Book Description
Copper-base alloys are so numerous and varied in composition that there are few simple tests which can give reliable indications of all the alloying elements. There are tests to show the presence of the elements tin, lead, silicon, etc. which, taken together with such other factors as color and a knowledge of the origin or application of the alloy, will serve to classify the material within certain limits. These tests generally involve dissolvinga small portion in a beaker or test tube and observing the effects of added reagents. Spot tests are not always reliable, due to the intense blue color of the copper masking the effects of subsequent reactions. There is no reliable substitute for the spectrograph except a complete qualitative chemical analysis with all its time-consuming operations.

Book Description
The analyst should familiarize himself with the metals and alloys he expects to encounter including normal processing methods involved in fabricating the finished products. He should become familiar with the flow diagrams and procedures for determining constituent alloys in the various metal families listed in this publication. Normal cleaning processes must be observed on metals at test areas to remove dirt, grease, oxides, or metallic coatings such as nickel, zinc, tin, aluminum, etc., prior to performing a test. Cleaning solvents, files, or abrasives can be used as applicable. After properly cleaning the test area, the analyst should follow detailed instructions for each test relative to chemicals used, number of drops, and time allowed for each reaction. Procedures for determining constituent alloys in various metal families can be used independently of the flow diagrams; however, some tests on the flow diagrams refer the analyst to tests listed in the metal family procedures. Qualitative analysis can be performed on unknown metals and alloys by following the procedures for determining alloys in a given alloy family.
