Jis H4100 Standard Pdf [2024]

Introduction

The Japanese Industrial Standard (JIS) H4100 is a widely recognized standard for the classification, inspection, and testing of aluminum and aluminum alloy sheets, plates, and strips. The standard provides guidelines for the quality, dimensions, and performance requirements of these products. In this paper, we will provide an overview of the JIS H4100 standard, its significance, and its applications.

History and Development of JIS H4100

The JIS H4100 standard was first established in 1961 by the Japanese Standards Association (JSA) to standardize the quality and testing methods of aluminum and aluminum alloy sheets, plates, and strips. Since then, the standard has undergone several revisions to reflect advances in technology and changes in market demands. The current version of the standard, JIS H4100:2019, was published in 2019.

Scope and Classification

The JIS H4100 standard applies to aluminum and aluminum alloy sheets, plates, and strips used in a wide range of industries, including construction, transportation, and consumer goods. The standard classifies products into several categories based on their chemical composition, mechanical properties, and applications. The products are categorized into:

  1. Pure aluminum sheets, plates, and strips ( Grades A1050, A1070, A1080, etc.)
  2. Aluminum alloy sheets, plates, and strips ( Grades A2024, A5083, A6061, etc.)

Quality Requirements

The JIS H4100 standard sets strict quality requirements for aluminum and aluminum alloy sheets, plates, and strips, including:

  1. Chemical Composition: The standard specifies the chemical composition requirements for each grade of aluminum and aluminum alloy products.
  2. Mechanical Properties: The standard requires products to meet specific mechanical properties, such as tensile strength, yield strength, and elongation.
  3. Surface Quality: The standard specifies the surface quality requirements, including the presence of defects, scratches, and other imperfections.
  4. Dimensional Tolerances: The standard sets dimensional tolerances for products, including thickness, width, and length.

Inspection and Testing

The JIS H4100 standard requires products to undergo various inspections and tests to ensure compliance with the standard. These include:

  1. Visual Inspection: A visual inspection is performed to check for surface defects and imperfections.
  2. Chemical Analysis: Chemical analysis is conducted to verify the chemical composition of products.
  3. Mechanical Testing: Mechanical tests, such as tensile testing and hardness testing, are performed to verify the mechanical properties of products.
  4. Dimensional Measurements: Dimensional measurements are taken to verify the thickness, width, and length of products.

Applications and Significance

The JIS H4100 standard has significant implications for various industries, including:

  1. Construction: Aluminum and aluminum alloy products are widely used in construction for roofing, cladding, and structural applications.
  2. Transportation: Aluminum and aluminum alloy products are used in the manufacture of vehicles, including automobiles, aircraft, and ships.
  3. Consumer Goods: Aluminum and aluminum alloy products are used in the manufacture of various consumer goods, including packaging materials, kitchen utensils, and appliances.

Conclusion

The JIS H4100 standard is a critical standard for the quality control and assurance of aluminum and aluminum alloy sheets, plates, and strips. The standard provides guidelines for the classification, inspection, and testing of these products, ensuring that they meet the required quality and performance standards. The standard has significant implications for various industries, including construction, transportation, and consumer goods.

4. Dimensional Tolerances

Unlike general standards, JIS H4100 includes precise tables for permissible deviations on wall thickness, width, height, straightness, and twist of extruded profiles. This is crucial for die design and extrusion press setup. jis h4100 standard pdf

3. Mechanical Properties

This is the most referenced section. The document specifies minimum values for:

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.

2. Chemical Composition Limits

The PDF provides tables listing the permissible percentage ranges for elements like Silicon (Si), Iron (Fe), Copper (Cu), Manganese (Mn), Magnesium (Mg), Chromium (Cr), Zinc (Zn), and Titanium (Ti). For example, JIS H4100 specifies very tight limits for alloy 6063 to ensure corrosion resistance and formability.

What is JIS H4100?

JIS H4100 is the Japanese Industrial Standard titled “Aluminum and aluminum alloy extruded shapes.”

It defines the chemical composition, mechanical properties, and dimensional tolerances for extruded aluminum products. While many global standards exist (such as ASTM B221 in the US or EN 755 in Europe), JIS H4100 remains the primary reference point for manufacturers in Japan and is widely recognized in international supply chains, particularly in the electronics, automotive, and construction industries.

What is the JIS H4100 Standard?

JIS stands for Japanese Industrial Standards, the equivalent of ASTM (USA), DIN (Germany), or BS (UK). Specifically, JIS H4100 governs Aluminum and Aluminum Alloy Extruded Tubes and Bars. Introduction The Japanese Industrial Standard (JIS) H4100 is

It is the definitive standard for extruded shape tolerances, mechanical properties, and chemical compositions for aluminum products made via extrusion processes. If a manufacturer in Japan, or a supplier exporting to Japan, produces an aluminum square tube, flat bar, or custom profile, it almost certainly complies with JIS H4100.
