Despite this consolidation, original designations such as and AlBC3 continue to be standard terminology in engineering documentation worldwide. Core Alloy Grades and Chemical Composition
When utilizing the technical sheets found inside a , foundational properties dictate how the cast components behave under load or within volatile chemical environments. Chemical Composition Limits (%)
| Grade Symbol | Old Symbol | Description | Typical Applications | | --- | --- | --- | --- | | | BsC1 | Tin bronze (not strictly brass, but often included in older references). Low lead. | General valves, low-pressure fittings | | CAC202 | BsC2 | Leaded brass with excellent machinability. | Valve stems, high-speed machining components | | CAC203 | BsC3 | High-strength brass with added manganese and iron. | High-pressure valves, pump parts | | CAC204 | BsC4 | Aluminum bronze for corrosion resistance. | Marine fittings, seawater valves |
These alloys combine copper and zinc with reinforcing elements like aluminum, iron, and manganese. They offer exceptional mechanical strength, making them ideal for structural parts, propeller blades, and heavy machinery components. 3. Aluminum Bronze Castings (AIBC) jis h 5114 pdf
Major document aggregators like IHS Markit, Techstreet, or SAI Global offer licensed PDF downloads of JIS standards translated into English.
This is the standard most users likely need. There are robust legal pathways to download this PDF.
The JSA does not offer free full-text previews. However, you can often see the cover, scope, and table of contents on their website without purchasing. Low lead
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.
Alloys formerly governed by JIS H 5114 are chosen for their excellent (especially in seawater), high strength, and wear resistance. They are typically used in: Marine propellers and underwater fasteners. Heavy-duty pump and valve parts. Automotive bushings and bearings. PDF & Access
The English interface allows international buyers to purchase and instantly download a watermarked PDF. This is the most reliable source for manufacturing companies. | High-pressure valves, pump parts | | CAC204
If you are specifically looking for the content within the original H 5114 standard, it covers several classes of aluminium bronze (e.g., AlBC1, AlBC2, AlBC3, AlBC4) designed for high strength and corrosion resistance. Common Applications Marine propellers and sleeves. Bearings, bushes, and valve seats. Impellers, bolts, and nuts. Machine parts for the chemical industry. Quality Requirements
: Used for general purposes with good corrosion resistance. AlBC2 : Higher strength, suitable for gears and bushings.
