Molybdenum (Mo) and alloys such as MoLa, TZM and MoCu are the first choice for demanding thermal applications in vacuum/inert furnaces and as base plates for power semiconductor and heatsink electronics due to its high thermal conductivity, low thermal expansion and mechanical strength at high temperatures. QSIL also offers a high precision electroplating and chemical milling capability to capture and translate the most demanding of application requirements.


Tungsten has the highest melting point of all metals and is therefore suitable for the highest application temperatures. With a density of 19.3 g/cm³, tungsten is also used as a composite material for shielding against X-rays and gamma radiation, as wear resistant coatings in multiple industries and in ultra-high temperature furnace and heat treatment applications.


Tantalum is widely used in the production of electronic components, chemical process equipment, MBE, vacuum furnace parts, nuclear and aerospace applications. QSIL has specialist production and fabrication capability to service all of these market sectors with high tolerance rolling and manufacturing technologies.


As the lightest of the refractory metals (a group of metallic elements that have an extremely high melting point and heat resistance), niobium is a highly desirable material with applications in aerospace, electronics, nuclear power and security.
