The remaining digits provide further specificity. For (pure aluminum), the last two digits represent the aluminum purity (e.g., A1070 indicates 99.70% aluminum). For 2xxx through 8xxx alloys , the second digit indicates a modification of the original alloy (with "0" representing the original), and the last two digits are a serial number assigned by the Aluminum Association or, for unique Japanese alloys, a sequential number. jis h4100 standard pdf
The JIS H4100 standard applies to:
Extruded profiles manufactured under the JIS H 4100 standard are rigorously tested to ensure mechanical and dimensional compliance. The document organizes profiles into and Special Class designations, which dictate the strictness of the dimensional tolerances. 1. Common Alloy Grades and Applications High corrosion resistance, weldability; 5083 is among the
: Extensively used for structural and architectural purposes due to their excellent extrudability and corrosion resistance. 5000 Series (e.g., 5052, 5083)
