KOUEI can answer various requests. What is permalloy, the nickel alloys.

Permalloy is one of the nickel alloys widely used for many applications.

In this page, we will explain about permalloy.

We, the processor and distributor of nickel alloys, can supply products in your requiring shape and quantity as your needs. We can also offer magnetic annealing or supply technical documents, so please contact us.

What is permalloy? And, what kind of products are there in permalloy?

Permalloy is a coined word, not the chemical component “permalloy” originally exists.

The word “permeability” and “alloy” are combined and became the word “permalloy”.

Permeability is not a familiar word, but in other words, it means “tendency to magnetization”.

The permalloy which contains nickel for 45 to 48 percent is called “PB”, “High perm 49®” or “Supra 50®”, and contains nickel for 78 to 80 percent is called “PC” or “Mumetal®”. And we call the permalloy which contains nickel for 36 percent as “PD” or “Invar 36”®, and nickel for 50 percent as “PE”. There is also a permalloy called “PF”, we do not handle though.

Moreover, there use to be “PA”, the high permeability permalloy in the past time.

We handle permalloys not only made by domestic manufactures origin but also foreign manufactures origin. Please ask us freely including the delivery term.

Do not Permalloys get rusted as they are nickel alloy?

Since Permalloy is a nickel alloy

Some metals are easy to get rusted and some are not, how are permalloys?

Many people think permalloy do not get rusted since they have a strong image that nickel alloys do not get rusted.

Permalloys are hard to get rust material as they contain nickel a lot, but sometimes 45 to 48 percent nickel (PB) gets rusted showing like brown spots, not the same as iron’s rust, caused when it is kept in a storage condition as in high temperature and humidity environment.

In package phase, we take rust prevention by putting desiccative or vacuum packing especially for PB processed items.

Since Permalloy is a nickel alloy2

According to customer’s specification, we put coat or electroless nickel plating to prevent rust.

We do not put coat or plating on PC, the permalloy which contains nickel for 78 percent, because PC does not get rusted even in rainy season in the present.

Degradation of magnetism caused by rust.

About magnetic deterioration due to rust

As we mentioned before, permalloy especially PB have possibility to get rusted depending on a storage condition.

Magnetic property is lost by composition break at rusted area, but as for the degradation of magnetic property of whole product is different. Some are mild, some are severe.

We, the manufacturer and seller of permalloy, are supplying products to various fields. Not only magnetic annealing of permalloy, but also we can do surface treatment like coating or electroless nickel plating, or measuring magnetic property.

As the comprehensive manufacturer of nickel alloys, we can answer various requirements from customers.

KOUEI can answer various requests.

which sells nickel alloy permalloy

KOUEI, the seller of permalloys, introduced about permalloy.

Permalloy which has the property of shutting off the effects of magnetic field is often used for magnetic shields. In addition, they are applied for various fields such as noise-cut shield cases for acoustic instrument or measurement equipment, industrial equipment, revolving control unit of invertor motors, cores of transformer and so on.

We can supply permalloys as raw materials. And, we can also process, magnetic anneal, coat and plate permalloy from one piece to millions lot.

We can measure magnetic property or provide technical documents as required, so please ask us freely.
