Jis H4100 - Standard Pdf

The Japanese Industrial Standard (JIS) H4100 is a widely recognized standard for aluminum alloy sheets and plates. This standard specifies the requirements for the quality, testing, and inspection of aluminum alloy sheets and plates used in various industries, including construction, transportation, and manufacturing. In this post, we will provide an overview of the JIS H4100 standard, its significance, and the benefits of using it.

| JIS Alloy | Temper | Tensile Strength (MPa) | Yield Strength (MPa) | Elongation (%) | |---|---|---|---|---| | A1200S | O (Annealed) | 78.0 min | 20.0 min | — | | A5052S | O (Annealed) | — | — | 20.0 min | | A6061S | T6 (Heat-treated) | 265 min | 245 min | ≥ 8 (varies by thickness) | | A7N01S | O (Annealed) | 245.0 | — | 12.0 |

A critical point of the standard is that it applies to "all cross-sections not specified in JIS H 4000, JIS H 4040 and JIS H 4080". This means that while other JIS standards cover specific forms like aluminum sheets, plates, and bars, JIS H 4100 is the default specification for all other custom extruded profiles.

The JIS H4100 standard provides guidelines for the dimensions and tolerances of aluminum alloy plates, sheets, and strips, including: The Japanese Industrial Standard (JIS) H4100 is a

: The amount of stretch the material can endure before fracture, indicating ductility. Dimensional Tolerances

: Covers various alloys including 1070 (high conductivity), 5052 (intermediate strength/corrosion resistance), and 6063 (common for structural extrusions). Specified Properties :

Limits on bending over the length of the product. : Structural frames, bumper beams, subframes, and heat sinks

If you need help analyzing specific sections of this document, please let me know:

A critical feature of JIS H 4100 is its detailed system for dimensional tolerances, which is essential for ensuring the extruded profiles meet the requirements of precision applications. The standard is structured to maintain high quality across several key aspects of the profiles.

The latest major revision, , technically revised and replaced the 2015 version to align more closely with modern international standards like ISO 6362. Key Specifications & Alloy Grades

The official document ensures accuracy in chemical compositions, temper classifications, and tolerances, which is vital for quality control and auditing. 7. Comparison with International Standards

A critical section of the JIS H4100 PDF covers geometric accuracy. It defines acceptable limits for: Cross-sectional dimensions (thickness, width, height). Straightness and twist tolerances over specific lengths. Flatness of flat surfaces. Angular tolerances for corners and bends. 4. International Equivalents to JIS H4100
