Extrusions must be free from detrimental defects. The standard regulates acceptable levels of surface imperfections, such as extrusion lines, scratches, pitting, and die marks. Comparative Equivalents
The standard applies to all cross-sections, with specific exclusions for items governed by alternative frameworks: Applies to aluminum bars, wires, and rods. JIS H 4080: Regulates specialized aluminum tubes and pipes. Extrusion Classes
JIS H4100 specifies the requirements for extruded shapes made from aluminum and aluminum alloys. Developed by the Japanese Industrial Standards Committee (JISC) and published by the Japanese Standards Association (JSA), this standard covers solid and hollow shapes used in structural, automotive, architectural, and general engineering fields. Core Focus Areas of the Standard
Precision is vital for extruded profiles to fit seamlessly into assemblies. JIS H4100 outlines explicit allowable variations for: Cross-sectional dimensions (thickness, width, height). jis h4100 standard pdf
The 2015 version has now been superseded and replaced by the 2022 edition. The 2006 version remains available for historical reference.
Harmonized extensively with global standards like ISO 209 and ISO 6362, introducing the refined terminology "extruded profiles".
Understanding the JIS H4100 Standard for Aluminum Extrusions Extrusions must be free from detrimental defects
The most common extrusion alloy. Known for excellent extrudability, medium strength, and superior corrosion resistance. Used for:
Whether you are designing extruded profiles for automotive parts, architectural frames, or electronic casings, understanding the nuances of this standard is critical. A common search among professionals is finding a reliable . But beyond simply locating the file, what does this document contain, and why is it so essential?

Information asymmetry undermines safety and innovation. When only a subset of stakeholders can consult the authoritative procedure for performance testing, the uniformity that standards are intended to ensure begins to fray. Subtle but crucial details—test fixture geometries, sampling intervals, or failure-acceptance thresholds—can be lost or miscommunicated. That increases the likelihood of inconsistent results between suppliers and customers, which in turn raises liability and safety concerns.
