Overview of Titanium Iron Powder

Titanium iron powder, sometimes referred to as ferrotitanium powder, is a metal powder composed of titanium and iron. It is manufactured by alloying titanium and iron through melted processing and powder metallurgy methods.

Some key features of titanium iron powder include:

  • Composite of titanium and iron alloy
  • Available in various compositions and ratios of Ti and Fe
  • Exhibits combined properties of titanium and iron
  • Powder form allows processing into other shapes
  • Used for metallurgical, chemical, and nuclear applications
  • Cost advantage over pure titanium powder

Titanium iron powder offers benefits like high strength, heat resistance, low density, and more depending on the composition. It is widely used as an additive for steelmaking, in chemical processes, as a neutron absorber, and in other applications requiring titanium’s properties.

This guide provides a detailed overview of different types, compositions, properties, applications, suppliers, costs, and other key information on titanium iron powder.

Types and Composition of Titanium Iron Powder

Titanium iron powder is available in different compositions categorized by the ratio of titanium to iron. Common types and composition ranges include:
