The JIS H4100 standard is a critical standard for the quality control and assurance of aluminum and aluminum alloy sheets, plates, and strips. The standard provides guidelines for the classification, inspection, and testing of these products, ensuring that they meet the required quality and performance standards. The standard has significant implications for various industries, including construction, transportation, and consumer goods.
JIS stands for , the equivalent of ASTM (USA), DIN (Germany), or BS (UK). Specifically, JIS H4100 governs Aluminum and Aluminum Alloy Extruded Tubes and Bars .
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.

The standard includes visual inspection criteria for surface defects, die lines, scratches, and oxidation.
The JIS H4100 standard sets strict quality requirements for aluminum and aluminum alloy sheets, plates, and strips, including:
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 The JIS H4100 standard is a critical standard
JIS H4100:2022 (Aluminum and Aluminium Alloy Extruded Shapes) is a Japanese Industrial Standard (JIS) that specifies the requirements for extrusions produced from aluminum and its alloys.
The most current version is JIS H 4100:2022 , which replaced the 2015 edition.
Note: For international trade, it is crucial to verify if the "Special Class" or "Ordinary Class" requirements in JIS H4100 align with ASTM or EN specifications. Conclusion JIS stands for , the equivalent of ASTM
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 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:
The standard provides comprehensive tolerance classes to accommodate varying precision requirements. Each of these tolerances is defined in dedicated sections of the standard, with specific limits prescribed for each class:
