Tiantong Co., Ltd.'s performance has grown steadily, and its equipment business has increased its flexibility.

At the material end, magnetic materials focus on new energy and automotive electronics, and sapphire materials are vigorously expanding production. The company's magnetic materials are deployed in many fields. Many automotive electronics products have passed vehicle regulatory certification. Applications in the automotive field are gradually increasing. It vigorously develops the metal soft magnetic business. 80% of the new products developed are used in the automotive and new energy fields. Applications in the photovoltaic field are growing rapidly. The photovoltaic micro-inverter business in the electronic manufacturing service segment is growing rapidly. Sapphire Materials Company has obvious core advantages. It uses C-directed crystal growth technology to mass-produce 400kg sapphire large crystal ingots. New applications of Mini and MicroLED have boosted the demand for sapphire. The piezoelectric crystal material company has maturely produced 6-inch surface acoustic crystals and blackened polished wafer products, and has developed 8-inch piezoelectric crystal materials. It has stable cooperation with customers such as Haoda Electronics and China Electronics 26th Institute, and the process of domestic substitution continues.
