Characteristics and application of Sagwell superfine cobalt powder

Sagwell recently launched an superfine Cobalt Powder,grade F1-Co, with a cobalt purity of up to 99% and an oxygen content of less than 0.5%. Today we will talk about the characteristics of this superfine cobalt powder.

First, let's talk about the concept of "superfine". From the perspective of particle size, any powder within 10μm can be called superfine. In the past, customers often asked what the characteristics of "superfine" powder are and why it is so much more expensive than coarse powder. Sagwell took superfine cobalt powder as an example and analyzed several powder characteristics:

1. Specific surface area:

Generally speaking, the finer the powder, the larger its specific surface area, and the larger the specific surface area, the greater the surface energy.

2. Magnetism:

The smaller the volume, the stronger the magnetism. Cobalt powder has good magnetism and is magnetic even if it is not magnetized within 1150°C.

3. Activity:

From the perspective of sintering usage scenarios, the finer the powder, the higher the sintering activity and the finer the texture.

Now let's talk about the application of this superfine cobalt powder. In tool applications (diamond, carbide), the most obvious effect of cobalt on the matrix is ​​to enhance performance and improve stability.

How does it perform in other industries?

1. Special tool industry:

Mainly used in fields that require special materials, such as wear-resistant parts, which require high impact resistance, high toughness, good tear resistance, and the ability to withstand high-intensity attacks.

2. Battery industry:

The lithium battery, power battery and other industries have huge demand for cobalt. With the vigorous development of the current new energy industry, this demand is expected to further expand.

3. Magnetic material:

Ultrafine cobalt powder has low resistivity, low magnetic saturation and strong anti-interference ability.

Superfine cobalt powder can also be used in catalysts, high-temperature alloys and other fields.

During the communication process with customers, Sagwell technicians will recommend suitable powders based on the specific conditions of the customer's terminal products, equipment, etc. Please contact us for more details.
