The JIS H4100 standard was first established in 1961 by the Japanese Standards Association (JSA) to standardize the quality and testing methods of aluminum and aluminum alloy sheets, plates, and strips. Since then, the standard has undergone several revisions to reflect advances in technology and changes in market demands. The current version of the standard, JIS H4100:2019, was published in 2019.
Ultra-high-strength alloys used primarily in aerospace and high-stress structural automotive components. 3. Key Technical Specifications Chemical Composition jis h4100 standard pdf
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 The JIS H4100 standard was first established in
The scope of JIS H 4100 is precisely defined. It applies to whose cross-sectional shapes are not specified by other related standards like JIS H 4000 or JIS H 4080. or a supplier exporting to Japan
It is the definitive standard for extruded shape tolerances, mechanical properties, and chemical compositions for aluminum products made via extrusion processes. If a manufacturer in Japan, or a supplier exporting to Japan, produces an aluminum square tube, flat bar, or custom profile, it almost certainly complies with JIS H4100.
