: It defines the chemical composition, mechanical properties, and dimensional tolerances for aluminum and aluminum alloy extruded profiles.
The of the four-digit code identifies the alloy series by its principal alloying element, which dictates its primary characteristics. The table below outlines the meaning of the first digit: jis h4100 standard pdf
Testing Methods: The document outlines how manufacturers should perform tensile tests and visual inspections to verify compliance. Why the JIS H4100 Standard Matters Why the JIS H4100 Standard Matters A critical
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 Flatness of flat surfaces
The stress level at which a material begins to deform permanently.
One of the most valuable features of the JIS H 4100 standard is its detailed classification of aluminum alloys. The standard lists dozens of approved alloys, each designated with a specific JIS symbol.
The JIS H4100 standard also specifies the mechanical properties of aluminum alloy plates, sheets, and strips, including:
