Tungsten is an extremely hard metallic element with an extremely high melting point and corrosion resistance in many harsh environments. Tungsten is resistant to oxidation attack and corrosion in acidic and alkaline media and is used in the elevated temperature filtration applications. Tungsten offers excellent high temperature mechanical characteristics and smallest coefficient of thermal expansion among all metals. The mesh itself will remain strong and stable with a high percentage of open area. Different patterns such as plain weave, twilled weave, and plain dutch weave are made on these types of weaving looms.
