Metal Powder

Metal powder refers to a group of metal particles with a size less than 1mm, including single metal powder, alloy powder and certain refractory compound powders with metallic properties. It is the main raw material of powder metallurgy.
Elemental metals are generally silver-white. When the metal is under certain conditions, it becomes black powder. Most metal powders are black.

We can provide nano-processing services for various raw materials, process and customize products of different particle sizes according to user requirements, and provide technical solutions for corresponding product development.

Metal powders include aluminum powder, copper powder, iron powder, nickel powder, titanium powder, tungsten powder, molybdenum powder, etc. Metal powder has good formability, high sphericity, good dispersion performance, small particle size, uniform distribution, and has good It has excellent anti-corrosion properties and is not easy to evaporate or burn. It can be stored for a long time and is environmentally friendly. Widely used in automotive, aerospace, electronics, machinery and construction fields.

How do you make metal powder?

Usually according to the principle of transformation, it is divided into two categories: mechanical method and physical chemical method. It can be obtained from solid, liquid and gaseous metals by direct refinement, and it can also be transformed from metal compounds in different states through reduction, pyrolysis and electrolysis. Preparation. Carbides, nitrides, borides and silicides of refractory metals can generally be produced directly by chemical combination or reduction-combination methods. Due to different preparation methods, the shape, structure, particle size and other characteristics of the same powder often vary greatly.

Powder properties

Metal powder is a loose substance, and its properties comprehensively reflect the properties of the metal itself, the properties of individual particles, and the characteristics of particle groups. Generally, the properties of metal powders are divided into chemical properties, physical properties and process properties.

Chemical properties refer to metal content and impurity content.
Physical properties include the average particle size and particle size distribution of the powder, the specific surface area and true density of the powder, the shape, surface morphology and internal microstructure of the particles.
Process performance is a comprehensive performance, including powder fluidity, bulk density, tap density, compressibility, formability and sintering dimensional changes, etc.

In addition,
For some special purposes, the powder is also required to have other chemical and physical properties, such as catalytic properties, electrochemical activity, corrosion resistance, electromagnetic properties, internal friction coefficient, etc.
The performance of metal powders depends to a large extent on the production method of the powder and its preparation process.
The basic properties of powders can be determined using specific standard testing methods.
There are many methods for measuring powder particle size and distribution, generally using sieve analysis method (>44μm), sedimentation analysis method (0.5~100μm), gas transmission method, microscopy method, etc. Ultrafine powders (<0.5μm) were measured using electron microscopy and X-ray small-angle scattering.
Metal powder is customarily divided into five grades: coarse powder, medium powder, fine powder, micro-fine powder and ultra-fine powder.

What is metallic powder used for?

Metal powder can be used as raw material for powder metallurgy products or can be used directly.
Industrial raw materials:
The metal powders used in this area mainly include iron, tungsten, molybdenum, copper, cobalt, nickel, titanium, tantalum, aluminum, tin, lead and other powders. The consumption accounts for more than 2/3 of the total metal powder production.

The Direct Applications of Metal Powders are Very Wide.

For example:

1. Iron powder for welding rods and flame cutting processes.
   2. Ni-Cr-B-Si, Fe-Cr-B-Si, Co-Cr-W and other alloy powders for spray coating, spray welding and fusion welding, as well as nickel-clad aluminum or alumina, nickel or cobalt-clad tungsten carbide welding, etc. Powder. Used to enhance the wear resistance, heat resistance and corrosion resistance of the workpiece surface.
   3. Ultra-fine aluminum powder for rocket solid fuel.
   4. Use nickel, iron and cobalt powder as catalyst.
   5. Magnetic powder for clutches, audio tapes, and copiers, such as iron-based alloy powder.
   6. Iron, nickel, cobalt, manganese, magnesium, aluminum, aluminum-magnesium alloy and other powders for fireworks.
   7. Aluminum, magnesium, iron powder, etc. are used as deoxidizers, chemical reagents, metal thermal reducing agents, displacement agents, etc.
   8. Aluminum, copper and other powders for surface coloring, decoration, coating pigments, and paints.
   9. Steel shot, bronze shot blasting, etc. for surface treatment.
   10. Iron powder and copper powder for metal electrochemical deposition.
