鈦合金的特性與用途

鈦合金材料特性及應用功能：即在電、磁、光、熱等方面的工程材料

一、優越之物理特性：密度低、重量輕、熱膨脹係數小、不導磁、電阻係數高、低導熱率。
二、機械性能：抗高溫、金屬疲勞小、韌性佳、強度高。
三、化學性能：抗腐蝕、抗潛變性、抗氧化性、無毒性、抗菌性。

動力系統零件─鈦合金汽門彈簧（閥門彈簧Valve Spring）比一般鋼閥材質的產品設計得更輕，共振頻率比鋼簧高40％以上，以便運用在引擎凸輪軸旋轉時更輕、更快。

鈦合金汽門彈簧比一般鋼閥材質更輕巧、熱膨脹係數小、熱量傳導擴散更低、耐疲勞、彈性佳、減少油耗，以阻止在高速運轉下的不穩定以獲致最完美的性能表現。

The design of titanium alloy valve spring is lighter than ordinary steel valve. The resonant frequency is higher than steel spring by at least 40% so as to provide lighter and faster axial revolving of the engine cam.

The titanium alloy valve is more superior than ordinary steel valve in lighter, smaller thermal expansion coefficient, lower in thermal expansion, fatigue durable, good elasticity, and reduces oil consumption so as to prevent instability while revolving at high speed and obtain perfect performance.

動力系統零件─鈦合金汽門（進氣閥、排氣閥）比一般鋼閥材質的產品設計得更輕量化，可幫助進、排氣動作的速度，提升性能， 進一步能幫助加速。

鈦合金汽門比一般鋼閥材質的產品更輕化、膨脹係數小，於進、排氣時可提升它的氣密動作，幫助完全燃燒，同時減少噪音、摩擦、油耗、震動及廢氣。


Power system part – the design of titanium alloy valve (inlet valve, exhaust valve) is lighter than ordinary steel valve.  The part can help in the inlet and exhaust speeds, improves the performance and further help in the acceleration.

The titanium alloy valve is more superior than ordinary steel valve in lighter, smaller expansion coefficient, improves the tightness in inletting and exhausting, helps in complete combustion, and at the same time reduces noise, friction, oil consumption, vibration, and gas waste.
