These two materials are used in different fields, and how to use them correctly can give full play to the greatest advantages of the product. Next, we briefly introduce the characteristics of the two.
Cunifer is a type of alloy. The main components are nickel, copper and iron, and also contain one or several other impurity elements. The main role of nickel and copper in stainless steel is that it changes the crystal structure of the steel.
One major reason for adding both factors to stainless steel is the formation of an austenitic crystal structure that significantly improves the properties of stainless steel strength, corrosion resistance, hardness, resistance and thermopower, and reduces the resistivity temperature coefficient, so nickel is also known as the austenitic forming element. Nickel and copper with a certain proportion of the content can improve the tensile strength, hardness, impact toughness, yield point and deformation capacity of low-carbon structural steel.For long-term use at 1000 temperature. Because this steel has a suitable ratio of tensile strength to quality, it is very suitable for castings in the automobile, locomotive and machine manufacturing industries.
As a result, copper-nickel ferroalloy tubes are also used as brake tubes, but now these tubes are increasingly replaced by PTFE tubes.Because the cost of this material is high, heavy weight, and the pipe is not flexible, need to process the tube to be finalized, must be used by the machine, so as to be successfully assembled during operation.
SS PTFE hoses:
PTFE hose is a special hose made by drying, high temperature, sintering and shaping. Polytetrafluoroethylene (PTFE) has excellent chemical stability, it prevents corrosion and aging, resists all strong acid, alkali and oxidants, and does not act with various organic solvents, very suitable for high purity chemicals.In addition, PTFE tubes are also resistant to high pressure and can be applied to-65℃ ~260℃ for a long time, with little mechanical performance change after treatment for 1000h.
It has excellent electrical insulation properties, PTFE is highly non-polar material with excellent dielectric, great resistance and dielectric constant of about 2.0 and is the smallest of all electrical insulating materials.Moreover, PTFE has a very low friction factor, which is a good friction reduction, self-lubricating material, whose static friction coefficient is less than the dynamic friction coefficient, so making bearings has the advantages of small starting resistance and smooth operation.
In addition to the above characteristics, the reason why the PTFE hose is widely used is still cost-effective, light, good bending and other characteristics.
