Cobalt oxide (Co203) is an expensive cobalt oxide with a theoretical cobalt content of 71.06%, an oxygen content of 28.94%, and a density of 6.079/cm3. It is a black amorphous powder that generates cobalt oxide (Co304) after heating. Cobalt oxide is an unstable compound and cannot be freed. The cobalt oxide commonly referred to actually still contains a certain amount of cobalt tetraoxide. Co203 is only stable in a hydrated state. This hydrate will dehydrate and transform into the intermediate oxide cobalt tetraoxide (Co304) at 265�°C. Cobalt oxide is reduced to cobalt tetraoxide (Co304) by H2 at 125�°C, reduced to CoO at 200�°C, and reduced to cobalt metal at 250�°C. Cobalt oxide is insoluble in water. After dissolving in water, it decomposes into hydrates when it encounters water. It is insoluble in water, but soluble in acid and forms corresponding salts.
Nickel is a hard, ductile and ferromagnetic metal that is highly polished and resistant to corrosion. Nickel is a ferrophilic element. The core is mainly composed of iron and nickel elements. In the crust, iron-mafic rocks contain more nickel than silico-alumina rocks. For example, peridotite contains 1,000 times more nickel than granite, and gabbro contains 80 times more nickel than granite. On October 27, 2017, the World Health Organization's International Agency for Research on Cancer released the preliminary list of carcinogens for reference. Nickel compounds are in the list of carcinogens, metal cobalt, metal nickel and 66-67% nickel, 13-16% nickel. Chromium and 7% iron alloy powders for implantation of foreign bodies in vivo, nickel metal and nickel alloys are on the list of Class 2B carcinogens. Niclkel powder is mainly used in atomic energy industry, conductive materials, battery electrode materials, chemical catalysts, hard surface spray welding, special welding rods, porous filter materials, magnetic materials, contact materials, Diamond tools, automobile manufacturing, cemented carbide, high-temperature high-strength alloys and other powder metallurgy fields.

English name: Vanadium Nitrogen Alloy Molecular formula: VN12VN14 VN16 CAS NO.: 24646-85-3 Boiling point:2360 Shape: small lump Grade Standard: Industrial Grade Application: Vanadium nitrogen alloy can be used in structural steel, tool steel, pipe steel, steel bar and cast iron. The application of V-N alloy in high strength low alloy steel can effectively carry out v and N microalloying at the same time, promote the precipitation of carbon, V and N compounds in the steel, and play a more effective role in precipitation strengthening and grain refinement. The addition of VN to steel can improve the comprehensive mechanical properties of steel, such as strength, toughness, ductility and thermal fatigue resistance, and make the steel have good weldability. The yield of vanadium and nitrogen is stable and the fluctuation of steel properties is reduced. It is easy to use and less loss. High strength moisture-proof packaging, can be directly into the furnace. Packing: Big Bag
English name: Vanadium Pentoxide (Flake) Molecular formula: V2O5 CAS NO.:1314-62-1 Density:3.357g/cm3 Melting point:690 Boiling point:1750 Aqueous solubility:1g/125mL Appearance : gray black flake Application: Vanadium flakes are mainly used in the iron and steel industry. By refining the structure and grains of steel, the grain coarsening temperature is increased, thereby increasing the strength, toughness and wear resistance of the steel. In addition, vanadium flakes are excellent in titanium alloy Improved effect, used as an additive in the aerospace field.
English name: Ferro Vanadium Molecular formula: FeV80 CAS NO.: 12604-58-9 Boiling point:3337 Melting Point:1887 Shape: small lump Purity:FeV50-A/B/C, FeV80-A/B/C Grade Standard: Industrial Grade Application: Ferrous vanadium is a ferroalloy composed of vanadium and iron, which is mainly used as an alloy additive in steelmaking. The vanadium in ferrovanadium can improve the strength, toughness, ductility and heat resistance of steel, and improve the cutting performance of steel.

Cast Iron and Ductile Iron tube and fittings PL739 Cast Iron and Ductile Iron tube and fittings can be offered by our comapny to meet different engineering needs. The difference between ductile iron and gray iron 1. Different chemical composition Nodular cast iron contains nodular graphite, which can improve its toughness and strength, while reducing brittleness. Gray cast iron contains a lot of carbon, so that its hardness and wear resistance is high, but the toughness is poor. 2. Different organizational structures The structure of nodular cast iron contains nodular and ferrite, and the distribution of nodular is uniform. While the structure of gray cast iron is mainly ferrite and pearlite, and the distribution of pearlite is uneven. 3. Different performance Ductile iron has high strength and toughness, and has good corrosion resistance. It is uitable for the manufacture of high load and high pressure parts. The hardness and wear resistance of gray cast iron are high. It is suitable for the manufacture of friction and wear parts. Application field Cast iron : because of its low strength and good vibration resistance. It is often used in the production of parts under compressive stress, such as box, base, etc. Ductile iron : because of its high strength and good toughness. It is often used in the manufacture of parts requiring high strength and toughness, such as crankshaft, connecting rod and so on.
