Studies have shown that the economic benefit of losing a pound of weight on a commercial aircraft is about $300, compared to about $30,000 on a spacecraft. However, there are still some fatal bottlenecks in current applications. For example, ordinary magnesium alloys are flammable, and burning magnesium alloys and titanium alloys will release a large amount of heat, which will lead to the extended combustion of large surfaces, which significantly restricts their application in the aerospace field. Therefore, in order to dispel people's scruples about "magnesium fire" and "titanium fire" and expand the application of light alloys such as magnesium and titanium in the aerospace field, it is necessary to comprehensively evaluate the combustion properties of these metals.

In addition, the existing simple devices are prone to produce smoke to pollute the environment during the test, and there are safety risks when testing larger samples.
