ASTM B108 is a standard specification for permanent mold castings of aluminum alloys, but it should be noted that the expression “permanent model” is not directly included in the official name of the standard, but more broadly covers the standards and requirements for permanent mold castings of aluminum alloys. The following is a detailed interpretation of the ASTM B108 standard for permanent mold castings of aluminum alloys: 1. Overview of the standard Standard number: ASTM B108 (and its subsequent revisions, e.g., ASTM B108/B108M-XX) Scope of application: The ASTM B108 standard applies to specified permanent mold castings of aluminum alloys, which are typically used in general industrial applications, but may not be suitable for high-load or safety-critical applications that may require more stringent mechanical property and integrity testing. Alloy and temper designations conform to the uniform numbering system of ANSI H35.1 and its revisions (ANSI H35.1/H35.1M). Second, the main requirements Material requirements: specify the type, composition and performance requirements of aluminum alloy materials used in castings. Production requirements: including mold design, pouring temperature, cooling rate and other critical control points in the production process to ensure the quality and performance of castings. Quality Control: The quality control measures of castings in the production process are described in detail, such as defect detection, dimensional inspection, chemical analysis, etc. Test method: It stipulates the various tests that need to be carried out on castings, such as mechanical property testing, chemical composition analysis, non-destructive testing, etc., to ensure that the castings meet the requirements of the standard. Acceptance criteria: The specific requirements that should be met by the casting during acceptance are clarified, including appearance quality, dimensional accuracy, performance indicators, etc. Third, the field of application ASTM B108 Aluminum Alloy Permanent Mold Castings are widely used in various industrial fields, such as automobile manufacturing, machinery and equipment, building components, etc. They are favored for their excellent mechanical properties, corrosion resistance, low density, and good casting properties. 4. Precautions When using the ASTM B108 standard, the terms and requirements of the standard should be carefully read and understood to ensure that the production and quality control of castings meet the requirements of the standard. At the same time, attention should also be paid to the applicability and limitations of the standard, and avoid applying the standard to areas or situations that are not suitable. In summary, ASTM B108 is an important standard specification for aluminum alloy permanent mold castings, which provides comprehensive guidance for the production, quality control, and acceptance of castings.Huanickel?related?products?strictly?implement?this?standard.?For?more?information?about?the?standard?and?the?corresponding?product?information,[email protected] |
