The products supplied by EHMAT for the aerospace industry are mainly for the capillary conveying pipes of special fluids for aero engines and space rocket satellites and alloy pipe fittings for precision instruments. It also supplies alloy profiles. The high-temperature alloy capillaries supplied by EHMAT (such as GH41691*0.05*900mm) have been at the leading level in the industry.

The aerospace industry is a concentrated expression of the country’s comprehensive national strength, industrial foundation, and technological level. The aerospace equipment has a complex structure and uses a wide range of materials. Working under conditions, in addition to relying on optimized structural design, it also depends on the excellent characteristics and functions of the material.

Superalloys have been used in aeroengines since their inception. In modern aeroengines, the amount of superalloy materials accounts for 40% to 60% of the total weight of the engine. They are mainly used in four hot-end components: combustion chamber, guide, and turbine blades. And turbine discs, in addition, are also used for parts such as casings, rings, afterburners and tail nozzles.

Representative high-temperature alloy grades are:

Solid solution strengthening nickel-based alloy: GH2132GH2507, GH3030, GH3039, GH3028, GH3128, etc.

Age-hardening nickel-based alloys: GH4033, GH4037, GH4043, GH4049, GH4133, GH4169, GH4145, etc.

Foreign superalloys are called inconel series, incoloy series, Hastelloy series (such as GH4169 corresponding to Inconel718, etc.)
