While JIS H 4100 is mandatory in Japan, it is a globally recognized quality benchmark. Other industrial nations have their own equivalent standards. The most relevant are from the system:
: Profiles featuring an entirely solid cross-section with no enclosed internal voids.
Excellent extrusion response, good strength, highly responsive to heat treatment, easy to anodize.
Whether you are an engineer, manufacturer, quality control professional, or procurement specialist, understanding JIS H4100 is crucial for working with Japanese aluminum extruded profiles. The standard’s alignment with ISO specifications and its relationship with other JIS standards (like JIS H4000) makes it a valuable reference within the global aluminum industry.
For those interested in accessing the JIS H4100 standard, a PDF version is available from the Japanese Standards Association (JSA) website or other online platforms that sell standards. The PDF version provides a detailed and authoritative source of information on the standard, including its scope, chemical composition, mechanical properties, dimensions, and testing methods.
The Japanese Industrial Standard JIS H 4100 is a cornerstone document for the aluminum industry. As the principal specification for aluminum and aluminum alloy extruded profiles, it governs a significant portion of the manufacturing, quality control, and international trade of these materials. This comprehensive article explores everything you need to know about the JIS H4100 standard, from its technical scope and common alloys to practical advice on how to obtain the official PDF document.
Manufacturers complying with JIS H4100 must subject material batches to several verification checks:
: Architectural sashes, civil engineering materials, furniture, home appliances, vehicle components, consumer products requiring complex cross-sectional shapes
For non-Japanese speakers, the JSA offers an English-translated version of JIS H4100. Note: The English version is a translation; in case of dispute, the Japanese original is authoritative.
Offers excellent corrosion resistance and high electrical conductivity, but low mechanical strength.
Heavy-duty heat sinks and structural enclosures.
Understanding JIS H 4100: The Gold Standard for Aluminum Extrusions
Furthermore, the document establishes two primary tolerance classes for dimensional accuracy:
Al-Mg-Si alloys (e.g., A6061, A6063). The most common series for structural extrusions. They offer excellent extrudability, good strength, and high corrosion resistance.
Your search for should end with an informed decision. While it can be tempting to hunt for a free copy, the risks of using an incorrect, outdated, or pirated standard far outweigh the cost savings. A legitimate PDF ensures your extruded aluminum products meet the rigorous safety, performance, and dimensional requirements expected in global trade.
The standard defines rigorous mechanical property requirements that must be verified through tensile strength tests, proof stress (yield strength) tests, elongation tests, and hardness tests conducted according to sections 7.2 and 7.3 of the standard.
