What is Powder Metallurgy?

Powder Metallurgy

Powder metallurgy (PM) is one of the most interesting and innovative manufacturing technologies to arise since the turn of the 20th century, though its beginnings were as trying as they were auspicious. Despite its relatively recent entrance into the production sector of the modern economy, PM has been around for millennia in some form or other. Powder metallurgy (PM)…

Powder Metallurgy

Powder metallurgy is a metal-forming process of ferrous-powdered materials performed by pressing and sintering metal powder compacts near to net shape of the final component. It allows very complex geometries and intricate features. The process has existed for more than 100 years. It is now widely acknowledged as a superior way of producing high-quality sintered, structural components for a…

WHEN TO USE POWDER METALLURGY (PM)?

When to use PM is a commonly asked question.  As you would expect there is no single answer, but here are some general guidelines. To make a PM part requires tooling.  The cost of the tooling depends on the size and complexity of the part, but can range from $4,000.00 to $20,000.00.  Production quantities generally must be high enough…

Leave lubrication to the parts themselves

Improper lubrication practices are a good way to ruin a product, machine or process. Many manufacturers realize the dangers of under-lubrication – increased friction and heat, and ultimately, a ruined bearing or joint. But it isn’t just a lack of lubrication that can limit an item’s effectiveness and lead to a premature death – too much grease or the…

soft magnetic

In recent decades, trends in automotive and other industries have spiked demand for new magnetic materials. As a result, in the mid-1990s the very first components made from soft magnetic composite were born. And the trend of using these soft magnetic composites (SMCs) only continues to grow. Those first SMC parts were ignition cores, used extensively in most GM vehicles. They…

What is the purpose of copper infiltration into a PM component, and how is it accomplished?

Components are copper infiltrated for a number of reasons. Some basic desired results are improvements to tensile strength, hardness, impact properties, and ductility. Copper-infiltrated components will also have a higher density.  Other reasons customers may elect copper infiltration are for wear improvement or to block air/gas flow through an otherwise porous component at temperatures that a resin may not be practical.  Sometimes copper infiltration is used…
