What are the properties of metal fibers
Upload Time:
2022-06-10
Metal fibers generally reach the micron level. For example, stainless steel fibers generally have a diameter of about 10 μm, and the average diameter of thin stainless steel fibers supplied in the market is 4 μm. Metal fibers have good mechanical properties, not only high breaking strength and tensile modulus, but also bending resistance and good toughness; they have good electrical conductivity and can prevent static electricity, such as tungsten fibers used as filaments of incandescent light bulbs At the same time, it is also an important material for preventing electromagnetic radiation and conducting and electrical signal transmission; it has high temperature resistance; stainless steel fiber, gold fiber, nickel fiber, etc. also have good chemical corrosion resistance, and it is not easy to oxidize in the air.

Metal fibers have the following characteristics: (1) Metal fibers can operate at temperatures of 500-590°C (930-1100°C), and may be used in more complex systems in the future. (2) Metal fibers are better than ceramic filter media in terms of high pressure drop, purification capacity and stability at high temperature. (3) The metal fiber has an irregular section and a conventional surface area, which makes it have a very large specific surface area.
