Quality Construction

Tungsten

Doped Tungsten	W31: Standard doped tungsten with undeformable property W41: Doped tungsten with low recrystallization temperature than W31 and secondary workability W71: Co addition doped tungsten with undeformable and vibration resistance property W91: The best to use at ultrahigh-temperature with undeformable property
Thoriated Tungsten (Thori-Tun®)	W51: Tungsten for lamp filament combining high temperature strength with 0.7%ThO2-W and ThO2 and vibration resistance property enhanced by addition of Co. W53: 1.0%ThO Tungsten 2-W standard Thori-Tun for electron tube W54: 1.7%ThO2-W standard Thori-Tun for electron tube W56: 2.0%ThO2-W Thori-Tun for discharge electrode
Rrhenium Tungsten	H30: 3%Re-W Tungsten with intensity at room air to high temperature and ductibility after recrystallization. H35: 15%Re-W Alloy wire with high electric resistance and mechanical strength H36: 26%Re-W Alloy wire with higher electric resistance and mechanical strength H37: 3%Re-W Rrhenium Tungsten for probe pin H38: 5%Re-W with larger thermo electromotive force than that of platinum thermocouple, good linearity and ability to measure up to 2300 degrees Celsius (+) H39: 26%Re-W same as H38(-)

Molybdenum

M10: Pure Molybdenum
M20: Co/Sn added Molybdenum with stable mechanical property after thermal process and work and range characteristics
M40: Doped Molybdenum with high recrystallization temperature, high temperature strength and ductibility after thermal process
