---Excellent wear and corrosion resistance even at high temperature
up to 800℃
- Cobalt alloys have higher melting points than nickel (or iron)
alloys ,This gives them the ability to absorb stress to a higher
absolute temperature .
- Cobalt alloys give superior hot corrosion resistance to gas turbine
atmospheres , this is due to their high chromium content.
- Cobalt alloys show superior thermal fatigue resistance and
weldability over nickel alloys .
SYTOP cobalt base alloys is a range of cobalt-chromium-tungsten alloys with wear resistance, corrosion and high thermal resistance. It is
widely used in oil & gas, machinery, wood cutting, automotive,
paper and food processing industry etc.

Production process of our Cobalt Chrome Alloys .
1. Powder metallurgy process
a-- Better metallurgical structure, better strength
b-- Various types of automatic pressing machines from 3 tons to 630
tons. The ordered profiles can be very flexible.
2. Investment casting process
Different volume of furnaces, the order quantity can be very
flexible.
3. Machining
CNC, lathing, drilling, milling, grinding, wire cutting, polishing
Product Features
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.
