Nickel Platinum Alloy (NiPt(99.95 %))-Sputtering Target

Nickel Platinum Alloy (NiPt(99.95 %))-Sputtering Target introduce:

Characteristic




Platinum-nickel alloy, a platinum alloy with platinum-based nickel added.It is a continuous solid solution at high temperature and forms two superstructure ordered phases NiPt and Ni3Pt at low temperature.It has AuCu and Cu3Au structure respectively.In platinum-rich alloys, with the increase of nickel content, the density of the alloys decreases, the mechanical properties and resistivity at room temperature increase, and the elongation and resistance temperature coefficient decrease.When heated under oxidation conditions, selective preferential oxidation of nickel occurs in platinum nickel alloy, resulting in Nil).Therefore, with the increase of nickel content, the anti-oxidation and anti-corrosion ability of platinum-nickel alloy decreases, which leads to the decrease of the high-temperature durable strength and creep life of the alloy.Nickel-rich alloys are ferromagnetic and Curie temperature decreases with the increase of platinum content.Platinum-rich alloys are paramagnetic.




Application




Platinum-nickel alloy is an important elastic alloy, which is used to make elastic elements such as tensions, springs, reeds and brushes in precision instruments.
