What`s the Feasures of Sytop Stellite Alloy 6 ?

1. High temperature resistance

The strength keeps stable up to 800℃ and it can even momentarily used at 1200℃.

2. Wear resistance

Due mainly to the unique inherent characteristics of the hard carbide phase dispersed in a

CoCr alloy matrix, it has exceptional wear and galling resistance.

3. Corrosion resistance

This exellent and lovely property allows this kind of material parts to be used in oil&gas, slurry, acid liquid and any other mediums.

During the past developed, we have got the support and care from customers and relative persons. That made our Stellite Alloy 3 company grown up very quickly. We sincerely hope you can continue to support us in future, provide good advises for our developing.

Stellite Alloy Using in Textile Industry Widely

As a matter of fact, the Viscose Staple Rayon Fiber Cutter Stellite Alloy Blade is one of the cobalt alloys. With special chemical composition, it is widely used in textile industry. We control the core technology to produce this kind of cutter blade through powder metallurgy. Corrosion resistance and wear resistance of this blade are better than other material. We have various specifications of stellite alloy blade which can be provided for customers according to their requirements.

It is known to us that stellite alloy blades are produced by a range of different processes, including wrought or hot forging, hard-faced deposit, powder metal, and finally, casting. It’s more difficult to machine and grind than a steel blade. Therefore, high-performance processing equipment and specialized machining tools are required. As usual, it is machined by grinding instead of cutting.

Sytop Stellite Alloy 3 applies to the production line which produces viscose staple fiber and we have built cooperation with several big manufacturers around the World. The cutter blades are consumable products and life-span is about half a month for each blade. we are more flexible and superior sales service. What’s more, free samples for customers that we supply can be tested. Our factory guarantees the high quality.

Sytop Cobaltalloy has been committed to researching and developing the Stellite Alloy 4 for more than 20 years. We can produce high quality cutter blade with powder metallurgy and control the cost to give a favorable price to our customers.

With excellent equipment, strong design capability, and a large production team, Sytop Cobaltalloy strives to achieve international standards and looks forward to growing together with all customers for a mutual benefit and a better tomorrow!

Sytop Stellite 12 (Stellite Alloy 12)

Stellite Alloy consist of complex carbides in an alloy matrix. Their exceptional wear resistance is due mainly to the unique inherent characteristics of the hard carbide phase dispersed in a CoCr alloy matrix.

Stellite Alloy 12 Saw tips are made of Stellite alloy in grade Co12,so the following information is all about Co12.

Stellite 12 can be considered as an intermediate alloy between Stellite 6 and Stellite 1. It contains a higher proportion of hard brittle carbides than Stellite6 and has enhanced resistance to low angle erosion, wear and severe sliding wear while maintaining reasonable impact and cavitation resistance. Stellite 12 is typically used to self-fit or run Stellite 6 or Stellite 1. Higher tungsten content provides better high temperature performance than Stellite 6, and can be used at temperatures up to about 700˚C.

Stellite 12 is typically used in cutting tools that need to withstand wear, heat and corrosion. Examples include industrial knives for cutting carpets, plastics, paper and synthetic fibers; and see the skills of the wood industry. It is also used in the beverage industry’s control panels, pump blades, bearing bushings and narrow neck glass mold plungers; and for surface hardening of engine valves, pinch rolls and rotor blade edges in the metalworking industry. Corrosion resistance The typical electrode potential in seawater at room temperature is approximately -0.3 V (SCE). Like stainless steel, Stellite 12 is primarily corroded by pitting mechanisms, rather than by general mass loss in seawater and chloride solutions.

We can manufacture Stellite Alloy 3 according to your drawings and demands. We can produce rectangular, triangle, specical-shaped saw tips .and we also can manufacture saw tips of U.S.A. standard and Europe standard.

The Difference Between Cobalt Alloy And Nickel Alloy

The Difference Between Cobalt Alloy And Nickel Alloy.

1.Thermal stability

One of the important reasons why cobalt alloys are used as aviation material is its excellent thermal stability. Cobalt alloys have a high melting point and thermal conductivity and less thermal expansion after heating. It can be seen from this that cobalt alloys have advantages in thermal stability.

Compared with cobalt alloys, nickel alloys have a higher strength but more brittle. It is easier to be broken on occasions of impact. When the temperature rises to 800℃ (the operating temperature of some engines), nickel alloys can’t be used, while cobalt alloys retain strong.


The stiffness means the ability to resist deformation. Nickel alloys have a lower stiffness than cobalt alloys in various temperature. With the temperatures above 700℃, the properties of nickel alloys are completely destroyed.

3.Oxidation resistance

Cobalt Chromium Alloy has superior resistance to high-temperature oxidation. Cobalt alloys have excellent resistance to high-temperature oxidation and can be used in the case of 800℃.

4.Corrosion Resistance

Corrosion resistance of both alloys was tested as follows. With 4 m/s rate, combustion air containing 5-5 or 5-6 sea salt, NO. 2 fuel oil (0.3% ~ 0.45% sulfur ), and air – oil ratio for 30:1, the sample was rotated cooled from 800℃ to 260 ℃with cold air every an hour. This dynamic hot corrosion test after the cycle test for 200 hours in the combustion apparatus shows that metal loss portion of the cobalt alloys is significantly lower than that of nickel alloys.

In conclusion, the performance of Cobalt Chrome Alloy is much better than nickel alloys, ensuring the use and life of the products. Cobalt alloys have the following advantages: Above all, the hardness of the cobalt alloys are much lower than that of turbine rotors, which makes it safer. In addition, cobalt alloys have a higher melting point and thermal conductivity, and the amount of thermal expansion after heating is small. It has an advantage in thermal stability. What’s more, the strength of the cobalt alloys are slightly lower at normal temperature, but the elongation is higher. Last, cobalt alloys have excellent resistance to high-temperature oxidation and can be continuously used in an environment of about 800℃. The corrosion resistance of cobalt alloys is much better than that of nickel alloys as well.
