The JIS H 4100 standard, titled "Aluminium and aluminium alloy extruded profiles," is a critical Japanese Industrial Standard (JIS) that specifies requirements for extruded shapes used in various industries, including construction, automotive, and general engineering. Scope and Application
Purpose: It defines the chemical composition, mechanical properties, and dimensional tolerances for aluminum and aluminum alloy extruded profiles.
Coverage: The standard applies to all cross-sections not already specified in other standards like JIS H 4000 (sheets), JIS H 4040 (rods), and JIS H 4080 (tubes).
Versions: The standard has undergone several revisions, with major updates in 2006, 2015, and the most recent current version, JIS H 4100:2022. Key Specifications
Alloy Classifications: It covers common alloys such as 6061 (high strength), 6063 (good extrudability), and 5083 (high corrosion resistance for marine use).
Tolerances: Specifies precise allowances for sectional dimensions, flatness, twist, and corner radii.
Classes: Differentiates between "Ordinary Class" and "Special Class" for dimensional accuracy based on specific application needs.
Testing: Mandates specific testing procedures, including tensile tests (per JIS Z 2241), hardness tests, and analytical tests for chemical composition. Global Context
JIS H 4100 is largely aligned with international standards such as ISO 6362 and ISO 209, though it contains specific modifications noted in its annexes. In global manufacturing, it is often compared to ASTM B221 (USA) and EN 755 (Europe). Acquiring the PDF

JIS H 4100 is the Japanese Industrial Standard that specifies the requirements for extruded aluminium and aluminium alloy profiles used in various general engineering, structural, and architectural applications.
First established on May 1, 1970, and updated in its most recent revision—JIS H 4100:2022 —this standard ensures that extruded profiles meet strict criteria regarding chemical composition, mechanical properties, and dimensional tolerances. What is the JIS H 4100 Standard?
The JIS H 4100 Standard serves as the primary technical guideline for wrought aluminium products transformed through the extrusion process into uniform cross-sectional profiles. Scope and Applicability
Inclusions: Applies to all cross-sections not already covered under JIS H 4040 (rods, bars) and JIS H 4080 (tubes). For quadrangular, rectangular, or hexagonal cross-sections, it applies specifically to profiles where corner radii are defined.
Alignment with International Standards: JIS H 4100 is closely harmonized with global standards, including ISO 209 (chemical composition) and ISO 6362 (parts 1, 2, 4, and 7), ensuring seamless procurement and substitution across international supply chains. 🛠️ Key Technical Specifications of JIS H 4100
Extruded profiles manufactured under the JIS H 4100 standard are rigorously tested to ensure mechanical and dimensional compliance. The document organizes profiles into Ordinary Class and Special Class designations, which dictate the strictness of the dimensional tolerances. 1. Common Alloy Grades and Applications
