Jis H4100 Standard Pdf -

The JIS H4100 standard also specifies the mechanical properties of aluminum and aluminum alloy products, including:

For professionals in engineering, manufacturing, construction, and procurement, understanding this standard is essential to ensure product reliability and conformity. This article provides an in-depth overview of the , including its scope, alloy classifications, mechanical properties, and applications. 1. What is JIS H4100?

: Imposes strict tolerance limitations for precision-crafted mechanisms, tightly fitting modular assemblies, and high-performance automotive systems. Common Alloy Specifications & Applications

: Structural cross-sections that encompass one or more fully enclosed hollow cavities.

Non-heat-treated alloys recognized for high corrosion resistance and weldability, often utilized in marine, vehicle, and welded construction applications. jis h4100 standard pdf

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.

On January 1, 1991, the standard officially replaced traditional measurement units with the International System of Units (SI) Recent Revision (2022): The current active edition is JIS H 4100:2022 , which superseded the 2015 version on December 20, 2022. What the PDF Contains

JIS H4100 stands as a fundamental standard for the aluminum extrusion industry, providing comprehensive specifications that ensure product quality, dimensional accuracy, and reliable mechanical properties. From commercially pure aluminum (1000 series) to high-strength aerospace alloys (7000 series), JIS H4100 covers a wide range of materials essential for countless applications.

The JIS H4100 standard is an important specification for aluminum and aluminum alloy products in Japan and internationally. The standard ensures that products meet certain quality and performance requirements, and compliance is essential for manufacturers, suppliers, and users of these products. The JIS H4100 standard also specifies the mechanical

: General machinery parts, structural materials, vehicles, construction, welded structures. It is weldable and brazable with good surface finishing capabilities

JIS H 4100 is a technical standard established by the Japanese Standards Association (JSA) under the authority of the Japanese Industrial Standards Committee (JISC). Its full title is “Aluminium and aluminium alloy extruded profiles”. In simple terms, it defines the rules for producing and testing aluminum shapes that are created through an extrusion process, where a heated aluminum billet is forced through a die to create a long, shaped profile.

For instance, a 6061-T6 extruded bar under JIS H4100 must meet a minimum tensile strength of 265 MPa, compared to 310 MPa for the stronger 7075-T6 alloy.

JIS H4100 covers a comprehensive range of aluminum alloys, categorized by their primary alloying elements and heat treatment capabilities. Here are the major alloy groups and their representative grades: What is JIS H4100

This alignment with ISO standards ensures that products manufactured under JIS H 4100 are widely accepted in the global marketplace, often comparable to products made under ASTM or EN specifications.

Typical mechanical properties for various JIS H4100 grades include:

| 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 |
