GB 24627 -2009 standard and the adjustment range of Af temperature which can be realized by the NiTi titanium tubing price material is -40C-85C nickel-titanium wire Specification of NiTi alloy wire Ф010 mm ~ Ф700 mm-Surface state of wire oxidation state (including black surface oxidation state blue oxidation state amber oxidation state etc) Pickling state As its name suggest nitinol is a binary alloy of nickel and titanium that is subject to changes in temperature and mechanical stress that result in that existence of two different The same crystal structure phases ie austenite phase and martensite phase The phase transformation sequence of NiTi alloy during cooling is parent phase (austenite phase) -
R phase-Martensitic phase The R phase is rhombohedral and the austenite is at a higher temperature (greater than the temperature at which the austenite starts) When or when the load is removed (the external force is removed from Deactivation) the Titanium welding pipe cube is hard The shape is relatively stable And horses The martensite phase is the state at a relatively low temperature (less than Mf the temperature at which martensite ends) or when loaded (activated by an external force) Hexagonal malleable repetitive less stable more deformable (II) Martensitic transformation occurs so the alloy shows different ti6al4v eli mechanical behavior from ordinary materials and its elastic limit is much larger than that of ordinary materials And it no longer obeys Hooke's law In contrast to shape memory properties superelasticity is not thermally involved All in all 3d titanium wire hyperelasticity refers to a When the archwire is heated above 400oC the superelasticity begins to decrease 3 Sensitivity of temperature change in oral cavity The orthodontic force of stainless steel wire and CoCr alloy orthodontic titanium round bar wire is basically not affected by the temperature in oral cavity Ring
Corrosion resistance Studies have shown that the corrosion resistance of nickel-titanium wire is similar to that of stainless steel wire 5 Toxicity resistance The nickel-titanium shape memory alloy has a special chemical composition that is it is a nickel-titanium alloy containing about 50% nickel Nickel is known to have carcinogenic and cancer-promoting effects In general the surface layer of titanium oxide acts as a barrier making the Ni-Ti alloy have a good Biocompatibility TixOy and TixNiOy in the surface layer can inhibit the release of Ni 6 Gentle ti6al4v orthodontic force Currently commercially available orthodontic wires include austenitic stainless steel wires cobalt-chromium-nickel alloy wires Nickel-chromium alloy wire Products include pipes bars plates wires strips flanges forgings and pipe fittings Products are used in petrochemical aerospace shipbuilding energy chemical industry electronics environmental protection machinery and instrumentation and other fields (13-6-81-71-31-45zx) Return to Sohu to see more Responsible Editor yunchtitanium.com
