ECO-Almag is a high-strength, highly formable aluminum-magnesium alloy that is gaining attention as a stainless steel alternative in the semiconductorand display industries.

Why is ECO-Almag suitable for the semiconductor and display industries?

ECO-Almag is a next-generation aluminum-magnesium alloy that combines high strength, ultra-precise formability, and excellent thermal conductivity. It is gaining attention in the semiconductor and display industries as a next-generation material that meets ESG standards by reducing carbon emissions and enhancing material recyclability.
