The invention belongs to the field of metallic materials, and in particular relates to a barrier and explosion-proof material used as a filling material in a flammable and explosive liquid or gas storing and transporting device. The barrier and explosion-proof material is made of copper alloy and is in a cellular structure. The copper alloy comprises the following chemical components in mass percent: 25-40% of zinc, 0.8-1.2% of aluminum, 0.05-0.1% of beryllium, 0.1-0.3% of lead and balance of copper. In the invention, the copper alloy is used for replacing aluminum alloy to be a main materialof the barrier and explosion-proof material, and elements such as zinc, aluminum, beryllium, lead and the like are added to the copper alloy, thereby effectively improving corrosion resistance, yieldstrength and tensile strength of the explosion-proof material. For the barrier and explosion-proof material of the invention, the yield strength is greater than 130MPa, the tensile strength can be more than 300MPa, and simultaneously, the elongation rate can also be up to 3-12%, thus the barrier and explosion-proof material has better corrosion resistance and explosion-proof performance in the using process and can be used safely and reliably.
