For the material choice of the LO2-kerosene rocket manufacture, the compatibility experiment of material with kerosene was carryied out. In the experiment, some capabilities were measured on mass, tensile strength, corrosion rate, metallographic structure of metal, volume, mass, rigidity of nonmetal and aspect, component, acid volume, colloid, conductance, mechanical impurity of kerosene. From the integrated analysis of those capabilities, a conclusion was obtained that the compatibility is acceptable of kerosene with steel F151, steel wire 1Cr18Ni9Ti, alloy QAL-4, alloy 3J1, Fs-46, Fs-3.
