ZJYT PERP production line has successfully developed and produced the high-temperature alloy IN718, medical alloys and customized high-performance alloy powders such as T91, S30432, and high-entropy alloys for customers.
Superalloy powder GH99 alloy is an age-hardened nickel-based deformed superalloy. It is based on Ni, Cr, solid solution strengthening with W, Mo, Co, aging strengthening with Al, Ti, and grain boundary strengthening with B, Ce, and Mg. It can be used for a long time below 900 ℃. The alloy is mainly used for the combustion chamber, baffle, stiffeners and aircraft fixing parts of aero engine whose temperature does not exceed 1000 ℃.
ZJYT as a professional manufacturer of 3D printed metal powder materials in China, has a variety of powder production methods.
The morphology of GH99 alloy powder produced by ZJYT is shown in Figure 1. It has excellent sphericity, no satellite balls and hollow powder.
