The sintered NdFeB adopts powder metallurgy process, and the production environment of the previous blank is a vacuum environment, because the metal neodymium is an easily oxidized substance.
1. Incoming inspection of raw materials
The content, precision, weight and appearance of crystal particles are mainly detected.
2. Raw material processing
Raw material treatment is to remove some useless substances on the surface of raw materials; neodymium: remove oil, oxide scale, slag, and make it dry; iron: remove rust, and make it dry; boron: remove the rust color in ferroboron.
3. Ingredients
Main raw materials: Nd neodymium (about 34%), Fe iron (about 65%), B boron (about 1%).
Additives: (additives) Dy dysprosium, Al aluminum, Nb niobium, Ga gallium, Mo molybdenum, Co cobalt, Cu copper, etc.
The ingredients are mainly based on the performance requirements, and the required components are proportioned. The proportions of the main raw materials with different properties are different. The higher the Br (remanence), the higher the content ratio of metal neodymium, the Hcj The higher the product (intrinsic coercivity), the higher the proportion of rare earth metals in the additive.
4. Smelting
The purpose of smelting is to dissolve the metal blocks of the raw materials into a liquid state in a high temperature environment through the "vacuum melting furnace" equipment, and then cast them into alloy blocks of 250*150*18mm after being fully mixed; 1500 ℃, smelting neodymium, boron and other components, the temperature is 600-700 ℃; the smelted alloy material is square shape, the weight of each smelting is 30Kg or 50Kg, and it takes 2-3 hours.
5. Milling
"Coarse crushing - jet mill": This process is commonly known as "pulverizing process". This process is carried out in a low oxygen environment, because "neodymium" will oxidize when encountering oxygen. The "ingot" milling process is used for medium and low-performance products, and the "belt-throwing" milling process is used for high-performance products.
The pulverizing process is in a vacuum environment, and it is necessary to add hydrogen and nitrogen (to protect the raw materials from oxidation), and add an antioxidant to prevent oxidation. It can produce 100Kg each time, and it takes 10 hours; after the pulverization is completed, an appropriate amount of gasoline will be added to the nitrogen environment. , used for bonding.

Product Information
Neodymium Arc Magnet is a unique curved shape of sintered Neodymium Magnets, made from an alloy of neodymium, iron and boron. Plated with triple layers of NI-CU-NI(Nickle-Copper-Nickle) for strong corrosion protection, neodymium Arc Magnet pieces can form a circle with certain measurements, and it is usually used for both rotor and stator in motors, generators, or magnetic coupling devices. Arc magnets are typically magnetized through diametrical direction and used in pairs in high temperature working environment.
Machining process of arc magnet is relatively more complicated compared to other shapes of neodymium magnets. We utilize various advanced machining methods based on the dimension, productivity, efficiency rate and processing cost. Wire-cutting method has proven to be one of the most advanced methods for Special Shaped Magnet like arc magnets. Our factory is well equipped with automated wire-cutting machines and a strong R&D team that is ready to assist our customer with any requirement they may have.
