The invention discloses a marine metal composite plate and a preparation method thereof, and belongs to the technical field of metal materials. According to the marine metal composite plate, the yield strength is 390-450 Mpa, the tensile strength is 490-560 Mpa, the shear strength is larger than 200 Mpa, the interlayer bonding rate is 100%, the thickness of a bonding layer is 1.8-2.6 microns, a composite interface contains trace FeTi and Fe2Ti, no TiC brittle phase exists, cracking is avoided when the metal composite plate is bent inwards and outwards by 180 degrees, and the corrosion performance is qualified. The metal composite plate prepared through the method is high in interlayer bonding strength and high in yield, has the advantages of being resistant to corrosion, light in weight, high in strength, resistant to high temperature impact and the like, and is suitable for ship manufacturing and other large-scale industrial manufacturing fields.
