Fragmented, unofficial reproductions proliferate. In response to access friction, professionals may rely on colleague-shared PDFs, unofficial summaries, or outdated local copies. This increases legal ambiguity and the risk that critical updates—revisions correcting measurement methods or tightening safety margins—are missed.
A full JIS aluminum material designation also includes:
Specifies various extruded shapes, including those with hollow or solid cross-sections. Alloys Covered: Includes common series such as (pure aluminum), (magnesium alloyed), and (magnesium and silicon alloyed). Tolerances:
The classification system used by JIS H 4100 is fundamental for selecting the correct alloy for an engineering or manufacturing application. It is based on the four-digit designation system, which is generally aligned with the AA (Aluminum Association of the USA) system but includes unique Japanese designations (indicated by the letter “N”). jis h4100 standard pdf
Before making a purchase, it is always recommended to first check the to confirm the latest edition, which is currently JIS H 4100:2022 .
: It is closely aligned with international standards such as (chemical composition) and
JIS H 4100 - Aluminium and aluminium alloy extruded profiles Fragmented, unofficial reproductions proliferate
The standard classifies aluminum alloys based on their chemical composition, utilizing the international four-digit numeric system. Each series offers unique performance characteristics.
This is the most referenced section. The document specifies minimum values for:
: 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. A full JIS aluminum material designation also includes:
