Aluminum-Steel Cladding: Unlocking New Value Across Diverse Applications
Phohom New Material employs explosive cladding technology to achieve metallurgical bonding between aluminum and steel, successfully producing a range of bimetallic connectors, including explosive welding block, shipbuilding transition joint, and cryogenic transition joint. Despite sharing the same fundamental principle of aluminum-steel bonding, how can differentiated products for various industries be derived? The answer lies in the combination of different aluminum and steel grades under tailored production standards, resulting in uniquely functional aluminum-steel cladding materials.
1. Al-St Explosive Welding Block
As an innovative connector, the aluminum-steel explosive welding block has effectively replaced traditional methods such as riveting and conventional welding, it is primarily used in prebaked electrolytic cells of aluminum smelters to connect aluminum guide rods and steel claws. Typically, the block is composed of 1070/1060 aluminum and Q235B steel.
The 1 series aluminum, with its pure aluminum matrix and no additional alloying elements, offers excellent electrical conductivity, thermal conductivity, and superior workability. Meanwhile, Q235B steel provides moderate strength, good toughness, and castability. This unique material combination endows the aluminum-steel explosive welding block with advantages such as low interfacial resistance, high bonding strength, and high-temperature resistance, making it an ideal transition joint material for electrolysis and power systems.
2. Al-St Shipbuilding Transition Joint
In industries with stringent lightweight demands—such as high-speed vessels, yachts, and naval ships—Phohom New Material meticulously selects 3, 5, and 6 series aluminum as cladding materials to produce high-performance aluminum-steel shipbuilding joints, enabling effective bonding of otherwise unweldable dissimilar metals. Commonmaterial combinations include 5083 + 1060 + CCSB/DH36/EH36 and 3003 + TA1 + CCSB.
The 3, 5, and 6 series aluminum exhibit excellent corrosion resistance and moderate strength, while marine-grade structural steel further enhances the product’s overall strength and durability, fully meeting the application requirements of this sector. Through independent innovation, Phohom has overcome critical challenges in length specifications for shipbuilding transition joints, pioneering the development of 6-meter-long aluminum-steel shipbuilding joints. This breakthrough significantly reduces welding frequency in shipbuilding and repair, boosting operational efficiency.
3. Al-St Cryogenic Transition Joint
Aluminum-steel cryogenic transition joints are primarily used in low-temperature engineering applications such as air separation units, liquid nitrogen, liquid oxygen, and liquefied natural gas (LNG) systems. Common material combinations include 5083 + 1100 + TA1 + N02200 + 304/316L and 1050/1060/1070 + TA1 + 304/316L.
Leveraging the detonation pressure generated by explosive cladding, Phohom achieves metallurgical bonding of up to five layers across multiple materials, including 1,5 series aluminum and stainless steel. This distinctive bonding method ensures the product exhibits high strength, pressure resistance, and an operational temperature range of -196°C to +65°C, with potential adaptability to even lower temperatures.
With innovative technology and refined craftsmanship, Phohom New Material has successfully developed a variety of high-performance bimetallic connectors. These products, distinguished by their unique advantages, have found extensive applications across industries such as aluminum electrolysis, shipbuilding, and cryogenic engineering, providing robust technical support for industrial production and operations.
