The preparation methods of copper alloy processed products mainly include the following:
Casting: Casting is to heat the copper alloy material to liquid state, pour it into a pre-designed and made mold, and take it out after cooling and solidification. This method is suitable for producing complex and fine parts, such as artworks, sculptures and tools.
Rolling: Rolling is the basic method for producing copper and copper alloy plates and strips. The material is continuously deformed by the rotation of the roller, which is suitable for multi-variety and large-scale production.
Forging: Forging is to plastically deform the copper alloy material by applying external force to obtain the desired shape and performance. It is often used to make large parts or products with high material performance requirements.
Extrusion: Extrusion is to use pressure to squeeze the copper alloy material out of the mold, which is suitable for producing products with thin wall thickness and high precision.
Stretching: Stretching is to use tensile force to plastically deform the copper alloy material, which is suitable for manufacturing pipes, bars and wires.
Welding: Welding is a method of connecting two or more copper alloy parts together. Common welding methods include argon arc welding, TIG welding and MIG welding.
Machining: Cutting, drilling, milling and other processing of copper alloys by machine tools are suitable for manufacturing various parts and products.
Surface treatment: In order to improve the corrosion resistance, wear resistance and decorative properties of copper alloys, surface treatments such as electroplating, chemical plating and anodizing can be performed.
