Production process for C17000 beryllium copper hexagonal bar

The production of beryllium copper C17000 hexagonal bar is a highly precise technology. First， in a high-purity furnace， the copper and other elements such as boron and cobalt are melted together to form a metal alloy in beryllium copper C17000 hexagonal bar， ensuring uniform composition. Then，beryllium copper C17000 is shaped into billets through continuous casting or forging processes， taking on the initial form of the product. The key step is heat treatment： the material of beryllium copper C17000 is first subjected to annealing treatment (heated to approximately 800°C and slowly cooled) to soften the structure for easier processing； then it undergoes age hardening (held at 300-350°C for several hours) to stimulate the boron precipitates， significantly enhancing the strength. The entire process requires strict control of temperature and time to avoid oxidation or impurity intrusion. Modern techniques also incorporate vacuum melting and precise rolling to ensure that the micro structure of the beryllium copper C17000 material is dense and the performance is consistent. This production process not only gives beryllium copper C17000 hexagonal bar extremely high toughness but also makes it a recyclable and environmentally friendly option.

The unique design of the C17000 beryllium copper hexagonal bar

The design of the C17000 beryllium copper hexagonal bar is based on the pursuit of maximizing the utilization efficiency of the material. Compared to the circular bar, the C17000 beryllium copper hexagonal bar provides more edges on its cross-section. These edges can effectively disperse stress when subjected to pressure, thereby enhancing the overall strength of the C17000 beryllium copper. At the same time, the hexagonal shape also makes the material more compact when stacked and stored, reducing waste of space.
