Beryllium Copper Pipe

Beryllium copper pipes are high-performance tubular products made from copper-beryllium alloys. Known as the "copper alloy with the strength of steel," they combine exceptional mechanical properties with excellent electrical and thermal conductivity, making them indispensable in demanding aerospace, automotive, marine, and industrial applications

 

Beryllium copper is a precipitation-hardening alloy that achieves remarkable strength through heat treatment. The addition of beryllium (typically 0.2–2.0%) creates a material that can be harder than certain steel grades while remaining lightweight and formable

• Raw material preparation: For the production of beryllium copper CuBe1.7, high-purity copper and beryllium need to be prepared first. The quality of these two raw materials directly affects the performance of the final alloy. Ensuring the purity and proportion of raw materials is the crucial first step.
• Alloy melting: The prepared copper and beryllium raw materials are sent into a special induction melting furnace for alloy melting. In this process, by controlling the temperature and proportion of ingredients, it is ensured that copper and beryllium are fully mixed to form a uniform alloy liquid. The smelting process needs to be strictly controlled to avoid the introduction of impurities.
• Alloy casting: After melting, the alloy is cast into the desired shape, which can be a billet, bar, plate, etc. During the casting process, attention should be paid to controlling the cooling rate and solidification process to ensure a uniform crystal structure and improve the mechanical properties of the alloy.
• Heat treatment: After alloy casting is completed, heat treatment is usually required to improve its properties. Heat treatment includes solution treatment and aging treatment. Solid solution treatment involves heating the alloy to a sufficiently high temperature to uniformly dissolve its elements, and then controlling the cooling rate to form a uniform solid solution. Aging treatment is achieved by keeping the alloy at a lower temperature for a period of time, gradually increasing its hardness and strength.
• Cold processing: For applications with special requirements, beryllium copper CuBe1.7 may require cold processing, such as rolling, drawing, or forging. Cold working can further improve the mechanical properties of alloys while adjusting their size and shape.
• Surface treatment: The final product may require surface treatment such as polishing, pickling, or coating to meet specific application requirements. This helps to improve the corrosion resistance and appearance of the alloy.

 

• Solution treatment: 860-880 ℃ for 1-2 hours, air quenching to ensure uniformity of the substrate without precipitation.
• Time hardening: 300-330 ℃ for 2-4 hours, precipitation of strengthening phase to achieve the highest strength and hardness.
• Cold processing and hot processing: Combining high plasticity and plasticity, supporting stamping, deep drawing, and precision forming;
• Cutting: With the use of hard alloy cutting tools and high-pressure coolant, high-precision and high-efficiency cutting can be achieved;
• Surface treatment: Polishing, electroplating, or chemical plating can further enhance corrosion resistance and decorative effects.

 

• Outer diameter: Φ 1.0- Φ 50 mm (commonly available as Φ 2- Φ 20 mm)
• Wall thickness: 0.1-3.0 mm (precision thin walls can reach 0.1-0.5 mm)
