ASTM B26/ASTM B26M is a standard specification for aluminum alloy sand castings, and the following is a detailed interpretation of the standard: 1. Overview of the standard Standard number: ASTM B26/B26M Scope of application: This standard covers specified aluminum alloy sand castings, but it is expressly not applicable to aluminum alloy sand castings used in aerospace applications. Second, the main requirements Units The standard provides both the International System of Units (SI) and the inch-pound numerical system. The values specified in each system should be considered as standards separately and should not be mixed, as the values in each system may not be the exact equivalent. Performance & Requirements This standard puts forward specific requirements for the chemical composition, physical properties, mechanical properties, surface quality, dimensional tolerances and other aspects of aluminum alloy sand castings. Manufacturers need to carry out production and quality control in accordance with the requirements of the standard to ensure that the products meet the specified performance indicators. Acceptance criteria Detailed guidelines and references are given in the standard for the acceptance criteria for new aluminum and aluminum alloys and their properties in this specification. Safety & Health The standard does not cover all safety issues associated with its use. It is the responsibility of the user of the standard to develop appropriate safety and health practices prior to use and to determine the applicability of regulatory restrictions. Third, the field of application Aluminum and its alloy castings are widely used in many fields due to their excellent physical and chemical properties. Here are some of the main application areas: Automotive industry: Aluminum alloy castings are used in automobile manufacturing to make engine parts, chassis parts, body structural parts, etc., to reduce vehicle weight, improve fuel economy and reduce emissions. Aerospace: Aluminum alloy castings are widely used in the aerospace field because of their high strength, low density and good corrosion resistance, such as manufacturing aircraft fuselages, engine parts, etc. Machinery manufacturing: In the machinery manufacturing industry, aluminum alloy castings are used to manufacture various mechanical parts and components, such as pump bodies, valve bodies, transmission parts, etc. Construction industry: Aluminum alloy castings are used in the construction field to manufacture door and window frames and curtain wall support joints 4. Precautions When using aluminum alloy sand castings, users should fully understand the performance and characteristics of the product, and install and use them in accordance with the standard requirements. Especially when it comes to critical or important applications, special attention should be paid to the quality control of the product and compliance with the acceptance criteria. ASTM B26/B26M is an important standard specification for aluminum alloy sand castings, which provides users with detailed product requirements and performance indicators to ensure the quality and reliability of the products. By following this standard, manufacturers can produce high-quality aluminum alloy sand castings that meet the needs of various industrial applications in line with market demand.Huanickel?related?products?strictly?implement?this?standard.?For?more?information?about?the?standard?and?the?corresponding?product?information,[email protected] |
