Dynamet specialises in the development and application of titanium powder metal (PM Ti) technology as a substitute for conventional Ti-6Al-4V mill products or forgings for use in aerospace components. Ti-6Al-4V is the most widely used titanium alloy for both aerospace and non-aerospace applications.
Dynamet recently gained approval by Boeing Co after an evaluation of Dynamet's Ti-6Al-4V alloy product and development of a Boeing Materials Specification for powder metal titanium alloy manufactured. Dynamet is now the sole qualified supplier for Ti-6Al-4V powder metal products, meeting the requirements of the recently released Boeing Material Specification.
Dynamet also recently earned AS9100C certification, including all the requirements of ISO 9100:2008 plus further requirements relating to quality and safety. This qualification enables Dynamet Technology’s titanium powder metal products to be used as an alternative to conventionally processed titanium for manufacture of commercial aircraft components.
The Dynamet elemental blend sintering (EBS) process involves cold pressing, vacuum sintering plus an optional hot-isostatic pressing (HIP) step, all of which yields low-cost, high-density, preformed titanium alloy shapes. This process can help achieve tensile properties comparable to conventional wrought titanium products, while producing near-net shapes.
The process also supports the development of novel alloys. Since part production involves sintering rather than melting, entire new titanium alloy families incorporating the advantages of high-performance metals such as tungsten, zirconium, tantalum and niobium as alloying elements, can be created.
Dynamet Technology is working with medical device manufacturers on applications for its novel titanium alloys and metal matrix composites for advanced orthopedic components. The company is currently ramping up PM production at its Burlington facility and planning for further capacity expansions.
“As a result of more than 40 years of sustained effort, Dynamet Technology In. has achieved acceptance for use of the technology in commercial aircraft manufacturing,” said Brett Paddock, president of the ITA board.“The ITA is pleased to honour this significant achievement, which promises to promote the use of titanium in many future applications through efficient production of near-net shapes using this innovative technology.”
