Powder Metal

About Powder Metal

The powder metal industry is complex. Here is a brief introduction to some of the basics.

Why use metal powders?

Traditionally, metal is formed and supplied as bar stock or sheets. These raw materials serve a purpose in specific manufacturing processes, such as when metal sheets are used for stamping, but they are not nearly as versatile as powder metal. Most metallic elements can be processed into metal powders (with a consistency similar to flour), and this opens up unique and far-reaching uses for metals in manufacturing and commerce.

Metal powders are utilized in a wide variety of applications, such as chemical, mechanical, and magnetic products, to name just a few, and the number of uses continues to expand. But creating and processing metal powders can be challenging, especially as more processes and applications are discovered. PMT stays on top of new applications, enabling its clients to capitalize on these new opportunities as they arise.

Manufacturing method and morphology are critical.

In simple terms, there are about 10 methods used to create metal powders. Each creates a powder with a particular morphology (size, shape, and chemistry). A powder’s specific morphology dictates the applications and processes for which it is viable. PMT’s expertise helps its clients navigate through this complex landscape.

Methods used to produce metal powders include atomization (a physical process), reduction (chemical), and electrolysis (electrical), among others. Metal powder particle sizes range from smaller than the particles in cigarette smoke to the size of sand on a beach.

Generally speaking, powder shapes fall into three categories: one-dimensional, two-dimensional, and three-dimensional. The shape of the powder particle affects the applications that are appropriate. For example, flake-shaped metal powers are viable as additives in cosmetics and industrial inks, while spherical particles are optimal for selective laser melting (SLM), a form of additive manufacturing. Sometimes different powder shapes are mixed to create a specific attribute or to save money.

How can metal powders be used?

Metal powders can be utilized in two ways, in systems and in processes. In a system, they are used without additional processing, such as for fuel additives, catalysts, and cosmetic pigments. In a process, the powders undergo additional processing that influences them in some way, as in additive manufacturing, die compaction, or sintered porous metal filtration.

PMT has identified more than 150 systems and processes that use metal powders, with applications in a diverse set of industries from aerospace to consumer electronics. The list of applications continues to expand as companies innovate, developing new products and applications that drive powder metal technology to previously unimagined heights.

Global powder metal sales continue to grow.

Revolutionary powder technology, new systems and processes, and manufacturing equipment improvements have had a positive effect on the global commercial landscape for powder metals. On a global basis, more tonnes of powder are shipped than ever before. PMT tracks industrial trends and competitive technologies in this expanding industry, and makes it a priority to have timely, accurate data and trend information to help its clients make the best business decisions.
