This market segment includes aerospace and defense applications using Molybdenum, Tungsten, and Tantalum metal products and their alloys. The range of customers varies with each product, as does the compexity of the parts.



Isothermal Forging Dies

Molybdenum alloys TZM, MoLa, and MHC can withstand high temperatures and wear and are thus used for dies in the isothermal forging of super alloys. Aero and land based turbines can be made through the isothermal forging of super alloys into shapes. In order to improve the flow characteristics of the super alloy material, the die needs to be heated to the starting work piece temperature. This also facilitates the forging process because it eliminates cooling at the interface.
Molybdenum Isothermal forging dies are manufactured from Molybdenum alloys – Titanium Molybdenum Zirconium (TZM), Molybdenum Lanthanum (MoLa) or Molybdenum Hafnium carbide (MHC).

Missile Components

Missile rocket motor components can be made using molybdenum because it can resist high temperatures (directional vanes, and rocket nozzles). Tungsten alloy is also used in gyroscopes on missile navigation systems.


Aircraft Balance Weights

To make Tungsten heavy alloy components, WHA powder is blended, pressed, and sintered into a net shape part and then final machined to finish dimension. Near Net Shape Tungsten Heavy Alloy (WHA) provides density and strength, can balance and stabilize control surfaces of ailerons, elevators, aircraft rudders, and helicopter rotor blades and seating. In order to reduce vibration and to enhance pilot and passenger comfort, fixed and rotary wing aircrafts must have precision balancing, which can be provided by materials that are produced for the optimum weight concentration.


Due to it’s strength, wrought tungsten alloys are suitable for long rod penetrators (which are hyper-velocity, armor-penetrating rods in anti tank missiles and shells). They can also be used in fragmentation devices and certain techniques also allows the material to improve elongation or tensile strength. The long rod penetrators are also rotary forged to improve tensile properties.

Security Screening

The leading technologies for security screening at port, airport, and building sites are x-ray and backscatter, both of which can use WHA collimation and shielding systems to improve resolution and performance. These items can also be exported to the medical market but the market in security screening continues to grow.
