Recent developments in titanium (Ti) powder for Metal Injection Molding (MIM) highlight several key trends

1. Technological Advancements in MIM Processes

The MIM process, recognized as a fifth-generation metal forming technique, has been effectively applied to titanium and its alloys. This method enables the cost-efficient production of complex, high-precision components, as demonstrated by Xiaomi's use of MIM for titanium frames in their smartphones

2. Development of Specialized Titanium Powders

Companies like Velta have successfully tested their proprietary titanium powders for MIM applications. These advancements suggest a move towards more sustainable and efficient titanium powder production methods, such as the Velta Ti Process, which aims to reduce waste and carbon emissions. 

3. Increasing Demand for Titanium in MIM

The global MIM market has been experiencing significant growth, with an annual increase of approximately 14% as of 2011, and the market valued at around $1 billion USD. While stainless and low-alloy steels have traditionally dominated, there's a notable rise in the use of titanium powders, driven by their superior properties and expanding application areas.

4. Importance of Oxygen Control in Titanium Powders

Controlling oxygen levels in titanium powders is crucial for achieving high-performance MIM parts. Recent studies emphasize the need for precise oxygen management to enhance the mechanical properties and reliability of titanium components produced via MIM.

These trends indicate a dynamic evolution in the use of titanium powders for MIM, with ongoing innovations aimed at improving material properties, process efficiency, and expanding application scopes
