Composite materials are made from two or more component materials with significantly different physical or chemical properties, prepared by physical or chemical methods and having new properties, and the component materials remain distinguishable on a macroscopic level. The component materials produce a synergistic effect, therefore the composite materials has compositive properties which are better than the component materials. Composite materials are widely used in aviation, aerospace, automotive, medical, chemical, textile, machinery manufacturing, construction, low-voltage electrical Industries and other fields.
Mastered the metal room temperature continuous solid-phase composite surface treatment, solid-phase composite, diffusion annealing and cold rolling processing and other key preparation technologies, to determine the main production process parameters of composite metal. Developed resistance-type double-layer, three-layer and other composite hot bimetallic strips, product size and performance are at the leading level.
