Powerful cube magnets are usually made of neodymium rare earth materials.
All grades from N35 to N52 are suitable for neodymium-powerful cube magnets.
From small 1mm cube magnets to large and strong cylindrical magnets of 50mm, every grade is possible to use.
The common powerful neodymium cube magnets for sale are 3mm, 5mm, 7mm, 8mm, 10mm, 12mm, 15mm, and are shipped regularly.
Rubber and plastic waterproof coatings can be used for strong neodymium block magnets in addition to electroplating coatings.
The small 3x3x3mm cube magnet is made of neodymium rare earth, which makes it very powerful. It is coated with a rust-proof coating to increase its durability. The magnetic pull of 3mm cube magnets ranges from 0.63 LB to 0.93 LB, depending on the grade. Small but strong rare earth neodymium cube magnets of 3mm are used to make crafts.
The small 5x5x5mm cube magnet is made strong with neodymium elements. Its magnetic pull on steel plates ranges from 2.1-3.1 Lb, depending on the N35 to N52 grades. Nickel, gold, silver, and epoxy resin are common surface coatings for 5mm cube magnets. You can use small but strong 5mm neodymium cube magnets to make magnetic toys and jewelry.
The neodymium iron boron alloy makes the 7mm small cube magnet powerful, with a magnetic pull on steel plates ranging from 4.33 lbs to 6.43 lbs. However, magnetic materials are not rustproof, so we usually provide nickel-plated 7mm rare earth neodymium cube magnets, and other coatings such as epoxy resin and gold are also popular coatings. You can use a 7mm strong neodymium cube magnet as a magnet pin for whiteboards and refrigerators.
The cube magnet measures 8x8x8mm, and its strength is surprisingly powerful due to neodymium. The magnetic pull of N35 8mm neodymium cube magnets on steel plates is 5.67 LB, and the magnetic pull of the same size N52 cube magnet is as high as 8.43 LB. The perfect size and ideal magnetic force make 8mm neodymium disc magnets the best-selling cube magnets.
10mm is the most popular size in the neodymium cube magnet family and is also the best-selling cube magnet for many distributors. Magnetic cubes 10mm have a magnetic pull on steel plates of up to 13.77 pounds for N52. Even N35 cube magnets are strong enough for most purposes. For ease of separation, we offer neodymium cube magnets of 10x10x10mm with plastic spacers.
12mm is one of the most popular sizes in the neodymium cube magnet family. The 12mm neodymium cube magnet has a complete range of grades, and the magnetic pull of the magnet on steel plates ranges from 13.62-20.24 pounds. The strong magnetic force makes the magnet widely used in different fields. For ease of use, all 12x12x12mm neodymium cube magnets come with plastic spacers. Depending on the grade of the material, they can withstand a temperature range from 80℃ to 230℃.
15mm is one of the most popular sizes in the neodymium cube magnet category, offering a complete range of grades. The magnetic force of 15mm neodymium cube magnets ranges from 21.21 pounds to 31.51 pounds, depending on the grade. Our neodymium cube magnets of 15x15x15mm come with a plastic spacer between them for easy separation. However, handling such a powerful 15mm neodymium cube magnet still requires caution.
Neodymium iron boron is the main component of this 20 x 20 x 20mm cube magnet. If you need cube magnets with magnetic forces between 17-25 kg, the 20x20x20mm neodymium cube magnet is relatively ideal, with a pull force on steel plates of 37.5-55.7 LB. They usually have a nickel-copper-nickel coating. Our 20 x 20 x 20mm neodymium cube magnets are delivered with thick plastic spacers so that you can easily separate them. However, you still need to handle these super-strong cube magnets with care.
