‘Copper-base’ (Cu-base) is a term used to describe a range of alloys where Cu is the main component. To make the materials suitable for different applications (e.g. the manufacture of coinage, bells, a wide range of mechanical equipment and electrical wiring), Cu is normally alloyed with elements such as Sn, Zn, Ni, Al, and Pb. During the production process fast elemental analysis is needed to minimize errors in production and maximize production yield.
Expertise program for XRF analysis of Cu alloys
The Cu-base Expertise program delivers a complete methodology from sample preparation to quality assurance for fast elemental analysis in Cu base metals using XRF, covering the analysis of bronze, aluminum bronze, phosphor bronze, leaded bronze, brass, alloyed brass and leaded brass.
The following elements and concentration ranges are covered:
|Element||Concentration range (wt%)||Element||Concentration range (wt%)|
|Mg||< LLD – 0.3||Ni||0.007 – 33|
|Al||< LLD – 13||Cu||54.4 – 96|
|Si||< LLD – 0.6||Zn||0.013 – 43|
|P||0.001 – 1||As||< LLD – 0.3|
|S||0.0013 – 0.1||Sn||0.006 – 17|
|Cr||0.0013 – 1||Sb||0.005 – 0.5|
|Mn||< LLD – 2.3||Pb||0.005 – 21|
|Fe||0.003 – 5.6||Bi||< LLD – 2|
|Co||0.012 – 0.3|
Note: If the certified concentration is lower than the LLD value, the term < LLD has been used to indicate the lower limit of the concentration range
In addition to standards, the program includes a complete methodology, from sample preparation to quality assurance, to be used with Malvern Panalytical’s XRF systems.
