C107 is a copper alloy with a small addition of arsenic which provides the alloy with enhanced tensile strength properties at elevated operating temperatures up to 300°C. As well as increasing the softening resistance, the arsenic addition also enhances corrosion resistance in specific environments.
Arsenical copper is de-oxidised, which gives it freedom from hydrogen embrittlement, making it ideal for applications requiring welding and brazing. C107 has excellent fabrication characteristics and is typically specified in boiler work, especially locomotive fireboxes.
