Copper based alloy powder’s coating is densification, be able to bear tiny abrasion and gas etching, with good properties of abrasion resistance and lubrication, easy to cut coating, will reach to the best smooth finish and the higher conductivity.
Main Purpose :
chemical fiber spinning melt new filter material ,water treatment plants ,precision physical filteration materials,stainless steel sintered filter cartridge and powder metallurgy materials .
Introduction of stainless steel sand:
In order to increase the production efficiency and better fiber quality, chemical fiber mills nowadays are using irregular shaped stainless steel powder as filter medium in the fiber making process (to replace with silica sand and aluminum oxide).
Characteristics of Stainless Steel Filter Powder:
1.Inert to Polymers
High-chromium alloy stainless steel powder is inert to all polymers due to the protective chromium oxide coated on the particle surface.
2.High Porosity Rate
The porosity rate of our powder is as high as 70% - 80%, which can easily capture more foreign bodies, decrease the pressure rising rate, and increase the pack life of spinneret.
3.High Shearing Ability
Our stainless steel powder has very sharp, strong, and irregular edges, which is very good for filtering, shearing and stripping fine micro gels from melt polymer. As Silica sand doesn?t come with such edges, fiber produced with our powder is stronger, and better in quality.
4.High Thermal Conductivity
Lots of heat will be generated when polymer is passing through the spin pack and will be accumulated at the area. As stainless steel powder has better heat conductivity (than silica sand for 4 times more), it can effectively remove the heat for better temperature control and it is a perfect solution for high-speed spinning.
5.Resistance to Compaction
Although both of stainless steel powder and silica sand have good resistance to compaction, stainless steel powder is good at steel powder can extend the pack life for 2 -3 times than silica sand, and that makes our powder the better filter media for the spinneret.
6.Precise Size Distribution
Powder is made by water atomization, which can produces stable quality with precise size distribution.

,STELLITE COBALT BASED ALLOYS, consist of complex carbides in an alloy matrix. They are resistant, to wear, galling, and corrosion and retain these properties at high, temperatures. Their exceptional wear resistance is due mainly, to the unique inherent characteristics of the hard carbide phase, dispersed in a CoCr alloy matrix.,
STELLITEtm 6 is the most widely used of the wear resistant, cobalt-based alloys and exhibits good all-round performance., It is regarded as the industry standard for general-purpose wear, resistance applications, has excellent resistance to many forms, of mechanical and chemical degradation over a wide temperature, range, and retains a reasonable level of hardness up to 500°C, (930°F). It also has good resistance to impact and cavitation, erosion. Stellitetm 6 is ideally suited to a variety of hardfacing, processes and can be turned with carbide tooling. Examples, include valve seats and gates, pump shafts and bearings, erosion, shields, and rolling couples. It is often used self-mated.
