Molybdenum

Molybdenum (also known as "Moly") has an extremely high melting temperature of 2620°C. It retains tensile strength at temperatures above 1000°C, exhibits a low coefficient of thermal expansion and good electrical conductivity properties which are favorable for creating molybdenum components and assemblies for the electronic, semiconductor and lighting industries. Sylhan can provide molybdenum parts, machined and lanthanated, based on your specifications.

TZM

TZM is an alloy of molybdenum containing titanium and zirconium developed to exhibit greater tensile strength than pure moly. TZM also has a higher recrystallization temperature of 1425°C. Applications for TZM moly alloys resemble molybdenum but result in products that may exhibit greater service time. Industrial applications for TZM machined arc chambers include ion implantation and other semiconductor products, while medical applications for TZM include rotor shafts and cathode assemblies for X-ray targets.

Inconel

Inconel alloys are typically used in extreme environments due to its high corrosion resistance and yield strength over a wide range of temperatures. When faced with intense heat, an oxidized layer forms to prevent further damage. There are a variety of inconel alloys for an even wider variety of uses, such as Inconel 625, which is very weldable and commonly used in aerospace components.

Inconel

Niobium

Niobium has a melting temperature of 2470°C, exhibits good thermal conductivity, and its high corrosive resistance makes it the material of choice for heat exchanger applications in industries such as pharmaceuticals. Niobium components may also be used in applications that exhibit high temperatures.
