Sharp corners are rarely feasible or desirable in extrusion. The standard sets out default maximum and minimum radii unless otherwise specified in a drawing, ensuring that parts fit together without stress concentrations.

If you are manufacturing a window frame, an automotive component, or a structural element for aerospace, you cannot simply request "a 50mm bar." You must specify a 50mm bar with specific tolerances.

That said, I can offer a covering:

The point at which the material begins to deform plastically. Elongation (

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.

However, downloading these documents from unauthorized third-party repositories, file-sharing sites, or "shadow libraries" carries significant risks that professionals cannot afford to ignore. en 755-2 pdf free download

Students and professionals can often access full standards for free through university libraries or internal company subscriptions to databases like IHS Markit or BSI.

The standard is a critical European document that specifies the mechanical property limits for extruded aluminum and aluminum alloy rods, bars, tubes, and profiles. While the full, official document is generally not available for legal "free download" due to copyright, many users seek it to verify guaranteed values for tensile strength, yield strength, and elongation before purchasing materials. Understanding the EN 755-2 Standard

One of the most common defects in extrusion is bowing (curvature along the length) or twisting. EN 755-2 provides tables detailing the maximum allowable deviation per meter of length. For example, a profile with a wider wall thickness may be allowed a different tolerance range than a thin-walled complex shape.
