Jis H4100 Standard Pdf

Offers excellent corrosion resistance and high electrical conductivity, but low mechanical strength.

The JIS H 4100 includes alloys from the 1000 to 7000 series. The 6000 series (Al-Mg-Si alloys) are the most widely used for extrusion, while the 7000 series (Al-Zn-Mg alloys) offer high strength for demanding applications. A comparison of key alloys is presented below:

The is the definitive Japanese Industrial Standard specifying the technical requirements, chemical compositions, and dimensional tolerances for extruded aluminium and aluminium alloy profiles . Maintained by the Japanese Standards Association (JSA) and coordinated by the Japanese Industrial Standards Committee, the standard governs general engineering, architectural, manufacturing, and automotive aluminum extrusions.

Straightness and twist limits along the length of the extrusion. Flatness and angularity of the profile walls. Cut-to-length tolerances. 3. Surface Quality jis h4100 standard pdf

JIS H4100 is the Japanese Industrial Standard that specifies requirements for extruded aluminum and aluminum alloy profiles (extruded shapes). The standard, officially titled “Aluminium and aluminium alloy extruded profiles” (in Japanese: アルミニウム及びアルミニウム合金の押出形材), provides detailed specifications for manufacturing, testing, and quality assurance of extruded aluminum products.

The standard categorizes aluminium alloys based on their chemical composition and heat treatment. The most common alloy series governed by JIS H4100 include: A comparison of key alloys is presented below:

Exact percentage limits for alloying elements like silicon, iron, copper, manganese, magnesium, chromium, zinc, and titanium.

JIS H4100:2022 (Aluminum and Aluminium Alloy Extruded Shapes) is a Japanese Industrial Standard (JIS) that specifies the requirements for extrusions produced from aluminum and its alloys.

A certified JIS H4100 PDF outlines precise technical boundaries that a manufacturer must fulfill. These specifications ensure that materials from different suppliers remain interchangeable and safe. Chemical Composition Flatness and angularity of the profile walls

Beyond chemistry, the standard defines the expected performance of the material, including tensile strength, proof stress (yield strength), elongation, and hardness. These properties vary significantly between alloys and their tempers (e.g., T5, T6).

: The maximum stress a material can withstand before breaking.

The JIS H 4100 standard is far more than just a technical document; it is the international benchmark for quality and precision in the world of aluminum extrusions. By providing an ironclad framework for chemical makeup, mechanical performance, and dimensional accuracy, it guarantees the safety and reliability of everything from a building's window frame to an electric vehicle's structural battery case. Its rigorous two-tier system of Ordinary and Special Grades gives engineers the flexibility to choose the exact level of precision they need. For any professional involved in specifying, manufacturing, or purchasing extruded aluminum components, a deep understanding of is not just beneficial—it is essential for ensuring product quality and success in the global marketplace.

Precision is vital for extruded profiles to fit seamlessly into assemblies. JIS H4100 outlines explicit allowable variations for: Cross-sectional dimensions (thickness, width, height).
