Aluminiums bronzes formulated under JIS H 5114 are selected specifically for environments where standard brass or tin-bronze alternatives fail under load. The mechanical testing metrics defined within the specification ensure optimal performance bounds:
The standard covers aluminum bronze castings manufactured via various methods, including sand molding, metal molding, centrifugal casting, and continuous casting. It categorizes materials into distinct classes based on their chemical makeup and intended performance: AlBC1 (Class 1): Known for good ductility and standard corrosion resistance. AlBC2 (Class 2): Often used for bearings, bushes, and valve seats. AlBC3 (Class 3):
Incorporates 2.5% to 5.0% Iron and 1.0% to 3.0% Nickel. This grade provides improved mechanical strength over AlBC1 and is commonly selected for small marine components, bushings, and high-wear fasteners.
Based on technical documentation, the standard covers several critical inspection and material criteria: : jis h 5114 pdf

is a Japanese Industrial Standard that historically specified the requirements for aluminium bronze castings, often referred to as "castings" in engineering contexts. Aluminium bronzes are a family of copper-based alloys known for their exceptional strength, corrosion resistance, and wear resistance, making them ideal for heavy-duty marine, industrial, and chemical applications.

Sampling rules are strictly defined to ensure the composition of the castings meets the required alloy specifications. Applications of JIS H 5114 Castings
If you are working with a printout from 1998, you risk producing non-compliant parts.
JIS H 5114 classifies aluminum bronze into four primary classes (often designated as AlBC2 (Class 2): Often used for bearings, bushes,
For casual reference, some public libraries in Japan have JIS handbooks. However, for professional use, always purchase the official PDF.
For modern engineering or new manufacturing setups, purchase the current unified document: JIS H 5120 from the GlobalSpec Standards Library.
