Problems solved by technology

At present, the tantalum plate produced is prone to cracking, wrinkling, orange peel, earing and other phenomena when deep drawing and drawing the tantalum shell. The yield is low, and it is difficult to meet the requirements of high performance and high reliability.
Conventional metalworking fluids are used for tantalum plate processing, which can reduce the wear of the metal and the mold, and slightly improve the surface appearance of the tantalum plate after processing. However, after a period of use, the tantalum plate is easy to stick to the mold. Therefore, it is urgent to develop a special tantalum plate processing fluid. Provide reference for the processing and production of tantalum plates
