You can't tell from the appearance. The isotropic when pressing (dry pressing or wet pressing), there is a magnetic field, so that the easy magnetization axis of the magnetic powder is aligned. The anisotropic is about 3 times more than the isotropic one. The isotropic is easier than the anisotropic when making. Therefore, the tooling cost and unit price of the isotropic magnets is cheaper, but the magnetic force is much weaker. Our advantage: 1. High cost performance: We have advanced technology and equipment, high-quality products and services, and reasonable prices. Especially the quality has also been recognized by customers and received unanimous praise from customers. 2. High stability: We have adopted advanced technology and equipment, and the products show extremely high stability during use, which can meet customers' requirements for high stability. 3. Wide application: Our products can be widely used in electronics and electro-acoustic, communication, medical, automotive and other fields, and provide customers with comprehensive solutions, which can be customized according to customer needs, so as to provide the best plan. 4. High precision: We adopt advanced production technology and equipment to ensure the high precision of the product. 5. Fast delivery: We have a complete production process and logistics system, which can deliver quickly to meet the urgent needs of customers, and we can provide professional technical support and after-sales service. The team members have rich industry experience and can provide customers with targeted solutions and services.
