Note: Values are indicative; exact figures vary by section thickness.
The most popular extrusion series (e.g., 6061, 6063). They balance high strength, excellent extrudability, and good surface finishing capabilities.
These chemical limits, verified by standardized testing methods, are the foundation for achieving the mechanical properties required by the standard.
Handrails, modular profiles, scaffolding, and storage racks.
The standard uses a four-digit alloy designation system (e.g., 6061, 7075, 6063). It also defines temper designations:
Pure aluminium and wrought aluminium alloys.
Offers excellent corrosion resistance and high electrical conductivity, but low mechanical strength.
When reviewing the PDF document, pay close attention to the . The core text defines the testing methodologies, while the appended tables list the exact numbers for chemical thresholds, mechanical limits, and tolerance classes based on the thickness of the profile walls. Always verify the revision year on the cover page to ensure compliance with modern engineering requirements.
user wants a long article about the keyword "jis h4100 standard pdf". This likely refers to the Japanese Industrial Standard JIS H 4100, which covers aluminum alloys for extrusion profiles. The article should be detailed, explaining the standard, its different alloys, applications, and how to obtain the PDF. To write a comprehensive article, I need to gather a variety of information. I will search for the standard itself, explanations of its content, technical details, applications, differences with other standards like AISI or ASTM, and free online viewing or purchasing options. search results provide a variety of sources. I will open several of them to gather detailed information for the article. gathered information provides a solid foundation. I will structure the article with an introduction, sections on scope and revisions, key alloys and properties, applications, quality control, obtaining the PDF, and a conclusion. I'll cite sources like the JSA page, Normsplash, Riken Keikinzoku, and others. is a detailed article covering the JIS H4100 standard, its applications, specifications, and how to obtain the PDF document.
Defines the stress at which permanent deformation begins. Elongation (%): Measures the material's ductility.

," is a cornerstone of Japanese industrial manufacturing, ensuring the quality and consistency of extruded aluminum shapes. First established on May 1, 1970
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.
The JIS H4100 standard applies to aluminum alloy sheets and plates used in various applications, including:
: Specifies requirements for extruded aluminium and aluminium alloy profiles (also called "shapes"). Applicability
When sourcing, designing, or manufacturing aluminum components that align with Japanese engineering requirements, obtaining the is critical to maintaining regulatory and quality compliance. Document History and Current Edition
