Measuring percentages is：Nb：16 ~ 22%, Zr：3.0 ~ 5.5%, Ta：8 ~ 12%, Fe：0.1 ~ 0.6%, Ca：0.2 ~ 0.6%, surplus is Ti
With inevitable impurity.
Preferably, the titanium alloy carries out following heat treatment step after boss semi-finished product are cast as：
（1）Quenching：Boss semi-finished product after casting are inserted in resistance furnace, 300 ~ 320 DEG C, insulation are heated to
10 ~ 12min, then proceedes to be heated to 620 ~ 650 DEG C, is incubated 10 ~ 12min, then proceedes to be heated to 780 ~ 820 DEG C, insulation 1 ~ 2
Hour, carry out strong water spray quenching, quenching to room temperature.
（2）Timeliness：Boss semi-finished product after quenching are inserted in aging furnace, 320 ~ 360 DEG C, Ageing Treatment are heated to
After 5 ~ 6 hours, slow cooling to room temperature.
（3）Deep cooling：Boss semi-finished product after Ageing Treatment are inserted into deep cooling box and carry out subzero treatment, cryogenic temperature
For -120 ~ -150 DEG C, subzero treatment soaking time is 25 ~ 35min, and insulation recovers to room temperature after terminating.
（4）Tempering：Boss semi-finished product after subzero treatment are inserted in tempering furnace, 120 ~ 180 DEG C, insulation are heated to
25 ~ 35min, comes out of the stove and is air-cooled to room temperature.
（5）Process of refinement：Boss semi-finished product after tempering are subjected to fine design by milling angle operation, obtained
Boss finished product.
Preferably, the outer cover body of the mobile communication equipment is rigid plastics, aluminium alloy or magnesium alloy, by shell sheet
Body is affixed with boss, forms the mobile communication equipment shell of high intensity.
Preferably, the mobile communication equipment is mobile phone..
Effect of the invention is that：
1, it is improved by the component content to titanium alloy so that its intensity and modulus of elasticity have obtained significantly changing
It is kind.
2, pass through the improvement to titanium alloy heat treatment mode so that the microstructure of titanium alloy generates change（That is the heat
Processing method implies specific structure）, so as to its fracture strength, yield strength is obtained for significantly improves.
3, by adding subzero treatment in heat treatment process, and by subzero treatment and timeliness, temper it is suitable
Sequence cooperate, and Deep Cryogenic Treatment improvement so that modulus of elasticity, yield strength of boss etc. have been obtained significantly
The improvement of degree.
4, by the way that the heating process of quenching is divided into triphasic heating so that the microstructure of titanium alloy is more uniform steady
It is fixed so that its modulus of elasticity is improved.
