Copper-steel metal composite material is a type of metal material formed by layering and combining two metal materials, copper and steel, with their respective performance advantages. After the material is compounded, it can overcome the respective shortcomings of the two metals and give full play to the advantages of both. The special properties of the compounded material can adapt to the harsh working environment, prolong the service life of the components, and improve the comprehensive economic benefits. Copper has excellent extensibility and excellent electrical and thermal conductivity. It is a commonly used industrial metal material and is widely used in many fields. However, copper has low strength, is easily deformed during use, and is expensive, all of which hinder the long-term development of copper and its alloys. The price of steel is low and the strength is high. After being compounded with copper, the use characteristics of copper can be fully utilized, and the strength is greatly improved. Copper-steel composite material has excellent comprehensive mechanical properties and good economic benefits.
According to the composite state of the two metals, the preparation process of copper-steel composite materials is mainly divided into two categories: the solid-liquid phase composite method and the solid-solid phase composite method. The solid-liquid phase composite method includes a casting composite method, centrifugal casting method, and continuous casting and rolling composite method; the solid-solid phase composite method includes a rolling composite method, explosion composite method, and diffusion composite method. At present, the explosive composite method, rolling composite method, and diffusion composite method are the most commonly used preparation methods. The composite materials have broad application prospects in the fields of electronics, military industry, metallurgy, nuclear energy, and even aerospace.
Baoji Taicheng Clad Metal Materials Co., Ltd is a metal composite material manufacturer. At present, the company has two complete production lines and two field explosion sites. Most of the metal-clad plates we provide use explosive cladding methods, such as copper-steel clad plates.
The explosive composite method refers to the use of the super-strong impact force generated by the explosion of the explosive on the metal to be composited, so that the two metal plates collide at high speed in an instant, and the exposed flesh and clean metal surfaces form direct contact, combined with the process of forming composite materials.
At present, the preparation of composite materials by the explosive composite method has been widely used, and large-area composite plates can be prepared with high production efficiency. The composite interface of the prepared material can realize good metallurgical bonding and has high interface strength, and can be used as the base plate of the copper-steel composite cooling wall. The limitation of the explosive composite method is that it requires a special explosion site during production, and it has certain dangers.
