Production of metal powders
This technology has been known to people since ancient times. With its help, people of the past decorated jewelry, everyday objects.
So what exactly is powder metallurgy? This is a rather complex and time-consuming process for the production of powders and mixtures of various metals, which are used in mechanical processing and the creation of more complex products.
It includes four main stages:
Compaction (pressing, briquetting)
With regard to the mass production of metal products, this technology is more profitable in economic terms than the piecemechanical processing of goods. Moreover, it makes it possible to obtain products of high accuracy, due to the possibility of forming the physicochemical structures of products with special characteristics.
Methods for obtaining metal powders
Grinding on specialized equipment (vibratory and ball mills)
Spraying alloys and melts (metals in liquid form) by placing them in inert gases or exposure to air
Recovery of ores or scales
Removal of metals from solutions by electrolytic deposition
By applying an electric current to a metal placed in a vacuum.
The methods are based on the type of raw materials, their quantity and quality. Powder metal prices are formed in the aggregate of all factors that are involved in production.

As mentioned above, more complex hardware is created from this type of product, mechanical processing is carried out by spraying on the product. Moreover, powders are used to create all kinds of alloys, for example, aluminum-nickel, which must have very precise proportions of the components involved. These alloys are called precision alloys.
Thanks to this technology, it is possible to alloy metals and alloys in such a way that they will be any necessary qualities that were previously missing from them.
