molybdenum rod & tungsten rod

Molybdenum rods are manufactured as random length pieces or cut to customers' desired lengths.  In addition, there are three different surface processes or finishes which are provided, depending on the desired end use of the molybdenum rods.
CTOMS produces pure and lanthanated doped molybdenum rods. The lanthanated doped molybdenum rods are targeted for use in higher temperature applications where ductility is retained after recrystallization for material with smaller cross sections.

Tungsten's unique properties as a high performance material, including a melting point of 3410° C, low vapor pressure at elevated temperatures and low coefficient of thermal expansion, make tungsten rod of value in a variety of high temperature products and processes. Among them are glass-to-metal seal parts and support parts for lighting and electronics, silicon rectifier stud mounts and high temperature furnace components.

We produce pure and potassium doped (WK Type) tungsten rod. The potassium doped products are targeted for use where high temperature non-sag properties are required in smaller cross sections by the lighting and electronic industries.
