The keyword JIS H 5114 refers to a prominent Japanese Industrial Standard for Aluminium Bronze Castings. This standard was historically essential for engineers and manufacturers requiring high-strength, corrosion-resistant copper-based materials. However, it is important to note that JIS H 5114 has been officially withdrawn and superseded by newer, consolidated standards like JIS H 5120 (Copper and Copper Alloy Castings) and JIS H 5121 (Copper Alloy Continuous Castings).
Despite its inactive status, many legacy technical drawings and PDF specifications still reference JIS H 5114, particularly in marine and heavy industrial sectors. Overview of JIS H 5114
JIS H 5114 specifies the requirements for aluminium bronze castings manufactured through various methods, including sand mould casting, metal mould casting, centrifugal casting, and continuous casting. These alloys are prized for their exceptional mechanical properties and resistance to erosion and abrasion. Common Grades and Classifications
The standard classifies materials into several grades based on their chemical composition and intended use. The primary grades often found in PDF data sheets include:
AlBC1 (Class 1): Known for good pressure tightness and corrosion resistance.
AlBC2 (Class 2): A widely used grade for general machine parts and marine components.
AlBC3 (Class 3): Specifically designed for high-strength applications that require superior resistance to abrasion and corrosion.
AlBC4 (Class 4): Often used for heavy-duty marine propellers and chemical industry machine parts. Technical Specifications & Properties
According to technical summaries found on platforms like GlobalSpec and Scribd, the standard details rigorous quality and testing requirements:
Mechanical Properties: The standard defines minimum thresholds for tensile strength (typically ≥590is greater than or equal to 590 MPa for AlBC3), elongation ( ), and Brinell hardness.
Chemical Composition: It regulates the precise percentages of copper, aluminium, iron, nickel, and manganese. For instance, AlBC2 typically contains roughly aluminium and
Testing Methods: PDF documents of this standard typically outline procedures for tension tests (per JIS Z 2241) and hardness tests (per JIS Z 2243). Typical Industrial Applications
Materials produced to JIS H 5114 standards are prevalent in environments where high durability is critical: jis h 5114 pdf
Marine Engineering: Small to large marine propellers, sleeves, and pump impellers.
Mechanical Components: Bearings, bushings, valve seats, and gears.
Chemical & Oil Industry: Valve bodies and machine parts exposed to corrosive fluids. Where to Find the PDF and Modern Alternatives
Because this standard is officially inactive, official current copies are often unavailable for new procurement. Manufacturers now typically refer to the JIS H 5120 specifications for the most up-to-date guidance on copper alloy castings. For legacy documentation, engineers often access archived PDF versions through technical libraries or standard aggregators like JSA (Japanese Standards Association).

JIS H 5114 is the Japanese Industrial Standard for Aluminium Bronze Castings. While the document has been technically superseded by JIS H 5120 (Copper and copper alloy castings) and JIS H 5121 (Copper alloy continuous castings) in modern applications, it remains a critical legacy reference for engineering specifications and material data. What is JIS H 5114?
This standard specifies the requirements for aluminium bronze castings manufactured through various methods, including sand mould casting, metal mould casting, and centrifugal casting. Aluminium bronzes are a family of copper-based alloys that use aluminium (typically 5% to 12%) as the primary alloying element, which provides significantly higher strength and corrosion resistance compared to standard bronzes. Material Classes and Applications
JIS H 5114 categorizes materials into several classes based on their chemical composition and intended use:
Class 1 & 2 (AlBC1, AlBC2): Often used for smaller marine components like propellers, bearings, bushes, and valve seats.
Class 3 (AlBC3): Specifically designed for large castings requiring high strength and extreme resistance to corrosion, erosion, and abrasion.
Class 4 (AlBC4): Utilized for heavy-duty marine propellers, sleeves, impellers, and specialized machine parts for the chemical industry. Chemical Composition (Table 2 Summary)
The standard sets strict limits on elements to ensure material integrity: Copper (Cu) Aluminium (Al) Nickel (Ni) Manganese (Mn) Class 1 8.0 - 10.0% 1.0 - 4.0% Class 2 8.0 - 10.5% 2.5 - 5.0% 1.0 - 3.0% Class 3 8.5 - 10.5% 3.0 - 6.0% 3.0 - 6.0% Key Mechanical & Physical Properties
Materials produced under JIS H 5114 are valued for their specific physical characteristics: The keyword JIS H 5114 refers to a
Tensile Strength: High yield and tensile strengths, especially in Class 3 and 4 alloys.
Hardness: Typically measured via Brinell hardness; for example, AlBC2 often shows a hardness ≥142is greater than or equal to 142
Corrosion Resistance: Excellent performance in seawater environments, making it a standard for marine engineering.
Physical Constants: The standard also covers modulus of elasticity, thermal conductivity, and density. Why Search for the JIS H 5114 PDF?
Engineers and manufacturers often seek the JIS H 5114 PDF to verify legacy part specifications or to find equivalent modern grades. While the Japanese Standards Association (JSA) is the official publisher, many technical databases like GlobalSpec and Scribd provide historical summaries and data sheets for these materials.
For current projects, it is recommended to reference JIS H 5120, which now incorporates the specifications previously found in H 5114.
JIS H 5114 is the Japanese Industrial Standard for Copper and copper alloy continuous castings. This standard specifies the requirements for materials produced through continuous casting processes, such as rods, tubes, and special shapes made of copper or copper alloys. Core Technical Requirements
Based on technical documentation, the standard covers several critical inspection and material criteria: Mechanical Testing:
Tension Test: Conducted following the JIS Z 2241 method, typically using a No. 4 test piece. Hardness Test: Performed according to JIS Z 2243 standards.
Chemical Analysis: General rules and sampling methods are governed by JIS H 0321.
Sampling Protocols: One specimen is generally required per "run" of continuous casting for products of the same composition and shape. Typical Applications
Materials conforming to JIS H 5114 are frequently used in heavy-duty industrial components, including: Revision Control – Using an outdated version of

JIS H 5114 is a Japanese Industrial Standard (JIS) titled "Brass castings for valves, flanges and fittings". It specifically covers copper-zinc alloy (brass) castings used under pressure for water, oil, gas, and steam services.
The standard was originally established to unify the quality of brass castings produced by foundries across Japan. Today, it is referenced globally, especially in projects involving Japanese-designed equipment, shipbuilding, plumbing systems, and industrial machinery.
Searching for a free PDF of an industrial standard is common, but there are several reasons why obtaining the official or legitimate copy matters:
The standard specifies minimum requirements for:
Crucially, the PDF notes that these values are for standard test specimens, not the actual produced part. Real castings may vary due to porosity.
