Copper and copper alloy reference materials

(Received 5 November 1991)

Abstract--The present column lists currently available copper and copper alloy reference materials. Pure copper, brasses, bronzes, various copper base alloys, copper binaries and setting up samples have been considered. Included are three tables that provide an easy-to-use survey. The following information is covered: the name of the material, the sample code, the producer, the reference to recent certification, the names and addresses of the suppliers frdm whom the reference material may be obtained, and specific remarks.

EMISSION and X-ray spectrometric and other modern instrumental methods have found their way into industrial laboratories with various degrees of automation and computerization. Most of these high-speed techniques are dependent upon comparative methodology that requires calibration and validation with so-called “reference materials”.

Major roles of the reference materials are attention to Quality Control (QC) and Quality Assurance (QA). QA means that a laboratory must take measures to assure that an analytical result is a good representation of the “true value” of a constituent. QC means that special precautions must be taken to ensure that the entire analytical process will be under control during the analysis of all similar samples.

Incorrect values can be very costly for both producers and customers, resulting in lost time, rejected products, etc. To remove any doubt and provide confidence in each analytical result, good practice should always include the analysis of a series of well characterized reference samples of varied composition (if possible, from different sources) along with each batch of samples under the same analytical conditions. They will help to critically evaluate the analytical system for accuracy, to assure reliability, to monitor the day-to-day operational performance of the laboratory, to maintain consistent and uniform levels of quality, and to perform corrective actions as necessary. Reference materials are also appropriate systems for validating new procedures and comparing data from different laboratories.

Certain properties of metals and alloys may be critically dependent on the presence of trace amounts of minor constituents. The determination of trace and ultra-trace levels is a critical concern in many sectors. The determination of gaseous impurities is also often important.

Ideally, in order to obtain the most accurate analytical results, the reference material should have the same or nearly the same composition of the unknown samples being run to the extent that it should also match with respect to the levels of trace elements present. Therefore, the matrix effects are minimised and only small interelement corrections are needed. A large set of appropriate standards is thus required.

Reference materials for ferrous metallurgy have been listed previously [1,2]; our latest column, on non-ferrous metallurgical materials, was dedicated to aluminium and aluminium alloys [3]. The intention of the present instalment is to gather commercially available copper and copper alloys.

For the preparation of this issue, inquiries were addressed to various certifying

749

institutions, producers, commercial firms and official distributors. Only agencies who replied to our request for information at the time of writing are mentioned here.

The majority of the copper reference samples have been prepared as chips or disks. In some cases, the material is in the form of mushrooms, pins or wires.

The presentation of the present survey follows the general style we have adopted in our previous instalments of the column.

Three tables have been prepared to provide, in a convenient way, a maximum of necessary information to the user of reference samples, and to make it easier for him to find what he is looking for.

In Table 1, copper materials have been grouped into seven principal classifications

1. Pure copper 2. Brasses 3. Bronzes 4. Various copper base alloys 5. Copper ores and concentrates 6. Copper binaries 7. Setting up samples.

The table is organised as follows.

(1) The name of the material is given in the first column.

(2) The sample code, i.e. the usual abbreviations given by the originator, is shown in column two.

(3) The acronym of the producer is stated in the third column.

(4) Recent references of certification, reports, catalogues or preliminary information are identified by a number preceded by the letter R. The number in the relevant column refers to the list presented in Table 2.

(5) The supplier from whom the sample may be obtained is identified in a similar manner (using S as the first letter). The name and addresses of the suppliers of the reference materials mentioned in Table 1 are given in Table 3. In this manner, readers are able to obtain further information directly from such sources (catalogue, price list, quantity of the supply, details of the purchase procedure, etc.).

(6) Specific remarks that may assist the reader in his choice of samples are indicated in the last column.

In preparing the paper, unfortunate oversights might have occurred and many materials possibly used as standards may have been omitted for whatever reasons. In such cases we apologise to the readers. We will ask them insistently to inform us of their remarks and suggestions so that we can take these into account in the future, and improve the usefulness of this column. Producers and suppliers of reference materials are invited to send pertinent information about their products and services at the address given above.

Acknowledgements-I am grateful to Professor P. W. J. M. BOUMANS for the enthusiasm he has invested in the present reference material column and to V. MIOCQUE for her kind assistance. I also wish to express my sincere thanks to various agencies for their co-operation in providing ample information and numerous documents for this column.
