Lightweight high-strength snow shoveling sheet and preparation method thereof

The invention relates to the technical field of hard alloy, and discloses a lightweight high-strength snow shoveling sheet, which aims at solving the problems of low strength, high production difficulty, high cost and consumption of a large amount of scarce metal resources such as tungsten in the existing snow shoveling sheet alloy material, and comprises the following components: 10-15% of tungsten carbide, 20-25% of nickel powder, 5-10% of cobalt, 2-5% of molybdenum carbide, 0.05-1.5% of thorium dioxide, and the balance of aluminum powder. The balance is titanium carbonitride; the preparation method of the lightweight high-strength snow shoveling sheet comprises the following steps: S1, mixing and ball-milling the components according to the mass fraction to obtain a premix I; s2, drying the premix I, and removing the ball milling medium to obtain a mixture II; and S3, sintering the mixture II at a high temperature of 1500-1550 DEG C to obtain the snow shoveling sheet. According to the snow shoveling sheet,
