Provides high strength and heat resistance properties due to high aluminum content and silicon doping. The maximum operating temperature is 480 ° C The alloy is thermally stable, plastic, crack resistant. Double and isothermal annealing provides an optimal combination of properties; the β-phase content in the annealed alloy is about 10%.
Application: Mainly used in GTE details (discs, low pressure compressor blades, fan mounting parts).
