Title: Class 11 alloy: A comprehensive interpretation of its characteristics and application fields.
1. Introduction. Class 11 copper alloy, also known as beryllium copper alloy, is an alloy based on copper with an appropriate amount of beryllium, nickel, manganese, zinc and other elements added. Due to its electrical conductivity, thermal conductivity and plasticity, as well as good corrosion resistance, fatigue strength and elastic modulus, it is widely used in electronics, electrical, communications, automobiles, precision instruments and other fields.
2. Chemical composition analysis.
The main chemical constituents of Class 11 copper alloys include copper (Cu), nickel (Ni), manganese (Mn), zinc (Zn), and beryllium (BE). Among them, the content of copper is about 70%, the content of nickel is about 15%, the content of manganese is about 1%, the content of zinc is about 10%, and the content is about 2%.
3. Heat treatment process.
The heat treatment process of Class 11 copper alloy mainly includes solution treatment and aging treatment. The purpose of solution treatment is to dissolve the beryllium element in the alloy in the copper body to improve the strength and hardness of the alloy. Solution treatment is usually carried out at 750-850, and the holding time depends on the thickness of the alloy. The purpose of aging treatment is to precipitate the solute elements in the alloy to form a stable strengthening phase and further improve the strength and hardness of the alloy. The aging treatment is usually carried out at 150-200 °C, and the holding time depends on the thickness of the alloy.
