In your own country, your national standards body (e.g., ANSI in the US, DIN in Germany, BSI in the UK) often resells JIS standards. This can be easier for local invoicing.
This table defines the allowable percentage of Silicon, Iron, Copper, Manganese, Magnesium, Chromium, Zinc, and Titanium. For example:
The PDF provides tables listing the permissible percentage ranges for elements like Silicon (Si), Iron (Fe), Copper (Cu), Manganese (Mn), Magnesium (Mg), Chromium (Cr), Zinc (Zn), and Titanium (Ti). For example, JIS H4100 specifies very tight limits for alloy 6063 to ensure corrosion resistance and formability. jis h4100 standard pdf
When you open the jis h4100 standard pdf, you’ll notice differences compared to equivalent international standards:
| Feature | JIS H4100 | ASTM B221 (USA) | EN 755 (Europe) | | :--- | :--- | :--- | :--- | | Alloy System | 4-digit (e.g., 6063) | 4-digit (same, but different tolerances) | EN AW-6063 | | Temper Designations | O, H112, T5, T6 | O, F, T4, T5, T6 | O, H111, T4, T5, T6 | | Tolerance Classes | Very strict (suitable for precision extrusions) | General | General | | Corrosion Testing | Mandatory for certain alloys | Optional | Required for specific applications | In your own country, your national standards body (e
Key Takeaway: JIS H4100 is generally more stringent on dimensional tolerances and surface quality than ASTM or EN equivalents, reflecting Japan’s high-quality manufacturing culture.
In the digital age, having access to the official PDF version of the standard is critical for several reasons: For example: The PDF provides tables listing the
No. For aluminum sheet and plate, refer to JIS H4000. For rolled coils, JIS H4160.
