Outokumpu 4120 Lamination Plate for HDI Board Production

1.Product Features

· Excellent Wear Resistance: The 4120 laminated steel plate has a high - hardness wear - resistant layer on its surface. During the lamination and usage process, it can effectively resist various mechanical actions such as friction and scratching. This reduces material loss and performance degradation caused by wear, extends the service life of laminated products, and is particularly suitable for application scenarios with high requirements for wear resistance. For example, printed circuit boards may undergo various friction operations during the production process, and the 4120 steel plate can handle them well.

· Good Electromagnetic Shielding Function: In the lamination applications of the electronics industry, the electromagnetic shielding function of the 4120 laminated steel plate is of crucial importance. It can effectively block external electromagnetic interference, avoid the impact of electromagnetic signals on the internal electronic components of laminated products, ensure the normal operation of electronic equipment, and improve the reliability and stability of the electronic system. For some electronic products with high requirements for electromagnetic compatibility, such as the laminated components of high - end communication equipment and precision instruments, this functional advantage is remarkable.

· Convenient Processing and Welding Performance: The good weldability and workability of the 4120 laminated steel plate bring great flexibility to its lamination and usage. Its easy - to - weld feature makes it convenient to connect with other metal or non - metal materials to form complex laminated structures. The excellent workability allows for processing in various shapes and sizes according to specific lamination requirements, such as cutting, stamping, and bending, enabling customized production and meeting the diverse design requirements of different laminated products.

· Enhanced Corrosion Resistance: Its composition may contain some elements with corrosion - resistant properties, such as chromium and nickel. This endows the 4120 laminated steel plate with certain corrosion resistance during the lamination and usage process. It can resist the erosion of moisture, chemicals, etc. in the external environment, prevent the steel plate surface from rusting or corroding, thus avoiding adverse effects on the performance of the laminated structure, and improving the service life and reliability of laminated products. This is especially applicable to laminated products used in some harsh environments.
