Black Iron Oxide Magnetic

Our Black Iron Oxide Magnetic is one of our core products. It is a black crystal powder with magnetic properties and good electrical conductivity. Customers use this material in magnetic materials, electronic components, and battery materials.

Unlike common iron oxides, this product offers high purity and uniform particle size. These characteristics make it stable for large-scale industrial production. It helps minimize batch-to-batch variations during manufacturing. This material is designed for high-end applications that require precision, reliability, and consistent performance.

Our product contains 95% to 98% magnetic iron oxide. The 105℃ volatile matter does not exceed 1.5%. Water-soluble matter remains below 0.5%, and the 38.5μm sieve residue is less than 0.3%.

These specifications demonstrate excellent thermal and chemical stability. Our factory has operated for 5 years with mature production processes and a complete quality control system.

Our quality management includes three stages: incoming material inspection, in-process monitoring, and finished product testing. We perform 100% visual inspection and batch performance testing before shipment.

Our R&D team consists of 15 professionals, all with bachelor's degrees or above. The team leader is a Hangzhou Class D talent with postdoctoral experience.

Our standard production cycle is 7 to 15 days, depending on inventory status and order quantity. For repeat orders, we can shorten delivery time by approximately 5 to 10 days.

We accept third-party inspections, and the inspection cost is covered by the requesting party. Our products strictly follow national standards to ensure reliable quality.

We have built long-term customer trust through stable product performance and on-time delivery. The high purity and magnetic properties of this material make it suitable for demanding industrial applications.
