Titanium material, as a high-performance material, has a long history of application and broad prospects in the field of photographic equipment. As early as 1953, Japan Optical Industries Corporation first used Titanium Materials as the metal curtain material for the focal plane shutter on the Nikon F camera. This innovative application benefits from the high temperature resistance, durability, aging resistance, lightweight, high bending stiffness, and impact resistance of Titanium Materials, making it an ideal choice to meet the stringent requirements of shutter curtains.
With the passage of time, the application range of titanium materials in photographic equipment has gradually expanded. In December 1990, the first pocket sized camera with an all titanium casing was launched, marking a significant breakthrough in titanium materials for camera casing materials. As a shell material, titanium not only needs to meet the above performance requirements, but also needs to have good surface uniformity and anti pollution ability. After overcoming technical challenges such as stamping processability, weldability, grindability, and stain resistance, the application of titanium material in camera housings has been realized, and the monthly amount of titanium used as housing material has exceeded 2 tons. The parts produced include front and rear covers, upper and lower covers, and lens protection covers.
However, with the continuous changes in the appearance of digital cameras, the growth space for the demand for exterior titaniu
