Soft magnetic iron is a high-quality special magnetic steel with an iron content of over 99.5%. Its unique features include low coercive force (Hc), high permeability (μ), and high saturation flux density (Bs), making it ideal for applications that require high magnetic flux density under static low-field and low-frequency conditions. The material has high purity, a dense structure, and uniform organization, which makes it suitable for high-vacuum and magnetically stable applications. It can be easily processed using various mechanical methods, such as turning, punching, bending, and welding, and has excellent surface quality after processing. Our pure iron products are typically coated with a protective layer to prevent corrosion. Without this coating, pure iron may be susceptible to corrosion over time.

Note:
  • 1: B5, B100, and B10000 represent the B values under conditions of H=200A/M, H=1000A/M, etc.
  • 2: Pure iron DT8 has a vacuum leakage rate of ≦1X10-9Pa.m3/s.
  • 3: The vacuum leakage rate of pure iron DT9 is better than that of pure iron DT8. Customers can conduct their own experiments to check.
  • 4: The magnetic flux density values shown in the table represents the technical potential for each grade of pure iron and are for reference only. The actual value is closely related to other factors such as batch composition and heat treatment process.

Main Products
Q&A
No, we don't. Generally, our products are customized according to customers' requirements. We can assist our customers in designing approximate dimensions based on their product usage.
Yes. Please let us know and we will send them to you with your order.
As our magnets are machined, not molded, there is no minimum order quantity. We can produce even just one piece. However, the production cost varies, so the unit price for a small quantity may be higher.
Since all of our products are customized, normally we do not keep extras in stock. Therefore, we may need to make new samples when customers request them, which incurs additional costs. We may provide free samples only if we happen to have the product in stock.

We accept cash, wire transfer (T/T), and letter of credit (L/C), with wire transfer being the preferred method. For small orders, infrequent annual orders, or initial order, payment is required before shipment. Once the trust has been built, we can consider monthly billing.

It depends on the product's performance, size, shape, and quantity. In general, the lead time is around 30-40 days if we have readily available raw materials. For special specifications, grades, or large quantities of products, please confirm the lead time with our sales representative when placing your order.

To test the performance of soft magnetic materials, we follow these steps:

  • We take samples from the same batch of raw materials used to manufacture the product and process them into sample rings.
  • We anneal the sample rings and the soft magnetic product together in a hydrogen annealing furnace.
  • We use a soft magnetic tester to test several sample rings from the furnace to obtain the results.
  • We analyze all the data and determine if the material is qualified.

Our packaging methods mainly include standard cardboard box packaging and wooden crate packaging. We can also customize packaging methods according to customers' requirements. All packaging methods provide good protection, but the classification is based on customers' applications and the product size. For example, oversized products cannot be packed in cardboard boxes.
