Abstract：Tungsten infiltrated copper composites, W-7Cu, were prepared by infiltration. The ablation properties of tungsten infiltrated copper materials were studied by pneumatic ablation test, and the ablation mechanism of tungsten infiltrated copper materials was analyzed. The results show that W-7Cu material has good ablation resistance. Under the condition of aerodynamic ablation test, the material is basically evenly ablated, and there is oxidation phenomena and copper precipitation on the surface. The ablation mechanism is oxidative ablation of tungsten and precipitative oxidation of copper.
