What is a master alloy and how is it different from a traditional alloy? And why is the use of master alloys so important in the field of jewelry? We find out in this article.

Most of the alloys in our catalog fall under the definition of master alloy and the question of what exactly is meant by this definition may arise.

An alloy is a compound made up of two or more elements, of which at least one is a metal. The characteristics of an alloy such as hardness, strength and even color are generally different from those of the elements that constitute it, for example copper and tin, both relatively soft, form the more resistant bronze.

A master alloy is a particular type of alloy designed to be added to a pure metal, in our case gold or silver, in order to modify its characteristics. A pre-master alloy is a master alloy from which a fundamental element has been subtracted. In our field, it is generally a master alloy from which silver was stolen for logistical reasons.

FeZr Master Alloys

The ferro zirconium 80% master alloy is employed in the ferrous metal industry. Zirconium is a strong grain refiner and denitrifier, a powerful deoxidizer and also acts as an excellent sulfide shape controller. Appropriate additions of zirconium enhance impact resistance, yield strength and the hardenability of steels.

In addition, the alloy can be utilized as a zirconium additive and serves as a beneficial trace element in cobalt and nickel-based super alloys wherein iron does not have a detrimental influence.

Applications of FeZr Master AlloysFerro-Zirconium master alloy can be easily confused with ferro silicon zirconium, with dramatic effects. It is thought that a contributing factor in the Deepwater Horizon oil spill could have been the misuse of FeSiZr alloy instead of FeZr, which would have weakened components in the pipework. FeSiZr contains less than half the Zirconium content of FeZr master alloy.He is neither a climate sceptic nor a fan of inaction. But as the world moves to adopt a target of net-zero carbon emissions by 2050, Pitron worries about the costs. The figures in his book The Rare Metals War are stark. Changing the energy model means doubling the production of rare metals about every 15 years, mostly to satisfy demand for non-ferrous magnets and lithium-ion batteries. “At this rate,” writes Pitron, “over the next 30 years we… will ne

The West’s comeuppance is at hand, as its manufacturers, starved of rare metals, must take their technologies to China. It should have seen how its reliance on Chinese raw materials would quickly morph into a dependence on China for the technologies of the energy and digital transition.

By 2040, in our pursuit of ever-greater connectivity and a cleaner atmosphere, we will need to mine three times more rare earth metals, five times more tellurium, 12 times more cobalt and 16 times more lithium than we do now. China’s ecological ruination and global technological dominance advance in lockstep, unstoppably, unless the West and others start to mine for rare metals in Brazil, the US, Russia, Turkey, South Africa, Thailand and Pitron’s native France.
