Each form is composed of the same elements, but the percentages (%) of constituent elements differ. One is matched to Iron. The other can be matched to Copper or CHROMEGA ® . When ordering "matched pairs," be sure to specify SPCI with SPIR and SPCC with SPCP or SPCH Ordering Example: (1) SPCI-001-50 0.001 Inch, Constantan, 50 ft Spool, CAD30.50 plus (1) SPIR-001-50 0.001 Inch, Iron, 50 ft Spool, CAD30.50, CAD30.50 + 30.50 = CAD61.00
