Metal composite material is a material made of two or more chemically different combination of the starting monomer material, or is reinforced by the base material and the raw material and the obtained composite disposed new material. Compared with the monomer material, the composite material has a function of many things in common, the mechanical advantage is its primary function, the function of the physical or chemical function satisfactorily specific requirements or to reduce the cost function, which is the starting monomer material can not be achieved.
Currently there are many types of titanium composite materials, such as titanium clad steel plate, titanium package copper rod, copper and titanium steel, titanium and other transition joints, titanium composite materials can not only satisfied the needs of users to use, and the price is lower than that of pure titanium or titanium alloy, welcomed by the mall. Such as titanium steel composite panels, both with the strength of steel, but also has the function of corrosion-resistant titanium, widely used in the metallurgical and chemical equipment production.
Titanium copper composite rod copper rod known as titanium package. Electrolytic copper metal anode is made of titanium composite rod support, its role has three points: First, to support the anode; two conductive; Third corrosion. For the satisfaction of these needs, the use of the corrosion resistance of titanium and copper conductivity, the contact with both. Composite bar intermediate copper, outsourcing a layer of titanium, a square lantern-shaped cross-section two, completely satisfied with the use of demand. Titanium copper composite billet in the extrusion process by strong pressure, metallurgy contact form two metal interface, waveform interface is the best way to contact the two metals, copper and titanium composite rod enhance contact reliability, resistivity small, conductive function better. Foreign developed a titanium-copper composite pipe, the copper outer titanium, its strength lies in saving copper materials, corrosion function better.
Blasting welded transition joints with high strength and low contact resistance of the contact interface, use can enhance production, improve efficiency and energy conservation in the industrial sector. Current research and development of titanium copper, titanium steel, titanium steel, aluminum stainless steel, aluminum titanium stainless steel, aluminum and copper steel, copper and other transition joints. Whether the plate is still a tubular metal transition joints, can be achieved by an appropriate scale of flat parts, but usually there is a transition joints used in the stress, there is thermal shock and high current site, which has a relatively Gao demand strength and excellent links conductivity function. Selection of improved flat blasting composite technology can be obtained with high contact strength, low interface resistance bimetallic transition joints and three kinds of metal materials.
