Strong Magnet Manufacturer Tells You: Neodymium-Iron Boron Permanent Magnets, also known as the "MSG of Modern Industry," are a key high-functional magnetic material driving the advancement of technology and society. Widely used across various fields, how to judge the advantages of permanent magnet products: magnetic properties; magnet size; surface coating.

Magnetic Function: Primarily, the key to decision-making is the magnetic properties of the raw materials controlling the production process.

1. Raw material producers may choose to produce medium-grade or low-grade sintered neodymium-iron-boron based on business needs, following the standard rules for purchasing raw materials. Our company exclusively sells high-grade neodymium-iron-boron.

2. The advancement in production technology also determines the functional quality of the magnets.

Quality control during the production process is very crucial.

Magnet Shapes and Tolerances: Various shapes of neodymium-iron-boron magnets are used, including round, irregular, square, tile, and trapezoidal. Materials of different sizes are processed using different machine tools with rough machining, with the technology and machine operators determining the product's precision.

Surface Coating Treatment: The quality of surface coating, including zinc, nickel, nickel-copper-nickel electroplating, copper, and gold electroplating techniques. We can perform electroplating options on products as per customer requests. The quality of neodymium-iron-boron products can be briefly summarized as mastering the functionality, controlling dimensional tolerances, and evaluating the appearance of the coating through visual inspection. Examine the Gauss surface of the magnet's magnetic flux, etc.; dimensional tolerances, which can be measured with the precision of a caliper; coating, including the color and brightness of the coating and the bonding strength of the electroplating, and observe the surface finish of the magnet for smoothness, stains, and any chipping or corner loss to evaluate the product quality.

Magnets are not actually made entirely from a mixture of primary materials like neodymium, iron, and boron that are broken down and sintered together. Once this process is complete, our magnet raw materials are ready. The raw materials primarily come in two types: round and square shapes. The required dimensions are cut from larger rough blanks using slicing machines. After cutting, the surface treatment, which is electroplating, is applied to the magnets. Electroplating is done to prevent corrosion and rust, which has no relation to the magnetic force. Even after electroplating, the magnets are still not magnetic. They need to be magnetized using a magnetizing machine, resulting in the strong magnets we see.
