Copper casting refers to various parts or products made of copper alloy by casting process, which are widely used in many fields. The use of copper casting mainly has the following benefits:

Good physical properties

Excellent electrical conductivity: Copper has a very high electrical conductivity, second only to silver. This makes the copper casting in electrical, electronic and other areas with high conductivity requirements, such as wire and cable, transformers, electrical switches, etc., can efficiently transmit current, reduce power loss, and improve the operating efficiency and performance of the equipment.

Excellent thermal conductivity: The thermal conductivity of copper is also very good, in the need for rapid heat dissipation or heat exchange occasions, such as radiators, heat exchangers, molds, etc., copper casting can quickly transfer the heat out, ensure the normal operating temperature of the equipment, extend the service life of the equipment.

Higher density: The density of copper is larger, which makes the copper casting have a certain weight and texture, and can provide better stability and balance in some applications that require stable mass and center of gravity, such as mechanical counterweight blocks, sculptures, etc.

Excellent mechanical properties

Good strength and toughness: Copper and copper alloys have high strength and toughness, can withstand greater external force and impact, not easy to break. This makes the copper casting in the machinery manufacturing, automotive industry, aerospace and other fields, can be used to manufacture parts that bear higher loads and complex stresses, such as gears, bearing bushing, connecting rods, etc., to ensure the reliability and safety of equipment.

Good wear resistance: copper casting surface hardness is high, has good wear resistance, in the frequent friction environment, such as bearings, sliders, guides and other parts, can reduce wear, reduce the coefficient of friction, improve the operating efficiency and service life of the equipment.

Excellent corrosion resistance

Resistance to atmospheric corrosion: Copper can form a dense oxide film in the air, which can prevent oxygen and water from further eroding the copper matrix, so that it has good atmospheric corrosion resistance. Therefore, copper casting in the outdoor environment, such as architectural decoration, sculpture, power tower, etc., can maintain good appearance and performance for a long time, reducing maintenance costs.

Chemical corrosion resistance: Copper has good corrosion resistance to many chemical substances, in some chemical, Marine and other harsh environments, copper casting can be used to manufacture pipes, valves, pumps and other equipment, can resist the erosion of chemical substances such as acid, alkali and salt, to ensure the normal operation of equipment.

Good processing performance

Good casting performance: the fluidity of copper alloy is good, the shrinkage rate is small, and the mold cavity can be well filled in the casting process, forming complex shapes and high-precision castings, reducing the subsequent processing procedures, improving production efficiency and reducing costs.

Good machining performance: copper casting has good cutting performance, easy to turn, milling, drilling, grinding and other machining operations, can process a variety of precision and surface quality parts to meet the requirements of different fields.

Unique appearance and cultural value

Beautiful color: Copper has a unique metallic luster and color, ranging from golden yellow to purple, with a high decorative. Copper casting can be used in architectural decoration, household goods, art and other fields, such as door handles, lamps, sculptures, etc., can add unique artistic charm and cultural atmosphere to the product.

Cultural symbolism: In human history, copper has always had important cultural and historical value. The use of copper castings can inherit and carry forward traditional culture, reflect the cultural connotation and historical heritage of products, such as ancient bronzes, modern commemorative coins, etc., which have important cultural and collection value.
