Jis H4100 Standard Pdf [updated] Jun 2026

The international standard governing wrought aluminum and aluminum alloy extruded rods, bars, tubes, and profiles. Accessing the JIS H4100 Standard PDF

When reviewing the JIS H4100 standard PDF, technical professionals should focus on several core sections:

JIS H4100 covers made from aluminium and its alloys. Developed by the Japanese Industrial Standards Committee (JISC), this document outlines technical delivery conditions. It guarantees that materials manufactured under this designation meet strict structural and chemical benchmarks. Core Scope Manufacturing Method: Hot extrusion processes. jis h4100 standard pdf

The standard also specifies plane-strain fracture toughness values ranging from 22.0 to 35.0 MPa·√m for typical wrought aluminum alloys.

. It establishes rigorous requirements for the chemical composition, mechanical properties, and dimensional tolerances of extruded shapes used in various industries. Intertek Inform Scope and Recent Revisions As of early 2026, the current version is JIS H 4100:2022 and twist over specific lengths.

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.

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). T6). Whether you are an engineer

Whether you are an engineer, manufacturer, quality control professional, or procurement specialist, understanding JIS H4100 is crucial for working with Japanese aluminum extruded profiles. The standard’s alignment with ISO specifications and its relationship with other JIS standards (like JIS H4000) makes it a valuable reference within the global aluminum industry.

JIS H4100 categorizes dimensional tolerances into "Standard" and "Special" precision classes. It provides detailed reference tables for allowable deviations in: Wall thickness and cross-sectional dimensions. Straightness, flatness, and twist over specific lengths. Angular variations in custom shapes. 4. Quality Control and Testing Methods

One of the most valuable features of the JIS H 4100 standard is its detailed classification of aluminum alloys. The standard lists dozens of approved alloys, each designated with a specific JIS symbol.
