Material obtained by compaction and densification of metallic powder(s)

The invention relates to a compacted and densified metal material comprising one or more phases formed of an agglomerate of grains, the cohesion of the material being provided by bridges formed between grains, said material having a relative density higher than or equal to 95% and preferably higher than or equal to 98%.

A compensating balance spring for a thermally compensated sprung balance resonator including a core formed from at least one non-metallic material. The core is entirely coated with a layer which is moisture proof to render the balance spring less sensitive to climatic variations. The compensating balance spring can be applied to timepieces.
