The Precision of Powder Metallurgy

The Precision of Powder Metallurgy

Medical implants are on the rise. Over 4.7 million Americans have undergone complete knee replacements and 2.5 million have undergone total hip arthroscopy. This is a global trend, and the precision of powder metallurgy (PM) plays a role in improving quality of life through its ability to meet or exceed expectations in regards to size, complexity, material properties, volume, reliability, and bio-compatibility.

Review the medical case studies below to learn how and why PM has earned its reputation as a precise and reliable metal-forming technology.
