Powder Metallurgy Overview
Powder metallurgy (PM) is a fascinating field that involves creating metal parts from powdered materials. This technique has gained prominence due to its ability to produce complex shapes with high precision and minimal waste. Its applications span a wide range of industries, from aerospace to automotive. In this blog, we will explore how powder metallurgy is applied across different sectors, highlighting its benefits and specific uses in various industries.
What is Powder Metallurgy?
Powder metallurgy is a manufacturing process where metal powders are compacted and sintered (heated without melting) to create solid metal parts. This process allows for the production of components with complex geometries, superior material properties, and reduced waste compared to traditional machining methods.
Key Applications of Powder Metallurgy
