Product Description
1.Characteristics and applications of aluminum-steel clad metals (aluminum-steel explosive clad metals, aluminum-steel explosive welded block) 

Although some engineers have had success in spot welding steel and aluminum together, it has largely been considered difficult to achieve reliable, continuous welds directly between the two dissimilar metals. That changed, however, when explosion welding was developed for doing that very thing.
Explosive welding is considered to be a solid-state welding process that uses controlled explosive energy to force two or more metals together at high pressures. The resultant composite system is joined with a high-quality metallurgical bond.
With other advantages like high efficiency, low cost and less requirement in equipment, explosive welding would be the optimal choice for welding aluminum to steel.
Its technical performance index as following: shear strength≥ 300N/mm2;according to the special requirements for products, such as the clad plate used for Petrochemical hydrogenation unit, conjoint ratio can reach 100%; interface shear strength>196MPa; the thickness of cladding layer 1~2mm, can be more thicker, the thickness of backer ≥1mm. The size of clad steel plate is not limited by explosive welding technical.

Characteristics and advantages of aluminum-steel clad metals (aluminum-steel explosive clad metals,aluminum-steel explosive welded block)

Light Weight: density of steel is around 7.85g/cm3,the density of aluminum is around 2.7g/cm3, only 1/3 of steel. Aluminum-steel clad metals can save energy; they can be used to make plane parts, vehicles, ships, etc. Due to aluminum-steel clad metals has aluminum's characteristics as well as steel's strength, the structures made by this clad metals have been widely used in many industries.

Corrosion resistance: when aluminum-steel clad metal is in the air, or in the deep sea, aluminum surface can't be rusty since its self-recovery. So, its performance is much better than normal galvanized steel, galvalume steel, painted steel. The corrosion resistance performance of aluminum-steel clad metal is 60 times than galvanized steel, and 20 times than galvalume steel, and 100 times than painted steel. Because of aluminum's affinity to the oxygen in the air, when aluminum is exposed in the air or in the deep sea, its surface can generate a natural protective oxide film layer with strong adhesion, and dense in a short time. The thickness of oxide film is around 0.01~0.05mm, this characteristic makes the aluminum has self-recovery function after its surface is scratched.

Excellent formability: after heat treating, aluminum-steel clad metals can be used to make lots of products such as tubes, tanks and pots by punching, blanking and welding.

High strength: aluminum-steel clad metals processed by explosive welding, has steel's strength as well as aluminum's characteristics, and its strength can be comparable with quality alloy steel.

High heat conductivity: aluminum heat conductivity is high, just next to copper, around 60% of copper coefficient of heat conduction; however, the same weight of copper and aluminum, aluminum is better than copper in coefficient of heat conduction. Whatever heating or cooling, aluminum is a very good preferred medium transmitting heat. Therefore, aluminum-steel clad metal is widely used in food industry, chemical industry, petroleum industry, and aviation industry. Aluminum-steel clad metal is preferred material producing metal kitchen ware.

High electric conductivity: aluminum is one of the only two high electric conductivity metals. The electric conductivity of conductive-aluminum is 62% of international standard copper, but the density of aluminum is only 1/3 of copper. This makes the electric conductivity of unit weight of aluminum is two times of unit weight of copper. The characteristics of heat conductivity, difference in electrode potential(DEP) are the key points of producing heat & electrical materials and multi-clad metals, such as these metals, aluminum-steel clad metal, aluminum-steel explosive welded block, aluminum-copper clad metal, aluminum-titanium clad metal, etc.

Strong light reflectivity: aluminum-steel clad metals have strong reflection to the radio waves, visible light, and infrared wave, such all the electromagnetic waves. The reflectivity is above 80% to white light.

No low - temperature brittleness: aluminum-steel clad metals can be used to low-temperature structure materials, such as, aluminum-steel transition joints.

Nuclear radiation resistance: with aluminum neutron has small absorption sectional area, aluminum-steel clad metals apply for thermal neutron reactor.

Good absorption in impact waves:  with good bump function and good absorption in impact waves, aluminum-steel clad metals apply to lightweight parts for automobiles.

Non-magnetic: when aluminum-steel clad metals are impacted, no sparks and static electricity. This makes aluminum-steel clad metals can be shielded materials in some special applications, or used for inflammable and explosive equipments and instruments.

Weldable: after inert gas arc welding, aluminum-steel clad metals have good appearance, corrosion resistance, and mechanical properties, which can meet the requirement of welding structure production.

No toxicity: aluminum-steel clad metals are unharmful to living body.

Good recycling: since different material dissolution ratio, fragments, and scraps of aluminum-steel clad metals are easy decomposed, melted, and recovered; and recycling only needs 3% of energy consumption.

Functions: aluminum-steel clad metals have these functions: protection, decoration, shielding, etc, as well as the following advantages: high hardness, wear resistance, electrical insulation, electromagnetic, resistance magnetic shielding, photo electricity, hydrophilic, corrosion resistance, etc.

Good resistance to high temperature: high temperature performance of aluminum-steel clad metals is almost the same compared with the stainless steel 316L.

Long lifetime: the lifetime of aluminum-steel clad metals can last more than 60 years.

Thermodynamics stability: aluminum-steel clad metals on the structure, take full consideration to optimize coefficient of linear expansion, hardness, melting solid point, moisture, elastic modulus, electrode potential, and thermal combined mechanical stability related to long lifetime among different materials; these make steel belt (or copper belt, titanium belt, etc.) its surface layer formed amorphous mixed with nanocrystalline aluminum-nickel-iron alloy.


Noise reduction and sound insulation: aluminum-steel clad metals can be changed surface structure, and processed internal foam pores to reduce noise and insulate sound according to the market requirements.

2.Applications of aluminum-steel clad metals (aluminum-steel explosive clad metals, aluminum-steel explosive welding block)

In the field of transportation industry: with the strong strength of steel, and good electric corrosion resistance, good electric conductivity of aluminum, aluminum-steel clad metals can make production parts, aluminum-steel stators, bimetal bearings, bimetal bushes, and bimetal liner tubes, etc. In the projects of high-speed trains, metros, aluminum-steel clad plate (aluminum-steel clad inductive board) can used as conductive sheet of linear induction motors. 

In the field of shipbuilding industry: because of the lightweight, corrosion resistance of aluminum, and strength of steel, aluminum-steel clad metals have been used broadly in shipbuilding. Aluminum-steel transition joints are not only used in shipbuilding industry, but also can be used as transition parts between special metals in other industries, such as machinery, electric power, nuclear energy, etc.

In the metallurgy industry: aluminum-steel clad metals can make cathode, and anode materials, and transition joints.

In the electric power industry: aluminum-steel/copper-steel clad metals have both characteristics of aluminum/copper in lightweight, good electric and heat conductivity, and steel in excellent mechanical properties. Therefore, aluminum-steel explosive welding transition block, copper-steel explosive welding transition block and aluminum-steel transition joints, copper-steel transition joints are used widely.

In the marine engineering industry: aluminum-steel clad metals, and nickel-steel clad metals can make steel structure of main body H-section steel, hull steel structure, bridge steel structure, ocean platform structure, ship's tanks, and so on.

In the fields of kitchen ware and heat exchanging: aluminum-steel clad metals have good heat conductivity, easy processing, can be widely used in heat exchangers, electric cookers, air coolers, and so on.
