How to Read a JIS H 5114 Specification on a Drawing

When you open the PDF, you will typically see a table like this in a mechanical drawing:

Material: JIS H 5114 CAC202

This means:

JIS H 5114 = Standard for brass castings (valves, flanges, fittings)

CAC202 = Grade symbol (leaded brass, high machinability)

If you see additional numbers (e.g., JIS H 5114:1996), that indicates the revision year. Always match the revision to the drawing's issue date.

Summary

JIS H 5114 is the definitive standard for copper alloy castings in Japan. It ensures that materials used in machinery and marine applications meet strict chemical and mechanical thresholds. The CAC* designation is the key identifier to look for on mill certificates.

How to use the standard effectively

Identify the exact clause(s) relevant to your design or procurement requirements.

Cross-check referenced standards and normative documents listed in the standard.

Use the specified dimensions and tolerances when creating drawings or ordering parts.

Follow the prescribed testing procedures for quality verification.

Keep a dated copy in project documentation; note the edition/version used.

JIS H 5114 was the Japanese Industrial Standard for Aluminium Bronze Castings. It provided technical requirements for copper-aluminum alloys used in high-stress applications like marine hardware, valve components, and gears. Current Status

JIS H 5114 is now inactive. In 2006, it was consolidated into JIS H 5120 (Copper and Copper Alloy Castings), which unified several separate casting standards. Core Technical Content (Historical)

The standard specified the following criteria for aluminium bronze castings:

Chemical Composition: Defined the weight percentages for copper, aluminum, iron, and nickel. Common grades included:

AlBC1: Used for general purposes with good corrosion resistance. AlBC2: Higher strength, suitable for gears and bushings.

AlBC3: High-strength variant often used for propellers and heavy-duty machinery.

Mechanical Properties: Established minimum requirements for tensile strength, elongation, and hardness to ensure structural integrity.

Manufacturing Control: Outlined requirements for test piece preparation, taking positions for hardness tests, and necessary markings (e.g., manufacturer's name, manufacture date, and class symbol).

Inspection Standards: Detailed the sampling methods and test procedures necessary to verify that the castings met chemical and physical requirements before shipment. Applications

Alloys formerly governed by JIS H 5114 are chosen for their excellent corrosion resistance (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 jis h 5114 pdf

JIS H 5120:2016 Copper and copper alloy castings - Intertek Inform

JIS H 5114 is the historical Japanese Industrial Standard Aluminum Bronze Castings

. It provides the technical framework for the chemical composition, mechanical properties, and manufacturing methods of these high-strength, corrosion-resistant alloys. 🏗️ Status and Modern Equivalence In 2016, JIS H 5114 was officially superseded and integrated into two more comprehensive standards: JIS H 5120 : Now covers general copper and copper alloy castings. JIS H 5121 : Dedicated to copper alloy continuous castings.

If you are looking for current procurement specifications, you should reference JIS H 5120 for sand or metal mold casting and JIS H 5121 for continuous casting. 🧪 Material Grades and Composition

JIS H 5114 classifies aluminum bronze into four primary classes (often designated as

grades). These alloys are primarily copper-based, with aluminum as the chief alloying element to improve strength and hardness. Major Elements (Typical %) Primary Characteristics Cu, Al (8.0-10.0), Fe (1.0-4.0) Standard grade with good balance of strength. Cu, Al (8.0-10.5), Fe (2.5-5.0), Ni (1.0-3.0) Improved corrosion and wear resistance. Cu, Al (8.5-10.5), Fe (3.0-6.0), Ni (3.0-6.0) High strength; resistant to cavitation/erosion. Cu, Al (6.0-9.0), Fe, Ni, Mn Specialized high-manganese aluminum bronze. ⚙️ Mechanical Properties JIS H 5114 was the Japanese Industrial Standard

Aluminum bronzes are valued for having mechanical properties comparable to low-alloy steels while maintaining the corrosion resistance of copper. Tensile Strength : Ranges from 490 MPa to over 590 MPa depending on the class. : Typically measured via Brinell (HBW) , ranging from 120 to 150+ Elongation : Generally 15% to 20% , ensuring the material is tough rather than brittle. Corrosion Resistance

: Excellent against seawater, making it a staple in marine engineering. 🚢 Industrial Applications

Because of its superior resistance to corrosion and wear, JIS H 5114 (AlBC) materials are found in demanding environments: Marine Engineering : Propellers, pump impellers, and valve seats. Valves & Fittings : Marine bronze globe valves and check valves. Heavy Machinery : Bushings, gears, and high-load bearings. Chemical Industry : Parts requiring resistance to acidic or erosive fluids. 📝 Testing and Quality Control

The PDF version of the original JIS H 5114 standard outlines strict testing protocols: Tension Test JIS Z 2241

using specialized "Type F" specimens cast alongside the product. Hardness Test : Executed per JIS Z 2243 Chemical Analysis : Governed by JIS H 1252 JIS H 0321 for sampling procedures. Inspection
