Processing Cova alloy needs attention processing matters

Covar alloy, usually refers to nickel-based superalloy and corrosion resistant alloy, is an iron-nickel-cobalt based hard glass joint alloy widely used in the world. This alloy has a linear expansion coefficient similar to that of glass in the temperature range of 20 ° C to 450 ° C, so it can be effectively sealed with hard glass gaps. Due to its excellent low temperature microstructure stability, Corva alloy can maintain good performance in a variety of extreme environments. In addition, it can also be brazed with copper or steel components, increasing the flexibility of its application.

The oxide film formed on the surface of Covar alloy is very dense, which makes it have strong plasticity, can be cut, and is easy to weld. These properties make Kovar alloy an ideal material for the manufacture of electric vacuum components. It is worth mentioning that due to the cobalt element contained in the alloy, the components made have higher wear resistance, which is a significant advantage in industrial applications.

However, in the processing of curva alloy, the following points need to be noted:

Covar alloy has good plasticity, which can be a difficulty in CNC (computer numerical control) machining. Because the material is easy to adhere to the tool, the processing process is not smooth. In order to overcome this problem, special coated tools are needed to ensure that the processing quality is not compromised.

The hardness of the material is higher, which means that the tool wear rate will be very fast during processing. Although specially coated tools can extend the service life, they are usually more expensive. If the tool is worn too fast, it will not only increase the cost, but also may affect the processing efficiency and quality.

The challenge is particularly difficult when machining Corva alloy parts that require small holes to be punched. Due to the characteristics of the material, one hole may need to break multiple tools, which is an extremely challenging task for the processor.

Although Covar alloy has many excellent physical and chemical properties, it still needs to be handled carefully during processing to ensure the quality of the final product. By using the appropriate tools and techniques, the problems encountered during processing can be effectively solved, thus making full use of the advantages of this material
