| 摘要 |
The present invention relates to a higher order beryllium-nickel alloy containing copper represented by the formula (0.4-1.50% Be)+(0<Cu</=15%)+(0<Ti</=0.6%)+(0<C</=1.0%)+(0<Mg</=0.25%), the balance Ni, and an article constructed, at least in part, of the same. Such alloys are characterized by improved machinability with optimum combination of heat treatment response, hardness, magnetic behavior, ductility, strength and cost.
