Lightweight metal compound material

The invention discloses a lightweight metal compound material. The lightweight metal compound material is prepared from, by weight, 10-15 parts of titanium carbide, 20-45 parts of aluminum oxide, 1.5-3 parts of iron, 1-2.5 parts of molybdenum, 0.5-1 part of preservatives, 0.1-0.5 part of antifoaming agents and 20-35 parts of bonding agents, wherein the bonding agents can be one of resin, polymer or cellulose in a mixed mode; the bonding agent content of the metal mixture is no larger than 35 wt%; metal components are in the forms of colloid particles and at least one metal component is in a nanometer crystalline particle form; and as the bonding agents are mixed in the metal material, the hardness, the thermal expansion performance and the like of the metal material are effectively improved. The lightweight metal compound material has the beneficial effects that the production cost is reduced; the lightweight metal compound material has the properties of being low in weight, excellent in insulation performanc
