It is the definitive standard for extruded shape tolerances, mechanical properties, and chemical compositions for aluminum products made via extrusion processes. If a manufacturer in Japan, or a supplier exporting to Japan, produces an aluminum square tube, flat bar, or custom profile, it almost certainly complies with JIS H4100.

Understanding JIS H 4100: The Gold Standard for Aluminum Extrusions It is the definitive standard for extruded shape
The PDF provides tables listing the permissible percentage ranges for elements like Silicon (Si), Iron (Fe), Copper (Cu), Manganese (Mn), Magnesium (Mg), Chromium (Cr), Zinc (Zn), and Titanium (Ti). For example, JIS H4100 specifies very tight limits for alloy 6063 to ensure corrosion resistance and formability. These tables cover: Understanding JIS H 4100: The
JIS H4100 serves as a definitive guide for the quality of extruded aluminum. Whether you are specifying a high-strength structural beam or a precision tube for a heat exchanger, this standard provides the framework to ensure safety, quality
