20-12-2020· CNPC POWDER is one of the top metal powder suppliers in the world, exporting their prodcuts to over 40 different countries. The main products include Iron and Iron Alloy Powder,Copper and Copper Alloy Powders and Nickel Powder and they also supply other metal powders.
Powder production. Virtually all iron powders for PM structural part production are manufactured using either the sponge iron process or water atomisation. Non ferrous metal powders used for other PM applications can be produced via a number of methods. Mixing of powders
Stainless steels and super alloy powders possess excellent properties for hot polymer filtration. They do not react chemically with the polymers and they are strong enough to minimize compaction during filtration. The powder processing – high-pressure water atomization – results in extremely irregular shaped particles.

27-08-2018· Productivity: Iron powder for ss (stainless steel) cutting process reduces cutting time inturn effecting in increased productivity with the same work force and time.Results have shown rise in productivity upto 60%. In manual operation results vary. Efficiency: Iron powder cutting process helps in increasing efficiency of the work force resulting in higher productivity and benefit the industry ...
Stainless steel can also be cut using flame cutting, which involves a flame-fired torch using oxygen and propane in conjunction with iron powder. This method is clean and fast. Another cutting method is known as plasma jet cutting, in which an ionized gas column in conjunction with an electric arc through a small orifice makes the cut.
The selection of materials available for PM processing covers a very extensive range of materials. A complete enumeration is too lengthy for the present discussion, but an illustrative listing of materials in typical components made from metal powder is provided below. Iron/steel. Stainless steel. Copper.
3. Atomisation Processes. Atomisation is the breakup of a liquid into a fine spray. If done on a molten material, the resulting spray commonly freezes into powder. There are many ways to atomise metal ( 8 ), but for the modern manufacturing methods discussed …
Material Efficiency: One of the powdered metallurgy advantages of the PM process cost-wise is that the finished powdered product uses virtually of the PM consumed. This eliminates the waste found in the stamping, fineblanking, or machining processes when …
25-05-2016· The stainless steel can be straight sheared with guillotine knives, circle sheared using circular knives, sawed using high-speed blades, or blanked with punches and dies. Other methods include flame cutting, which uses a flame-fired torch powered with oxygen, propane, and iron powder, or Plasma Jet cutting which uses an ionized gas column in conjunction with an electric arc to cut the metal.

Non-corrosive and easy to clean, stainless steel is revered both for its strength and its appearance. A go-to material in transportation, consumer goods, food production, construction, and a variety of other industries, stainless steel plates and tubes are popular work materials for drilling and tapping applications. While a common material, drilling and tapping stainless
07-08-2021· Metal plating can improve a product's durability, corrosion resistance, surface friction, and exterior appearance. In the case of galvanized metal, the zinc plating serves as a sacial anode, itself corroding while protecting the integrity of the underlying substrate.
This pressure depends on the properties of metal powder and binders. For soft powder compacting pressure is about 100 – 350 MPa. For steel, iron, etc. the pressure is between 400 – 700 MPa. 4. Sintering: The green compact, produced by compressing, is not very strong and can…
24-05-2021· You can protect your stainless steel objects from rust and scratches with a few cleaners. If you need to get rid of tough stains, use rubbing alcohol or a solution of equal parts water and vinegar, and clean it with a sponge or microfiber cloth.
