: 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).
According to the table of contents for JIS H 4100, the primary tests include:
The JIS H4100 standard is widely recognized and adopted in various industries, including:
If you'd like to dive deeper into the technical side, let me know: g., A6061 vs A6063)? jis h4100 standard pdf
The standard classifies aluminum alloys based on their chemical composition, utilizing the international four-digit numeric system. Each series offers unique performance characteristics.
: Always verify that you are downloading the most recent revision of the standard, as technical committees periodically update tolerance tables and alloy classifications to align with modern manufacturing capabilities.
The official, up-to-date standard is available in English and Japanese through the Japanese Standards Association (JSA) Webdesk. : The standard applies to all cross-sections not
The 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
The standard has a long history, first being established in 1970. Like all JIS standards, it is systematically reviewed every five years to ensure it remains relevant and technically accurate. The most recent revision from 2022 introduced the latest updates to the document.
While these standards are highly similar, minor variations exist in chemical composition limits and tolerance tighteness. Engineers must verify specific project tolerances before substituting materials. Industrial Applications Each series offers unique performance characteristics
| Alloy | Temper | Tensile Strength (MPa) | Yield Strength (MPa) | Elongation (%) | Typical Application | | :--- | :--- | :--- | :--- | :--- | :--- | | | T6 | 265+ | 245+ | 8+ | Structural, marine, automotive | | A6063S | T5 | 150+ | 110+ | 8+ | Architectural, window frames | | A7003S | T5 | 180+ | 150+ | 10+ | Automotive, structural | | A7075S | T6 | 540+ | 480+ | 7+ | Aerospace, high-strength |
Beyond chemistry, the standard defines the expected performance of the material, including tensile strength, proof stress (yield strength), elongation, and hardness. These properties vary significantly between alloys and their tempers (e.g., T5, T6).
: It covers common alloys such as 6061 (high strength), 6063 (good extrudability), and 5083 (high corrosion resistance for marine use).
