The invention discloses a C-modified Be-Ni-RE high-strength heat-resisting aluminum alloy material. The agent comprises the following components in percentage by weight: 1.0-10.0 percent of Cu, 0.05-1.5 percent of Mn, 0.01-0.5 percent of Cd, 0.01-0.5 percent of Ti, 0.0001-0.15 percent of C, 0.01-1.0 percent of Zr, 0.001-0.1 percent of Be, 0.01-1.0 percent of Ni, 0.05-5 percent of RE, and the balance of Al. In the invention, a high-quality melt, solid solution and a phase diagram theory are taken as guidance, a C element is taken as an efficient modifier, and a preferable formula of principal alloy elements, namely Cu, Mn and RE is adopted, so that alloy quasi-solid phase temperature range is narrowed and problems such as high heat crack tendency during casting, low strength of a product at high temperature and the like are solved; and a preferable formula of low-cost multiple microalloying elements is adopted, so that the high-strength heat-resisting aluminum alloy material is finallydeveloped.
