Spherical tungsten carbide powder
Feature:The spherical cast tungsten carbide powder produced by the induction plasma process has a high spheroidization rate (>95%), good sphericity and excellent performance. It can be used for plasma transfer arc surfacing (PTA), laser cladding, thermal spraying and other production.
Application field:Used in the production of cemented carbide. With spherical cast tungsten carbide as the hard phase, and molten nickel, cobalt and iron alloy as the binding phase coating, it can strengthen the surface of mechanical parts, improve wear resistance, and extend service life. It is used in mining, oil drilling, and engineering machinery. And aerospace and other fields have broad application prospects.

Product description

Feature

Tungsten carbide powder (WC) is the main raw material for the production of hard alloy, chemical formula WC. Full name, tungsten carbide powder is black hexagonal crystal, metallic luster, hardness and diamond similar, for electricity, heat good conductor. The melting point is 2870℃, the boiling point is 6000℃, and the relative density is 15.63(18℃). Tungsten carbide is insoluble in water, hydrochloric acid and sulfuric acid, and easily soluble in a mixture of nitric acid and hydrofluoric acid. Pure tungsten carbide is fragile, if a small amount of titanium, cobalt and other metals, can reduce brittleness. Tungsten carbide used as a cutting tool for steel is often added to titanium carbide, tantalum carbide, or a mixture of them to improve knock resistance. Tungsten carbide is chemically stable.

The spherical cast tungsten carbide powder produced by induction plasma process has high spherification rate (>95%), good sphericity and excellent performance, which can be used for plasma transfer arc surfacing (PTA), laser cladding, thermal spraying and so on.

 

Application field

Tungsten carbide powder is mainly used in the production of hard alloys. In tungsten carbide powder, carbon atoms embedded in the gap of tungsten metal lattice, does not destroy the original metal lattice, the formation of interstitial solid solution, so it is also called interstitial (or insert) compound. The coating with spherical cast tungsten carbide as hard phase and molten nickel, cobalt and iron alloy as bonding phase can strengthen the surface of mechanical parts, improve wear resistance and prolong service life. It has broad application prospects in mining, oil drilling, engineering machinery and aerospace fields.

 

Specification

0-20μm, 15-45μm, 15-53μm, 53-105μm, 53-150μm, 105-250μm Can be supplied according to customer requirements.

The appearance is black powder, high purity ≥99.9%, sphericity ≥95%, melting point is 2870℃, boiling point is 6000℃, density is 15.63g/cm³, loose density is greater than 7.0g/cm3, vibration density is greater than 7.5g /cm3, flow performance is less than 10.0s/50g, It has the characteristics of high hardness, low thermal expansion coefficient, high compressive strength, large elastic modulus and smooth surface. However, due to its high hardness, its machining performance is poor, so it is more suitable for application in 3D printing.

Spherical vanadium powder
The powder has good fluidity and high hardness. Adding to metal can increase the hardness and toughness, corrosion resistance, wear resistance and the ability to withstand punching loads.<br>It is used as an additive for fast neutron reactor jacket materials, superconducting materials and special alloys.
Spherical nickel-based alloy powder
Nickel-based alloys with other elements added. Nickel has good mechanical, physical and chemical properties. Adding appropriate elements can improve its oxidation resistance, corrosion resistance, high temperature strength and improve certain physical properties. Nickel-based superalloys have high strength, oxidation resistance, and gas corrosion resistance at high temperatures of 650-1000℃. They are the most widely used and highest-temperature-strength alloys among superalloys.<br> Used for 3D printing applications, powder metallurgy, injection molding, hot isostatic pressing, spraying, welding repair, etc.
Spherical cobalt chromium alloy powder
Used for 3D printing applications, powder metallurgy, injection molding, hot isostatic pressing, spraying, welding repair, etc. <br> Brand:CoCrMo, CoNiCrMo, CoCrMoW, Stellite alloys (Stellite 1, Stellite 3, Stellite 6, Stellite 12, Stellite 20, Stellite 21, Stellite 25, Stellite 31, Stellite 156, Stellite 157, Stellite 158, etc.).
Spherical iron powder
Pure metallic iron is silvery white, and iron powder is black. This is an optical problem because the surface area of iron powder is small and there is no fixed geometric shape. The crystal structure of iron block is geometrical, so the iron block absorbs part of visible light. The other part of the visible light is mirror-reflected and appears white; the light that the iron powder has not absorbed is diffusely reflected, and the visible light that can enter the human eye is small, so it is black.<br>
