Jis H 5114 Pdf [verified] Today
JIS H 5114 outlines the standardized requirements for produced in Japan. This standard ensures that copper alloys—including bronzes, brasses, and specialized high-strength copper variants—meet rigid benchmarks for chemical composition, mechanical performance, and structural integrity.
The original JIS H 5114 standard was introduced to standardise heavy-duty, copper-based casting alloys. Over time, the Japanese Industrial Standards Committee consolidated its metallurgical frameworks. Withdrawn / Superseded .
The core of JIS H 5114 was its classification system for aluminum bronze castings into different grades, known as the "AlBC" series. These grades were designated based on their chemical composition and expected mechanical properties. The standard defined several key grades, including:
| | Typical Percentage | Role | | :--- | :--- | :--- | | Copper (Cu) | Balance (~96-98%) | Base metal | | Beryllium (Be) | 1.8 – 2.0% | Primary hardening agent | | Cobalt (Co) + Nickel (Ni) | 0.2 – 0.6% | Grain refiner and precipitation hardener | | Other Elements (Fe, Pb) | < 0.2% | Impurities and trace elements | jis h 5114 pdf
The unified JSA Group Standards Catalog maintains the current compliance benchmarks for these specific alloys under the consolidated standard numbers. Material Classification & Chemical Composition
The standard, established by the Japanese Industrial Standards Committee (JISC) , was the primary specification for Aluminum Bronze Castings in Japan. While it has largely been superseded by newer consolidated standards, it remains a critical reference for engineers, manufacturers, and quality control specialists handling legacy equipment or specific industrial applications requiring aluminum bronze. 1.
