Zirconium alloys are solid solutions of zirconium or other metals, a common subgroup having the trade mark Zircaloy. Zirconium has very low absorption cross-section of
Zirconium is also found as an alloying element or additive in other materials. In steel, zirconium exerts a strong metallurgical effect. It has a deoxidizing and desulfurizing effect and also removes nitrogen. In free-cutting steels containing sulphur, zirconium forms sulphides (similar to manganese).
When the temperatures recah 1,500 Fahrenheit (800 Celsius), zirconium will chemically combine with oxygen and decrease the oxygen''s presence in the copper. So the copper will have less oxygen, nitrogen and hydrogen that can form putting porosity. Other properties that zirconium possesses is that it is both light in weight and very strong.
