promotion tension spring
.Diameter : 0.1mm-8mm
.Material : Nickel titanium alloy

                          promotion tension spring
                               1. Memory alloy except having unique shape memory function , still have wear resistance, corrosion resistance, high damping and hyperelastic superior.

                               2. Expansion contraction rate in above 20%. Fatigue life achievable 107 times, damping characteristics than normal spring high 10 times, the corrosion resistance of the optimal

At present the best medical stainless steel, so can satisfy all kinds of engineering and medical application requirements, it is a kind of very good Functional materials.

                               3. Production can be applied in glasses frame, women's bra, mobile phone antenna, dental arch wire, instruments and other areas of high quality memory Alloy wire.

                               4.   Memory alloy has used in the connection pipeline union and the automated control aspect, makes the drive pipe with the memory alloy to be possible to replace the welding, the method is in the low temperature time the jet in all expands approximately 4%, when the assembly the sleeve joint same place, as soon as passes through the heating, the drive pipe contraction restores form, and forms closing joint parts.

                               5. Because the memory alloy is a "alived alloy", using it in certain temperatures shape variation, can design a variety of control devices
