Unlocking the Power of Innovation: Introducing NGYC's Supermalloy – The Ultimate Iron-Nickel alloy

Our revolutionary Supermalloy, a soft magnetic Iron-Nickel alloy, redefines industry standards with its remarkable properties and versatility. Crafted with precision, Supermalloy boasts an adjustable nickel content ranging from 30% to 90%, making it the ideal solution for a multitude of applications across various industries. It is widely used in the fields of electronic communication, precision measurement, rectification devices, magnetic shielding components, relays, transformers, inductors, and electromagnetic clutches.

Features
  • High magnetic permeability, low losses, and low magnetostriction. Components made from Supermalloy exhibit strong saturation resistance, high inductance, excellent stability, and compact size, ensuring energy efficiency.
  • Superior processability with excellent surface quality and exceptional welding properties. However, it's important to note that the magnetic properties of Supermalloy, particularly its permeability, are sensitive to mechanical stress. After annealing, caution should be exercised to avoid collisions or bending, thereby minimizing the generation of excessive installation stress.
  • With a higher nickel content, Supermalloy offers good corrosion resistance in general environments. In particular, high-nickel Supermalloy often doesn't require special rust-proof treatments such as coating.
  • Supermalloy comes in various grades categorized by composition: 35% to 40% NiFe alloy, 45% to 50% NiFe alloy, 50% to 65% NiFe alloy, and 70% to 81% NiFe alloy. Each category allows for adjusting the magnetic hysteresis loop state of the raw material through process parameters, providing flexibility for users to choose based on their specific requirements.

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.
