to your own product needs. (Nickel has a brighter appearance because it is superior to zinc in terms of polishability. The nickel surface finish also increases the temperature resistance, plus the conductive nature of nickel itself.)SourceRare earth magnet-https://www.rare-earthmagnet.com/purchase-the-right-strong-magnets/
