CLAD PLATES
Clad Plates
Our Clad Metal Plates are composite metal materials formed by metallurgically bonding one or more layers of precious metal corrosion-resistant alloys with a more cost-effective high-strength substrate through explosive cladding or roll bonding processes. The clad materials typically include titanium, zirconium, tantalum, silver, copper, aluminum, nickel-based alloys, stainless steel, and others, while the substrates are generally high-strength carbon steel, stainless steel, aluminum, and similar materials.
As a new, high-performance, and cost-effective material, clad metal plates combine the characteristics of both the base and clad materials. They typically exhibit a high strength-to-weight ratio, excellent high-temperature resistance, and superior corrosion resistance. The performance of these plates depends not only on the properties of the base and clad materials but also on their composition and distribution. Compared to single homogeneous materials, clad plates offer superior overall performance, better workability, and a wider range of metal combinations, significantly reducing material procurement costs for customers.
Clad metal plates feature a high bonding strength between the clad material and the substrate, with a bonding rate close to 100%. They also have excellent welding and processing performance, while costing only 30% to 50% of pure single-material alternatives. These plates are primarily used in process equipment and pressure vessels in the chemical industry, methanol fuel tanks in shipbuilding, as well as in the power, marine engineering, paper, environmental protection, and light industries.
Depending on the manufacturing method, our company can produce both explosive clad plates and roll-bonded clad plates.
Roll Bonding Process
Roll Bonding Process is a technique where a substrate is bonded with one or more thinner cladding materials (in a “hamburger” configuration) through high-temperature, high-pressure rolling, resulting in a uniform and strong metallurgical bond between the metals. The process offers the following advantages:
Below is roll bonding production process:
Explosive Bonding Process
Explosive Bonding Process uses explosives as an energy source to cause a high-speed oblique collision between the metal surfaces being bonded. This process creates a thin transition layer on the surface with characteristics of plastic deformation, melting, diffusion, and wave-like patterns, resulting in a strong metallurgical bond between the metals. The Explosive Roll Bonding Process involves initially welding the materials through explosive bonding, followed by hot rolling, cold rolling, or a combination of hot and cold rolling. This method offers the following advantages:
