The naming conventions for special bronze alloy grades may vary from one standard organization to another, but they usually contain some common elements. Here are some common naming conventions:
Element designation: The grade usually starts with the chemical symbol of the main alloying element, such as "Cu" for copper, "Sn" for tin, "Zn" for zinc, etc.
Content designation: The content of the alloying element is usually expressed as a percentage, immediately following the element symbol. For example, the "8" in "CuSn8" means it contains 8% tin.
Alloy type: Some grades may include information indicating the alloy type, such as "Al bronze" for bronze alloys containing aluminum.
Added elements: If special elements are added to the alloy, the chemical symbols of these elements may be included in the grade, sometimes followed by the content or a specific numeric code.
Numerical code: Some standard organizations may use specific numeric codes to distinguish different alloy variants or specific production processes.
Country or region code: In some cases, the grade may include the country or region code indicating the standard, such as "GB" for Chinese national standards.
UNS number: The Unified Numbering System (UNS) provides a globally unique digital identification code for materials. These numbers usually begin with "S" or "C" and are followed by five digits.
Sequential number: Some standards may assign numbers based on the order in which the alloys were developed. These numbers may not have specific element or content meanings.
Performance characteristics: In some cases, the grade may include words that indicate specific performance characteristics of the alloy, such as "wear-resistant", "corrosion-resistant", etc.
Special marking: Some special bronze alloys may have special markings or suffixes to distinguish their specific uses or characteristics.
It should be noted that different countries or regions may have different naming habits and rules, so it is very important to understand and use these grades correctly in international trade and technical exchanges. In addition, with the development of new materials and the update of standards, the naming rules of grades may also change.
