Stabilization of Copper Cobalt Alloy in the Melting Temperature Range

In China, mainly detailed research for high temperature alloys and completely Copper Cobalt Alloy . Other high temperature different alloys are not strengthened with bond ordered deposits on high-temperature alloy Cobalt-Chromium Alloy, but small amount of carbide distribution is enhanced by FCC austenite solid solution matrix and matrix composition. Casting a Cobalt-Chromium Alloy superalloy depends primarily on silicon carbide strengthening. Pure cobalt crystal is less than 417 ° C. Crystal structure C, FCC of hexagonal close packed (HCP) is converted at higher temperature. To avoid Cobalt-Chromium Alloy transitions in such superalloys, in fact, all of the nickel alloy Cobalt-Chromium Alloy section, melting point occurs during use, so as to stabilize the temperature range of the tissue at room temperature. It is possible to have it because there is an upper high chromium containing alloy, such as alloy, which has been shown that the Cobalt-Chromium Alloy-temperature relationship with plane fracture stress has an excellent high temperature other than high temperature corrosion resistance at 1000 ° C .

Cobalt-base superalloys generally have low and moderate high temperature strength (nickel-based alloys of only 50 to 75 percent) at temperatures above 980 ° C lack coherent reinforcing phase, but high strength, good heat Fatigue and corrosion resistance Wear resistance performance, and with excellent weldability. Suitable for manufacturing aircraft jet engines, industrial gas turbines, marine gas turbine blades and nozzle guide vanes and diesel engine nozzles.

Cobaltalloys that from cobaltalloy.net 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.

---Excellent wear and corrosion resistance even at high temperature up to 800℃

Shenyang Top New Material Co.,Ltd cobalt base alloys is a range of Cobalt Chromium Alloy 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.
