C103 (Nb-10Hf-1Ti-0.5Zr) is the most widely used alloy in the United States. The operating temperature range is between 1200 and 1400 degree Celsius. It is classified into low-strength Niobium alloys.
More than 90% of Niobium alloys used in the United States are medium-high strength Niobium alloys with Tungsten content of 10%-30%. Their high-temperature strength ranges from 77MPa at 1410℃ to 372MPa at 1315 ℃.
