The JIS H4100 standard applies to aluminum and aluminum alloy sheets, plates, and strips used in a wide range of industries, including construction, transportation, and consumer goods. The standard classifies products into several categories based on their chemical composition, mechanical properties, and applications. The products are categorized into:
| Aspect | Official Paid PDF | Unofficial Free PDF | | :--- | :--- | :--- | | | Guaranteed current version | Often 10–20 years old | | Legality | Fully compliant | Copyright infringement | | Updates | Notified of revisions | No updates; obsolete data | | Printing | High-resolution, watermarked for security | Blurry scans, missing tables | | Audit proof | Acceptable to ISO auditors | Unacceptable; will fail audits |
Global supply chains often require cross-referencing JIS H4100 with alternative international standards. While properties are highly similar, slight variations exist in tolerance classes and testing frequencies.
is the Japanese Industrial Standard titled “Aluminum and aluminum alloy extruded shapes.”
The JIS H4100 standard plays a crucial role in ensuring the quality and reliability of aluminum alloy plates, sheets, and strips. The standard provides a common language and set of requirements for manufacturers, suppliers, and customers, facilitating communication and trade. jis h4100 standard pdf

JIS H 4100 is an indispensable tool for anyone involved in the specification, design, manufacturing, or quality control of aluminum extrusions. Its comprehensive requirements for chemical composition, mechanical properties, and dimensional tolerances ensure that materials meet high, reliable standards. The designation system provides a clear, internationally consistent language for specifying alloys and tempers.
The full list of alloys in the JIS H 4100:2006 version includes well-known grades such as , and many more. To help users understand these alloys, the standard defines them in terms of three critical categories:
: Extrusions without any enclosed hollow cavities across their uniform cross-section (e.g., flat bars, angles, channels). While properties are highly similar, slight variations exist
Established by the Japanese Industrial Standards Committee (JISC) , JIS H 4100 specifies the requirements for extruded profiles made from aluminium and its alloys. These shapes are used across a vast array of industries, from high-rise building facades to automotive components and consumer electronics. Key Specifications Covered
Architectural window frames, structural beams, automotive chassis, electronic heat sinks. 5. 7000 Series (Zinc and Magnesium Alloys) Grades: JIS A7075
The standard is officially available in both Japanese and English.
