EN 1669 is the European test method for the earing tendency of aluminium and aluminium alloy sheet and strip after a controlled deep-drawing operation. To match this to your program, talk with our team.
What EN 1669 Covers
It quantifies the earing (wavy edge) that results from planar anisotropy in aluminium sheet, important for deep-drawing and forming quality.
How the Test Is Run
A blank is deep drawn into a cup under defined conditions, and the height and pattern of the ears formed at the cup rim are measured.
Why It Matters
Earing behaviour governs formability and scrap in deep-drawn aluminium parts; a deep-drawing press and accurate ear measurement are used.
