Ni-Ti Alloy Materials (NiTiNOL)
Supplying perfect Ni-Ti alloy to worldwide market |
Ti-Ni shape memory alloys is a functional material．Except the high lightweight, attrition resistant, erosion resistant, good biologic compatible, and non-magnetic, it has shape-memo function and good flexibility. It is widely used in aerospace, communication, medical treatment/implantation, auto control, instrument meter, pipeline joint, glass production and other aspects in daily life. Our Ti-Ni materials have reached the international level and kept a good credit.

NiTiNOL is afamily of Ni - Ti Alloys in which transformation temperatures are changed bychanging the Ni:Ti ratio. [reference] We designate alloys by the As (austenitestart) determined by thermal analysis after a full anneal.
See ASTM Standard F2004 for a description of the thermal analysis test.
See ASTM Standard F2005 for definitions of As and other terms for shape memory alloys.
See ASTM Standard F2063 for a specification of Ni - Ti alloy mill products.
See ASTM Standard F2516 for description of tensile properties and testing.
Shape Memory Ni- Ti Alloys: Alloys having lower Ni:Ti ratio so that they are martensitic atroom temperature after cold drawing and heat treating for shape setting. Afterdeformation, will recover shape upon heating through transformationtemperature.
Body TemperatureNI - Ti Alloy: Alloys formulated to be fully transformed and superelastic at37oC.
