Three Core of the Copper One

Copper aluminum composite plate strip

Technique Testing Environment

Process research and development

Equipped with advanced machinery, comprehensive testing methods, formidable technical prowess, and superior production processes, the Company owns over 50 sets of specialized composite equipment, employs 35 engineering technicians, and has established long-term strategic partnerships with the Institute of Mechanics, Chinese Academy of Sciences and Henan University of Science and Technology. It houses the Academician Workstation for Metal Composite Material Technology Research in Henan Province, the Henan Provincial Engineering Technology Research Center for Metal Composite Materials, holds ISO9001 quality management system certification, has secured National Torch Program project approval, and possesses technical enterprise credentials.

Comprehensive testing

Full-coverage material inspection: The number of electromagnetic transducers is determined based on the width of the copper plate. The transducers utilize high-frequency induction coils arranged in a staggered pattern. To ensure a 115% repeat coverage rate, multi-channel probes are overlapped for detection (with a 15% repeat coverage).When changing the specifications of the inspected copper-aluminum composite strip, fine-tuning the spacing of the sensors ensures effective electromagnetic field coverage.

Environment

Effective separation of production lines and spaces, transforming an inherently uncontrolled production environment into one with meticulously controlled dust, pollution, and particulate matter (PM) levels reduced to minimal values. We have developed and implemented a complete set of dust-proof measures, including vacuum evacuation equipment.

R&D and Manufacturing

Semi-molten rolling composite

Through continuous casting and rolling composite processes, utilizing aluminum ingots and copper strip as raw materials, the copper and aluminum reach a semi-melt state during the composite process, achieving 100% metallurgical bonding. The process is conducted under high temperature, high pressure, and oxygen-free conditions, addressing oxidation issues that may occur during the copper-aluminum composite process. It ensures precise control of the temperature and time required for thermal penetration between the two metals, regulating the formation and expansion of eutectic layers, resulting in high-strength copper-aluminum composites.

Triple System Certification

The company has obtained certifications for ISO9001 (Quality Management System), ISO14001 (Environmental Management System), and ISO45001 (Occupational Health and Safety Management System), thus completing the triple system certification.

Equipment Support

The quality laboratory is equipped with a range of standard professional testing devices, including spectrometers, universal tensile testing machines, 90-degree peel testers, 3D imaging measurement instruments, Vickers hardness testers, DC resistance testers, bending machines, roughness meters, hydrogen content analyzers, trace oxygen analyzers, as well as dedicated equipment for foil materials such as fold endurance testers, vertical tensile testing machines, twist testers, winding testers, drop testers, and a sample preparation room for processing specimens. The laboratory facilitates efficient and convenient testing of chemical properties, physical properties, and accelerated environmental aging tests for samples.

Characteristics and advantages of copper-aluminum composite transition plate

The copper-aluminum composite transition plate has low cost and light specific gravity: the composite product of the same volume can save customers at least 60% of the cost compared with pure copper; the specific gravity is 37%-40% of pure copper.

Analysis on investment prospects of copper-aluminum composite strip industry

Copper-aluminum composite belt is made of copper and aluminum through copper-aluminum composite technology. Therefore, copper-aluminum composite belt has both the aesthetics of copper and the corrosion resistance and low cost of aluminum. It is widely used in electronics, automobiles, energy, electrical appliances, petrochemicals, metallurgy, machinery and other industrial fields. As we all know, China is a country with more aluminum and less copper.

Advantages of copper-aluminum composite bar

Copper-aluminum composite busbars can also be called copper-clad aluminum busbars, copper-clad aluminum busbars or copper-clad aluminum busbars. As a high-tech energy-saving conductor material, copper-aluminum composite busbars have both the conductivity of copper and the low density of aluminum. The application of copper-aluminum composite busbars can be traced back to the 1960s. With the development of the economy, some European and American countries began to study and apply copper-clad aluminum materials and formulate conductor standards for the application of this material.

Copper-aluminum composite plate made by explosive composite method

At present, there are many methods for producing copper-aluminum composite plates, which can be generally divided into three categories: solid-solid composite method, liquid-solid composite method and liquid-liquid composite method. Explosion composite method, extrusion composite method, explosion welding hot rolling method, rolling composite method, diffusion composite method, diffusion welding method, etc., all belong to solid-solid composite method. Next, we will introduce the production of copper-aluminum composite plates by explosion composite method in detail.

What are the advantages of copper-aluminum communication substrates?

Copper-aluminum communication substrates are made of copper and aluminum using copper-aluminum composite technology. Therefore, copper-aluminum communication substrates have the characteristics of corrosion resistance and low cost, and are widely used in electronics, automobiles, energy, electricity, petrochemicals, metallurgy, machinery and other industries. Copper-aluminum communication substrates use foreign advanced bimetallic composite technology, with stable quality and reliable performance. They are high-tech energy-saving products that can replace copper and aluminum busbars.

Characteristics and investment prospects of copper-aluminum communication substrates

In recent years, Chinese steel enterprises have continuously enhanced their innovation awareness and increased their investment in research and development of copper-aluminum communication substrate materials, but there is still a gap compared with some international steel enterprises. The independence, coordination, systematization, stability and continuity of technological innovation in the steel industry are still insufficient, and the technology supply still cannot fully meet the development needs of the industry.
