What are the ingredients of 90-degree long-diameter elbow copper fittings?

In complex and changeable pipeline systems, 90-degree long-diameter elbow copper fittings, as key connection components, carry the diversion function of the fluid. They have also won wide application and recognition due to their unique material properties and good performance.

90-degree long-diameter elbow copper fittings are mainly made of pure copper or copper alloy. Pure copper is also called red copper. It is a metal with a very high copper content. Its chemical symbol is Cu. It has extremely high electrical conductivity, thermal conductivity and good ductility. In pipeline systems, pure copper is often used to make high-end, high-quality copper pipe fittings due to its good corrosion resistance and weldability.

In order to further improve the performance of the elbow, such as strength, hardness and wear resistance, copper alloy is used as the raw material. Copper alloy is a metal material with special properties formed by adding other metal elements (such as zinc, tin, nickel, aluminum, etc.) on the basis of pure copper. These alloy elements can change the physical and chemical properties of copper, making it more adaptable to specific working environments and requirements.

In 90-degree long-diameter elbow copper fittings, the role of alloying elements cannot be ignored. The addition of zinc can improve the strength and hardness of copper while maintaining a certain ductility and corrosion resistance; the addition of tin can improve the wear resistance and fatigue resistance of copper; the introduction of nickel can enhance the corrosion resistance of copper, especially in high temperature, high pressure or corrosive media; and the addition of aluminum helps to reduce the density of copper and improve the processing performance of the material.

In order to ensure the stable and reliable performance of 90-degree long-diameter elbow copper fittings, the content ratio of various elements in the raw materials is strictly controlled, which usually requires precise chemical analysis and strict process control. In the production process, the key indicators such as the dimensional accuracy, wall thickness uniformity, and surface finish of the elbow are strictly tested and controlled to ensure that the quality and performance of the product meet the relevant standards and requirements.

The 90-degree long-diameter elbow copper fittings can play an important role in the pipeline system, which is inseparable from its unique composition and good performance. Whether it is pure copper or copper alloy, its unique physical and chemical properties provide a solid foundation for the elbow.
