Title: Class 12 alloys: excellent mechanical and physical properties, wide range of applications and material advantages.
Class 12 copper alloys, with their excellent mechanical and physical properties, have a wide range of applications in many industrial fields. In this paper, the chemical composition, heat treatment process, mechanical properties, physical properties and application fields of Class 12 copper alloys are introduced in detail, and its unique material advantages are summarized.
1. Chemical composition analysis.
Class 1 copper alloys, also known as brass, are mainly composed of copper (Cu) and zinc (Zn) and typically contain between 35% and 61% zinc. Depending on the application, other elements such as aluminum (Al), silicon (Si), manganese (Mn), etc., are added to the alloy to improve its properties.
2. Heat treatment process.
Heat treatment is a key process to improve the properties of Class 12 copper alloys. In general, Class 12 copper alloys go through two main steps: solution treatment and aging treatment. Solution treatment is to heat the alloy to the appropriate temperature so that the zinc element in it is fully dissolved into the copper, so as to improve the plasticity and toughness of the alloy. Aging treatment is to cool the alloy to room temperature or slightly higher than room temperature after solution treatment, so that the zinc element in the alloy is precipitated in the crystal form, so as to further improve the strength and hardness of the alloy.
