Titanium FAQs

  • What are the main material properties of Titanium alloys?
    Titanium alloys boast excellent strength-to-weight ratio, corrosion resistance, and high temperature resistance. They also exhibit good biocompatibility, making them widely used in aerospace, medical devices, and chemical industries.
  • Which titanium grade is most suitable for machining?
    The best grade of titanium depends on specific requirements, but Grade 4 titanium is widely acknowledged as the strongest form of pure titanium, despite being less malleable than other grades. It offers exceptional corrosion resistance and impressive ductility, making it favored for demanding applications. Additionally, titanium's lower density makes it lighter than certain steels like stainless steel, enhancing its attractiveness in weight-sensitive industries.
  • What makes CNC machining titanium challenging?
    The CNC machining of titanium presents a myriad of challenges stemming from its unique properties. Firstly, its low thermal conductivity leads to cutting tools absorbing a significant portion of the generated heat during machining, posing thermal management issues. Secondly, titanium's propensity to demonstrate adhesive behavior can lead to the formation of long, stringy chips and the accumulation of an edge during machining, requiring meticulous chip control strategies. Furthermore, its low modulus of elasticity contributes to springback and chatter, impacting precision and surface finish quality. Lastly, titanium's high work hardening tendency renders it more resistant to deformation, complicating the attainment of desired shapes and dimensions and requiring meticulous machining techniques.
