WitrynaThe maximum conductivity of ETP copper occurs at approximately 200 ppm of oxygen as shown in Figure 3. Consequently, oxygen content for ETP copper is generally in the range of 175 to 450 ppm. Lower oxygen values are usually avoided because of a propensity to hot cracking resulting from uncombined impurities. WitrynaHowever, in low cost commercial brasses its content is often greater than this value, due to the lack of strict control on alloying and impurity contents. Lead is insoluble in copper-zinc alloys and during solidification it precipitates forming globules both at grain boundaries and within the matrix. phone number for talbots in winston salem ncWitrynaThis study discusses the influence of matrix effects on relative sensitivity factors in secondary ion mass spectrometry for a quantification study of major and impurity elements in standard brass reference materials.
