The application of Cobalt base alloy powders in the valve industry.

Automotive intake and exhaust valves are crucial components of the engine, and their quality directly affects major performance indicators such as engine power and

fuel consumption. It has a significant impact on the reliability of the engine. The working environment of exhaust valves is particularly harsh, as they not only bear

high-speed and impact loads but also have to operate stably under conditions of high temperature, corrosion, and erosion. The working conditions, especially for the

valve cone surface, are extremely harsh.

With the development and popularization of automotive turbocharging technology, engine fuel consumption has decreased, and emissions have been reduced.

However, the surface temperature of the engine combustion chamber has increased, and the ignition delay period has shortened. This means that the exhaust valve has

to withstand tremendous explosive force and higher temperatures.

Cobalt-based self-fusing alloy powder, due to its excellent properties such as heat resistance, thermal shock resistance, wear resistance, corrosion resistance, creep

resistance, and erosion resistance, plays an increasingly important role in the automotive valve industry.

Shenyang Rare Metal Research Institute, as a leading producer of advanced cobalt-based alloy powder in China, has been committed to the research and development

of materials suitable for the surfacing of valve cone surfaces and valve stem tops in the valve industry.

Our company now provides the following materials：
