Dura-Bar Right for Defense Industry Applications

 

rocketIn military equipment, Dura-Bar ductile iron is appropriate for many of the components typically found in other industries -- manifolds and other hydraulic components, gears and pulleys, etc.  However, Dura-Bar's material consistency and quality also make it a better choice than iron castings for a number of applications unique to modern weapon systems.

For example, Dura-Bar has been used by defense industry manufacturers for shell casings and machine gun parts.  Shell casings for bombs and rockets designed to be dropped from helicopters or shot from platforms are prime candidates for conversions to castings.

Because a material flaw can have severe consequences for military personnel handling ordinance and employing weapons systems, using Dura-Bar is often preferable to traditional iron castings.  As evidenced by Dura-Bar's Zero Defect Guarantee, Dura-Bar is free of the porosity, slag, hard spots, shrinkage, and other defects that are associated with traditional static cast methods.  Also, Dura-Bar is more machinable with better chip control and longer insert life, which means that parts can be produced faster and at a lower total per-part cost.

It's important to note that military contractors must adhere to tight specifications and usually have little flexibility in substituting materials.  A change in the weight, for example Dura-Bar being lighter than steel, would affect the trajectory of the shell as well as the blast pattern of its explosive, therefore the best opportunities are those applications already specified as cast iron.
