Abstract

The invention discloses a composite metal material. The composite metal material comprises a first metal plate and a second metal layer which wraps the outer surface of the first metal plate; and thethickness of the first metal plate ranges from 1 mm to 2 mm, and the thickness of the second metal layer ranges from 0.6 mm to 1.4 mm. According to the designed and developed composite metal material,the second metal layer wraps the outer surface of a first metal, the thickness of the first metal and the thickness of the second metal layer are optimized, and the comprehensive performance of the composite metal material is improved; and the invention further designs and develops a preparation method of the composite metal material, a second metal is atomized into liquid drops and sprayed on the outer surface of the first metal, and the rotating speed and the spraying speed of centrifugal atomization are accurately controlled, so that the second metal layer uniformly wraps the outer surfaceof the first metal, and the comprehensive performance of the composite metal material is improved.

Description

technical field [0001] The invention relates to the technical field of composite metal materials, and more specifically, the invention relates to a composite metal material and a preparation method thereof. Background technique [0002] With the continuous advancement of science and technology, it is difficult for a single material to meet the needs of modern industry for the comprehensive performance of materials. Composite materials have attracted more and more attention from the industry due to their performance designability. As important metal raw materials, aluminum and copper are widely used in industry and life. Aluminum has the characteristics of light weight, abundant resources in my country, and low price. Copper has excellent properties such as good electrical conductivity, thermal conductivity, corrosion resistance, and antibacterial properties, but copper resources are in short supply and expensive. If aluminum is used as the matrix and the outer layer is co...
