Products Description

Bimetal al-cu double overlay clad sheet
AL-CU clad sheets are mainly used for copper-aluminum transitional connection, avoiding the direct connection of copper and aluminum to produce electrochemical corrosion between copper and aluminum, and the resistance increases, which leads to various power accidents caused by local heating of the circuit.

By controlling the contact time and temperature between aluminum and copper, we control the diffusion rate and time of copper and aluminum atoms. And this process allows them to be permanently and firmly bonded in an oxygen free environment, ensuring 100% metallurgical bonding.

It is Widely used in electronics, communications, electrical appliances, power, heat dissipation, automotive, architectural decoration, living appliances, conductive industry (a variety of electronic tape, shielded cable foil, etc.); thermal conductivity industry (various heat sinks, solar collectors, photovoltaic materials Wait).

3.Other advantages:
The copper clad aluminum sheets produced by sanxie adopt advanced rolling technology,It greatly improves the peel strength of the product,and does not crack and layering during processing, shearing, bending, stretching, drilling, and stamping.

There are two common configurations for overlay cladding metal, one is single overlay, and the other is double overlay. And we can also produce inlay cladding metals, one is single inlay , and the other is single edge inlay . In addition, we can also provide weld thru.

Why Choose Us


1.What is cladding?
A process that bonds one metal to another (or others) in order to achieve specific properties and application benefits, including economic.Typically, cladding is a continuous roll bonding process that dissimilar metals are diffused together to form an inseparable whole.Intense pressure creates a metallurgical bond at the atomic level so that the separate metals are joined through a common bonded structure with a shared electron surface.
2.Some misunderstandings about clad metal
Clad metal is not an alloy, not electroplated, not mechanically welded to another metal.The cladding process joins metals via high pressure and without brazing alloys or adhesives.It consists of layers of different metals.cladding allows many metal to be used which ordinarily could not be plated. Through careful selection of materials, a surface can be attained that is denser, harder and more wear resistant than a plated surface.
3.What is the impact that copper directly and mechanically connects aluminum?
When Aluminum terminals are directly connected to Copper Terminals,to carry current at a high voltage ,a bimetallic galvanic corrosion occurs, resulting in a high resistance at the joint. Heated joints are oxidized and loose in contact, resulting in sparks, voltage drops, power losses, and malfunctions, which damage the machinery.
4.What are the benefits of copper Clad aluminum Composite Materials?
Clad metals have a complete metallurgical bond that results in no increase of electrical or thermal resistance and permanent high strength. It not only has the advantages of good electrical conductivity, thermal conductivity, low contact resistance, easy electroplating and aesthetic appearance of the copper material, but also has the characteristics of light weight, excellent heat dissipation, and economical characteristics of aluminum materials.
5.What is the purpose of various welding methods?
Like cladding, various welding method are intended to fuse dissimilar metals together. Creating heat and transformation upon impact,they can be used to join dissimilar metals and alloys, of both precious and non-precious metals. Fusing component materials with different thicknesses, tempers, tensile strengths and conductivities is no problem for this process. Even metals with dissimilar melting points can be welded by this method, including refractory alloys.
6.What are the differences between inlays and overlays?
Inlays can be used to bond precious metals with less expensive materials. Through an inlay design, the properties of the precious metal can be targeted precisely and leveraged, while also integrating heat sinking and other specific benefits from the less expensive material. Inlays permit use of alloys that cannot otherwise be plated, but with all the advantages you would attain through plating.
Overlay cladding is a somewhat different process by which dissimilar layers of metals are bonded together, using extreme pressure (and sometimes heat) and no adhesives or fillers. Overlays can be single clad (two layers), double clad (three layers), or as many as seven layers.

7.What are the benefits of Overlay Clad Metal Composite Materials?
Clad metals often use one material on the surface (for corrosion resistance, weldability or other benefits) and a different material in the core to create other properties. Overlay cladding creates clads with a wide range of properties not found in mono-metals.
