XRF(X-Ray Fluorescence) spectra of Cu alloys such as CopperBeryllium(CuBe), CuproNickel(CuNi), Brass, PhospherBronze(PBronze) were analyzed using Hand Held XRF device. We confirmed that the energy of x-ray emission line measured in each sample is a very good agreement with the emission energy of each element, also that the intensity of spectrum is consistent with the expected one. In case of Brass, the Cu:Zn ratio obtained from the spectral analysis was 61:39, and there was an error of about 6.5% in comparing to the actual ratio 65:35 of alloy. In case of CuNi, the Cu:Ni ratio was 70.4:29.6, and also there was an error of about 6.5% in comparing to the actual ratio 75:25 of alloy. This error tended to be similar to that of Brass. We thought that the error was somewhat larger because it was analyzed only with XRF spectrum, but it will significantly be reduced if the characteristics of x-ray source and the matrix effects in a sample are considered.
