Tungsten, Tantalum & Titanium: High Temp and Corrosion Resistant Alloys
Tungsten, Tantalum & Titanium
High Temperature and Corrosion Resistant Alloys
Tungsten, Tantalum, and Titanium are part of a group of metals known as the refractory metals group. These types of metals are used for their chemical and electrical properties.
TUNGSTEN
Organizations depend on Tungsten and its alloys for their high strength, melting point, and high-density properties, and high temperatures. Tungsten can be used as an additive to enhance physical properties in steel. When used in the aerospace industry, Tungsten and its alloys are applied to blades used on jet engines. In the automotive industry, they are applied to electronics. And, in the military industry, Tungsten is applied to wear-resistant parts. Additional applications extend much farther than these few. In fact, Tungsten weights were used in Mars on a Mars Exploration Rover and Pathfinder.

TITANIUM
Titanium is extremely durable, corrosion/erosion resistant, and has high intrinsic shock resistance. In addition, it has high fatigue strength when used in the air, is a low-density alloy, and has good thermal conductivity. A variety of industries depend on it including but not limited to: military and defense, aircraft and aerospace, and healthcare. It has been applied to everything from dental implants to consumer electronics.
