The Materials You Need When You Need Them

Tungsten Alloy (aka Mallory 1000, Densalloy, Fansteel 77, Densimet)

Tungsten Alloys, which contain elements such as nickel, copper and iron, produce a host of alloys which have engineering properties similar to steel, are relatively easy to machine, and can be plated or painted to enhance their corrosion protection. These alloys are approximately 50% denser than lead resulting in a higher concentration of mass in a limited area.

 

Tungsten Alloy Products

Ed Fagan Inc. stocks Tungsten Alloys in a variety of forms and dimensions. If you do not see the size or form of Tungsten Alloys that you require, please call one of our materials experts; our sales people are very knowledgeable and can assist you. We can cut, slit, shear, or center less grind Tungsten Alloys to your exact specifications, and we also have tremendous versatility when it comes to custom sizes, packages, and unusual materials.
