Exotic materials are crucial in industries requiring high performance, such as aerospace, automotive, medical, and energy sectors. They present unique challenges due to their strength, heat resistance, and other properties. A&M EDM uses its expertise to effectively machine these challenging materials, where conventional methods often fail.
Why Use Exotic Materials in EDM?
Exotic materials are defined by their high strength, heat resistance, and specialised properties that make them valuable for critical applications. These materials are used extensively in demanding sectors such as aerospace, automotive, medical, and energy industries, where precision and performance are paramount.
EDM is essential for machining exotic materials due to its ability to achieve high precision without inducing mechanical stress. Traditional machining methods often struggle with these materials, while EDM processes are highly effective at maintaining accuracy and integrity.
