Table 1: Chemical composition contrast of titanium bar for surgical implants

 

Table 1 shows: all chemical compositions meet the standard requirement GB/T 3620.1, but for Mediti No.1,2,3, US No.5 & TW No.9, the chemical composition can reach the TC4 ELl. lt shows the requirement for ELI and the control of the impurity has reach the high level.

Table 2 shows: Al mechanical properties meet and exceed the standard requirements GB/T13810, but The tensile strength of Medti is relatively concentrated and better uniformity.

Table 3 shows: the diameter deviation and external quality of the ten groups of sample rods are controlled at the same level, For high-precision medical small-mouth products, Medti's unique production process can control the shrinkage of the products within 0.03mm.

 

 

 

Remark: The above dates shows that Medti's titanium bars' quality is equalled to American, Taiwan and Russian' s but with more stable quality and more attractive price.
