The titanium cube meets the requirements of lightweight and high reliability in the aviation field through precision machining and strict process control. Its core advantages are:

Specific strength: (strength/density ratio) is 1.3 times that of steel and 1.6 times that of aluminum alloy;

Corrosion resistance: The service life is more than 3 times that of stainless steel in a humid/salt spray environment;

Process adaptability: Complex structure integrated molding can be achieved through additive manufacturing (such as EBM).
