High-end electronic products such as mobile phones will become more intelligent, lighter and more durable because of China Baowu’s steel products. On May 12th, two new products, 0.07mm ultra-flat stainless steel precision strip and stainless precision strip with no texture surface, were launched in the world by China Baowu Taigang Group.
The world’s first 0.07mm ultra-flat stainless steel precision strip is the key structural component of mobile phones-backlight material. With the rapid development of 5G communication technology, the lightweight of backlight materials has increasingly become a new development trend, and the demand for developing a new generation of backlight materials is increasingly urgent. Many mobile terminal brands at home and abroad have put forward new and more demanding requirements on flatness, strength and magnetism of stainless steel strips for mobile phone midplane, camera base and other internal components. Aiming at the market opportunity, TISCO has successfully developed a whole set of process technology after one year of tackling key problems. The flatness of the plate is below 0.1mm/m and the strength is above 1200MPa, achieving the goals of ultra-thin thickness, ultra-high strength and ultra-flat plate shape. At present, the product has entered the mass production stage and has a good market prospect.
Non-textured surface stainless precision strip steel is an advanced stainless steel material with high surface grade, which is developed and produced to solve the problem that the clarity of micro-two-dimensional code sprayed on conventional cold-rolled surface parts of stainless steel can not meet the requirements of intelligent identification in the intelligent manufacturing process of internal structural parts and components of high-end electronic products. Non-textured surface stainless precision strip steel greatly reduces the difference of transverse and longitudinal roughness and glossiness of the surface of stainless precision strip steel, realizes the high consistency of the surface, and solves the problems of identification and identification of parts processed by electroplating and spraying in the deep processing of strip steel. At present, it has passed the product application test of well-known enterprises and entered the mass production stage.
