The P675R bimetallic strip (0.16mm×27mm), a precision-engineered functional material from Huona New Material, is a specialized composite strip composed of two dissimilar alloys with distinct thermal expansion coefficients--firmly bonded via our proprietary hot-rolling and diffusion bonding technology. With a fixed thin gauge of 0.16mm and standard width of 27mm, this strip is optimized for miniaturized temperature-sensitive applications, where precise thermal actuation, stable dimensionality, and space-saving design are critical.
