Carp 49

Carpenter 49 is a nickel-iron alloy, ideal for parts that require high magnetic permeability. It possesses maximum permeability and low core loss, as well as the highest saturation flux density of any other nickel alloy. Carp 49 has a fair resistance to weather and moisture corrosion.

Carp 49 has a machining cost factor of 6.0 when compared to steel 12L14. It can be easily welded, brazed, and soldered, as well as hot and cold worked. Carp 49 cannot be hardened by heat treatment, but can be annealed.
