Titanium coils
Because of the poor thermal conductivity of pure titanium, the emulsion with good lubrication effect and excellent cooling performance is required in the rolling process, and the rolling speed should not be too fast, in order to prevent the high temperature of pure titanium and cause the phenomenon of “sticking roller”, and “sticking roller” resulting in rough surface of titanium and poor quality. The residual water and oil on the surface of the titanium strip decompose during the annealing process, which affects the partial pressure of oxygen in the furnace and causes the decomposition reaction to go in the opposite direction, forming oxidation on the surface of the titanium strip and affecting the annealing quality. Because titanium strip annealing before full degreasing cleaning and drying plate surface. The degreasing speed of titanium strip is generally 20m/min, and the speed is adjusted according to the surface quality of the titanium strip after degreasing. Straightening is to ensure the flatness of the product plate.

Manufacturing process
Cold rolled titanium coil due to different production processes (or finished product surface) generally divided into cold rolled pickling surface titanium coil and cold rolled glossy titanium coil.
The manufacturing process of cold rolled pickling surface titanium coil of XRUN is: sponge titanium — melting — forging — hot rolling — heat treatment — shot blasting — hot rolled pickling white roll — cold rolling — heat treatment — shot blasting — pickling — edge cutting — inspection — cold rolled pickling white roll — packing and storage.
production process
In the production process, because the product is rolled twice, the oxide scale will be produced. Two heat treatment and shot blasting pickling are the treatment of the oxide scale on the surface of the product, so as to better ensure the quality of the product. Cold rolled pickling surface titanium coil is generally used in aerospace, industry and marine engineering. Compared with the former, cold rolled glossy titanium coil is more widely used. Similarly, there are two more steps in the production process of cold rolled titanium coil with glossy surface than pickling surface: degreasing annealing and straightening.

The titanium coil is mainly used as a container for heating and cooling. titanium coil fixation is divided into two kinds of detachable and non-detachable, This depends on the medium's corrosion of the titanium coil. But mainly based on removable type, convenient maintenance and cleaning of titanium coil.
Application features
Excellent corrosion resistance in many media
Smooth surface, clean layer
Low density, high strength and light weight
Low density, high specific strength
The density of metallic titanium is 4.51g/cm3, which is higher than that of aluminum and lower than that of steel, copper, and nickel, but the specific strength is at the top of the metal.
Corrosion resistance
Titanium is a very active metal with a low equilibrium potential and a high tendency for thermodynamic corrosion in media. Namun, titanium is actually very stable in many media. For example, titanium is resistant to corrosion in media such as oxidative, neutral and weak reducibility. This is because titanium and oxygen have a great affinity. In air or oxygen-containing medium, a dense, strong and inert oxide film is formed on the surface of titanium to protect the titanium matrix from corrosion. Even if it is due to mechanical wear, it will quickly heal or regenerate. This shows that titanium is a metal with a strong tendency to passivation. The oxide film of titanium below the temperature of 315°C always maintains this characteristic.
In order to improve the corrosion resistance of titanium, surface treatment technologies such as oxidation, electroplating, plasma spraying, ion nitriding, ion implantation, and laser processing have been studied. Titanium oxide film played a role in enhancing protection and obtaining desired corrosion resistance. A series of corrosion-resistant titanium alloys such as titanium-molybdenum, titanium-palladium, and titanium-molybdenum-nickel have been developed to meet the needs of metal materials in the production of sulfuric acid, hydrochloric acid, methylamine solution, high-temperature wet chlorine, and high-temperature chloride. Titanium-32-molybdenum alloys are used in titanium castings. Titanium-0.3 molybdenum-0.8 nickel alloys are used in environments where crevice corrosion or pitting corrosion frequently occurs. Titanium-0.2palladium alloys were used locally in titanium equipment, and good results were obtained.
Good heat resistance
The new titanium alloy can be used long-term at 600 °C or higher.
Low temperature resistance
Low temperature titanium alloy represented by titanium alloys TA7 (Ti-5Al-2.5Sn), TC4 (Ti-6Al-4V) and Ti-2.5Zr-1.5Mo, etc.Its strength increases with decreasing temperature, but the plasticity changes are not large.It maintains good ductility and toughness at -196-253°C and avoids cold brittleness. It is an ideal material for cryogenic vessels and tanks.
Strong anti-damping performance
After metal titanium is subjected to mechanical vibration and electric vibration, its own vibration decay time is the longest compared with steel and copper metal. The use of this property of titanium can be used as a tuning fork, a medical ultrasonic vibrator vibration element, and an advanced sound speaker vibration film.
Non-magnetic, non-toxic
Titanium is a non-magnetic metal, it will not be magnetized in a large magnetic field, non-toxic and has good compatibility with human tissues and blood, so it is used by the medical community.
Tensile strength is close to its yield strength
This property of titanium shows that the yield strength ratio (tensile strength/yield strength) is high, indicating that the metal titanium material is poor in plastic deformation during forming. Since the ratio of the yield limit of titanium to the elastic modulus is large, the resilience of titanium when molded is large.
Good heat transfer performance
Although the thermal conductivity of titanium metal is lower than that of carbon steel and copper, due to the excellent corrosion resistance of titanium, the wall thickness can be greatly reduced, and the heat exchange mode between the surface and steam is droplet condensation, which reduces the thermal group. Titanium surface without scaling can also reduce the thermal resistance, so that the heat transfer performance of titanium is significantly improved.
Low modulus of elasticity
The modulus of elasticity of titanium is 106.4 GMPa at room temperature, which is only 57% of steel.
Suction performance
Titanium is a chemically very reactive metal that reacts with many elements and compounds at high temperatures. Titanium inhalation mainly refers to reaction with carbon, hydrogen, nitrogen, and oxygen at high temperatures.
Materials
Can be divided into: TA1 [Content 99,6], TA2 [Content 99,5], TA9 [Titanium Palladium Alloy], TA10 [Ti-Mo-Ni alloy

Copper Sheet
Copper sheet is a very workable and malleable form of metal, high in electrical and thermal conductivity, and provides excellent corrosion resistance. A beautiful and versatile metal, copper has been utilized for thousands of years. Historically, it served as a favorite choice in making tools, vessels, and sculptures. Copper is also known for its beautiful patinas. When exposed, unsealed, to an outdoor environment, copper begins to oxidize. This exposure creates beautiful color variations in the form of a patina. The coloring of the patina will change and develop character over time while serving to protect the metal from deterioration. People will also create a patina quickly with the use of chemical mixtures that speed the process up and allow a patina to develop without outdoor exposure. Copper sheets can also be hammered, tooled, or embossed for added texture and decorative or functional appeal and come in many thicknesses from very thin copper foil to thick copper plate. It also comes in many alloys that blend other metals with copper. At Grand Copper, we sell pure copper -C110 (other alloys and tempers available upon request). This high purity provides the premium quality needed for projects and applications in a wide range of industries and uses. We take pride in providing the best material. Our high-quality, affordable material and friendly, first-rate customer service have made us a leader in the industry for over a decade.
