high tensile strength and low cost rate steel clad copper clad steel with high performance cost ratio and high extensibility

A copper-steel composite material with good elongation, high bonding strength, low resistivity, high tensile strength and low cost is provided. A copper-steel-copper composite material is disclosed. Its chemical composition proportion is 5-20% of copper and 80-95% of steel, and its structure is composed of copper and steel. The invention also discloses the preparation method of copper-steel composite material. The preparation steps are as follows: after surface treatment, copper and steel are rolled into high-precision steel strip and high-precision copper strip by cold rolling mill; after surface cleaning, surface residues are removed and degreased; high-precision copper-steel composite strip is rolled by cold rolling mill; and copper-steel composite strip is annealed at 650-850 C in vacuum furnace. In 1-4 hours, the structural molecules of the composite layer of two kinds of metal materials are melted, and then cooled to room temperature in vacuum furnace; the two kinds of strips are compounded to make the strips compounded into one and finish rolling; the composite materials are smoothed and polished, and the strips are packed after shearing according to the requirements of users.

Advantages:

Brass Steel Composte Strip is new kind of high-new composite bimetal material. It extracts advantages from copper and steel, and combines all advantages perfectly. The new bimetal material owns properties as following:

1. Good Conductivity
2. Good corrosion resistance
3. High strength
4. Good formability
5. Good extension
6. same appearance
6. Lower cost

Parameters:

Application:

1. Military industry: Steel clad copper clad steel is used to replace the shell made of traditional steel and copper, which not only guarantees the original performance, but also has the characteristics of corrosion resistance and good surface lubrication.

2. Electronic industry: There are many gaskets in electronic components, which require strong and thin. Steel clad copper clad steel can meet various innovative design requirements.

3. Cookware industry: In the manufacture of kitchen utensils, a lot of extrusion deformation is needed. Steel clad copper clad steel has good strength and ductility, which greatly improves the processing efficiency of products.
