Product Description

Superplastic sheet

Superplastic forming is a near-final forming process that can be used to prepare thin-walled integral components, effectively reducing structural weight, reducing the number of connectors, reducing costs, and improving the overall rigidity and reliability of the aircraft. As a domestic professional light alloy superplastic sheet production unit, the company uses its own advantages and adopts vacuum casting-thermomechanical heat treatment process to develop a series of high-performance magnesium alloy and aluminum alloy superplastic sheets, such as 2A97 superplastic sheets for use in astronaut helmets , 7475 superplastic sheet is used in spacecraft skins.

Application area
Superplastic alloys can be used to prepare integral components using inflatable or stamping forming techniques, and have been widely used in the aerospace field. They have been successfully applied to the hemispherical dome cover of the carrier rocket tank, the door of the fighter landing gear, the rocket and fighter fairing, and the aircraft partition doors, pillar covers of subway complex interior parts, etc.
