钛合金标准件就是普通的标准件,只不过他所用的材料是钛合金,机械性能,化学元素要合乎钛合金标准件相关标准而已.
加工,做,使用,经销美国螺栓螺母,美制螺栓螺母,美标螺栓螺母,一定要拥有美国螺丝标准.你应该买一套美国最新紧固件标准大全《IFI英制紧固件标准手册》第八版)(英文版)(2011年出版),专家才是赢家,拥有标准才会拥有相关业务.

钛合金标准件是以钛为基加入其他元素组成的合金。钛有两种同质异晶体：882℃以下为密排六方结构α钛，882℃以上为体心立方的β钛。
　　钛合金板　　硬质表层;在600℃以上时，钛吸收氧形成硬度很高的硬化层;氢含量上升，也会形成脆化层。吸收气体而产生的硬脆表层深度可达0.1～0.15 mm，硬化程度为20%～30%。钛的化学亲和性也大，易与摩擦表面产生粘附现象。
　　导热系数小、弹性模量小
　　钛的导热系数λ

15.24W/(m.K)约为镍的1/4，铁的1/5，铝的1/14，而各种钛合金的导热系数比钛的导热系数约下降50%。钛合金的弹性模量约为钢的1/2，故其刚性差、易变形，不宜制作细长杆和薄壁件，切削时加工表面的回弹量很大，约为不锈钢的2～3倍，造成刀具后刀面的剧烈摩擦、粘附、粘结磨损。
