| titleOfInvention | Production process of copper-aluminum composite decorative material |
| abstract | The invention discloses a production process of a copper-aluminum composite decorative material, belonging to the technical field of new materials, and the production method of the copper-aluminum composite decorative material comprises the following steps: (1) plating tin on one side or two side surfaces of the copper plate to obtain a copper plate blank with a tin plating layer; (2) and facing the tin-plated layer of the copper plate blank with the tin-plated layer to an aluminum plate, performing hot rolling compounding with the aluminum plate, performing heat treatment, and performing cold rolling to obtain the copper-aluminum composite decorative material. The production method simplifies the production process, is energy-saving and environment-friendly, reduces the production cost, is suitable for the compounding of copper plates of any brands and 1-series, 3-series, 4-series, 5-series, 6-series, 7-series or 8-series aluminum plates, has the compounding rate of 100 percent, the peel strength of more than or equal to 12N/mm, the thickness ratio of copper clad layers in the copper-aluminum composite decorative material of less than or equal to 15 percent, the tensile strength of 110-300 MPa and the elongation of more than or equal to 25 percent, and is suitable for preparing wide and high-strength copper-aluminum composite decorative materials. |
