The base is a precision-engineered component with dimensions of 30x50cm, crafted from high-quality materials including CuZn39Pb1, C3600, CZ122, CuSn6, CA104, C10100, C12000, H62, and QSn7-0.2. Manufactured to a precision tolerance of 0.01mm, it is produced using advanced processing methods such as CNC turning and knurling. To enhance corrosion resistance and surface aesthetics, the base undergoes specialized treatments including nickel plating, zinc plating, chromium plating, blackening, and phosphate treatment.
