Global Gas Atomized Alloy Powder market trend 2025-2028 Comparison of the Performance and Cost of Water Atomized and Gas Atomized Alloy Powder by Newsb-house

As the world deals with potential supply shortages, oil prices are soaring again, with more dramatic spikes and sudden drops expected.

For consumers, that means more expensive gas for longer - prices at the pump remain above $4 a gallon. For the economy, that means more inflation. In addition to the pressure on consumers, any business that relies on oil -- from airlines and truck drivers to chemical companies and plastics producers -- will face higher costs.

Mr Pickering estimates that 2m to 3m barrels a day of Russian oil shipped by water are frozen out of the market with no direct buyers. Due to the soaring oil price, the price of the Gas Atomized Alloy Powder in the chemical industry will also be greatly affected. He said China and India are continuing to buy Russian crude. "I'm sure there will be others willing to take on more over time," he said. Mr Pickering said he did not expect oil to return to $130 a barrel, but added that it could happen. Francisco Branch, head of commodities and derivatives at Bank of America, said the US market was ready for cyclical price spikes and price swings in the Gas Atomized Alloy Powder.

The powder preparation method in which a fast-moving fluid (atomizing medium) impacts or otherwise breaks the metal or alloy liquid into fine droplets and then condenses into a solid powder is called the atomization powdering method. At present, the most widely used powdering technology is water atomization and gas atomization. Although the principle of powdering is the same, the physical properties of the powders produced vary greatly.

shape

Since the heat capacity of gas is smaller than that of water, when gas atomization is used, the alloy receives a low degree of chill. When the atomization medium is impacted, the alloy liquid atomized into fine droplets will not solidify immediately, which gives the alloy The time for the droplet to shrink into a ball during the falling process, so it is easy to obtain spherical alloy powder. When water is atomized, the situation is just the opposite. Due to the chilling effect of water atomization into fine alloy droplets, it solidifies into alloy powder almost in an instant. This makes the alloy powder formed by alloys with lower surface tension appear as potatoes. Only those alloys with high surface tension, such as nickel-based alloys, can be made into spherical alloy powders. By adjusting the atomization parameters and the superheat of the alloy liquid during atomization, water atomization can also be used to produce approximately spherical alloy powders to meet the needs of thermal spraying.

chemical composition

No matter whether it is water atomization or gas atomization, the chemical composition of the alloy powder produced will not be different due to the different production methods.


Microstructure

The alloy powder made by gas atomization has a much lower degree of supercooling than that made by water atomization. Therefore, the metallographic structure of the alloy powder made by different atomization methods with the same chemical composition will be different.


Oxygen content of alloy powder

The oxygen content of the alloy powder is related to the sensitivity of the alloy itself to oxygen and the oxygen content in the atomization environment during atomization. If the alloy itself is very sensitive to oxygen, not only should measures be taken during atomization, it is best to use vacuum melting during melting. For most alloys, as long as the contact with oxygen is reduced during atomization, the purpose of reducing the oxygen content in the alloy powder can be achieved. During gas atomization, nitrogen is usually used as the atomization medium. A large amount of nitrogen fills the atomization area and drives out the oxygen in the atomization area, so it can protect the alloy droplets from being oxidized during atomization and cooling.


When a molten alloy liquid is atomized into metal powder, its surface area increases countless times at the moment of atomization. In other words, its area combined with oxygen increases, and more metal surfaces are exposed to it. In the fogging environment. Therefore, if no measures are taken during water atomization, the oxidation of the alloy droplets cannot be avoided. In order to make the atomization environment less or anaerobic during water atomization, first, the atomization cylinder must be sealed to isolate the atomization environment from the surrounding environment. Secondly, it is necessary to remove the oxygen in the closed atomization cylinder. Finally, such an oxygen-free or low-oxygen atomization environment is maintained during the atomization process, until the atomization is over, all the alloy droplets solidify into alloy powder.


Production investment cost

The investment in equipment for water atomization and gas atomization is the same. The investment for aerosolized cylinders is relatively large, but the atomization medium working group-gas cylinders, meters and valves have a small investment; water atomization is On the contrary, the input of the atomization cylinder is smaller than that of the gasification, but the input of the high-pressure water pump and the centrifugal water pump is greater than that of the gas atomization atomization medium working group. In other parts, the investment of the two is similar, and when combined, it is almost the same.


Unit alloy powder production cost

The production cost per kilogram of alloy powder is higher in gas atomization than in water atomization. According to actual calculations, the cost of atomizing medium is required for gas atomization to make one kilogram of alloy powder. When water is atomized, the main energy consumed by the atomizing medium is the electrical energy when the water pump is running. For this reason, gas atomized alloy powders on the market are generally more expensive than water atomized alloy powders.
