Gas Atomization (Gas Atomization Process) is one of the most common methods for manufacturing metal powders, which is a process for manufacturing fine powders by ejecting gas into molten metal. During the gas automization process, metal powders are obtained when the high pressure gas jets from the nozzle gives the strong impact energy to molten metal droplets during their fall through the orifice. The changes of the factors such as gas type and pressure, internal diameter of orifice and nozzle type have an effect on the major characteristics such as powder properties, shapes and particle size distribution.
⦁ Properties of HANA AMT’s metal powders that manufactured by gas atomization
- Globular powders with homogeneous particle size distribution
- Easy to be synthesized and mixed with other element powders
- Excellent liquidity of powders
- High density of powders
- Efficient control of powder oxygen density
- Possible to manufacture powders with irregular shapes
The magnesium metal-powder which is produced in HANAamt reveals the following unique characteristics.
⦁ Spherical powder is produced which is then screened and blended to customer specifications.
⦁ Atomized powder exhibits excellent Fluidity and is easy to mix with other materials and still retain good flow characteristics and low viscosities.
⦁ It exhibits higher packing density.
⦁ It has superior stability.
USE Fine and atomized powders are widely used by the military industry in a range of flare and ordnance applications, notably decoy flares and illumination flares. Decoy flares made from magnesium burn white hot and the intense heat of the pyrotechnic candle consumes the flare housing. Such flares are designed to defeat a missile's infrared tracking capability, thus making the use of magnesium instrumental in the protection of military helicopters and aircraft. Ground illumination flares are designed to descend by parachute and illuminate ground terrain and targets.
