Alloys based on zirconium having proportional amount of tin, iron, chromium and oxygen

摘要

A zirconium alloy containing on weight basis, 0.4-1.2% tin, 0.2-0.4% iron, 0.1-0.6% chromium, not higher than 0.5% of niobium and balance oxygen and zirconium, wherein the sum of weight proportions of tin, iron and chromium is in the range from 0.9 to 1.5%; and a zirconium alloy as above wherein the proportions, expressed by weight %, of tin XSn, iron XFe, chromium XCr, niobium XNb and oxygen Xo satisfy the equation 0.18 XSn+0.15(XFe+XCr)+0.13XNb+4.72Xo>/=0.95.
