High-precision resistance copper alloy series
From heater wires to resistors! Copper-based resistive materials available in various forms (strips, wires, rods, etc.) to suit customer applications.
The product is various copper alloys used for resistance materials. We provide a variety of resistance materials manufactured consistently from melting and casting in various forms. We propose the optimal shape and resistance value materials tailored to your usage. CMR and HRR have low T.C.R. (Temperature Coefficient of Resistance: the rate of change of resistance with temperature) and EMF (Electromotive Force against copper thermal electromotive force), making them suitable materials for shunt resistors and chip resistors. 【Features】 - Consistent manufacturing from melting and casting - Available in various forms (bars, round wires, flat wires, rods) according to customer applications - A lineup of materials with various resistance values, including Cu-Ni series (GCN5 to GCN30) and Cu-Sn series (0.15S to 1.5S) - CMR (equivalent to Manganin) and HRR (equivalent to Zeranin 30) have small variations in resistance values, making them suitable for shunt resistors and chip resistors - EFCR-100 with a volume resistivity of 100μΩ·cm is also under development *For more details, please refer to the PDF document or feel free to contact us.
