While Part 1 of the series covers the mechanical properties and the chemical composition of the alloys, Part 2 is entirely dedicated to the geometry. It dictates exactly how much deviation is allowable in the shape and size of an extruded profile. This is crucial because extrusion is a process where hot metal is forced through a die; while it produces consistent shapes, thermal contraction and die wear mean that achieving absolute mathematical perfection is impossible. Tolerances define the acceptable limits of that imperfection.
The European Standard EN 755-2 is a widely recognized document that specifies the technical conditions for the delivery of aluminum extrusions. This standard is essential for manufacturers, suppliers, and customers in the aluminum industry, as it ensures that extrusions meet specific requirements for quality, safety, and performance. In this article, we will provide an overview of EN 755-2, its significance, and where to find a free PDF download. en 755-2 pdf free download
