Aluminum bronze is prized for its high strength and exceptional resistance to corrosion, particularly in seawater environments, making it a staple in marine engineering and chemical processing. 2. Technical Specifications
If the older JIS standard is unavailable in your regional supply chain, cross-reference components with ASTM B148 (US) or EN 1982 (Europe) aluminum bronze equivalents.
Securing an official and authentic copy of any JIS standard is crucial for legal and technical accuracy. Here are the recommended approaches for obtaining JIS H 5114:1988:
Phosphor bronze alloys feature excellent wear resistance and a low coefficient of friction. They are predominantly used for heavy-duty bushings, gears, and bearings operating under high loads. 2. High Tensile Brass Castings (HBSC)
Heavy-duty sleeve bearings, synchronization rings, and bushings rely on the anti-friction properties of high-tensile brass. jis h 5114 pdf
: Components for gates, valves, and trash racks often utilize these bronze or copper alloy castings due to their durability.
Materials specified under JIS H 5114 are frequently used in heavy-duty and marine environments: 株式会社岡本 Small to large propellers, sleeves, and impellers. Industrial:
The standard categorizes aluminum bronze castings into distinct classes based on their specific chemical formulations and structural behaviors. The most common classifications are . JSA - JIS H 5114 - Aluminium Bronze Castings | GlobalSpec
The structural classification determines the operational environment for each casting type: Aluminum bronze is prized for its high strength
Improves corrosion resistance and strength, particularly at higher temperatures.
