Liquidmetal® alloys are a unique class of highly engineered metals that are extremely strong due to their glass-like crystalline structure.
Primarily composed of zirconium, titanium, copper, nickel and beryllium, liquidmetal is created by breaking down constituent metals to their molecular level, mixing them together, and then rapidly cooling the amalgam in order to create an amorphous crystalline structure that, atomically, is more similar to liquid than metal.
This crystalline structure eliminates weaknesses that cause structural defects in pure metals and traditional metal alloys. As a result, liquidmetal is stronger than titanium, lightweight, as well as corrosion and wear resistant. Read More...

The world's 10 biggest palladium producers accounted for 6.5 million ounces of refined palladium in 2012, over 95 percent of primary production.
Russia'sNorilsk Nickel remains the world's largest producer by a significant margin, accounting for over 40 percent of total palladium production. Anglo Platinum (Amplats) and Impala Platinum (Implats) round out the top three and are the only other producers that refined over 1 million ounces last year.
Palladium is a soft, silvery platinum group metal that is used in the production of autocatalysts, multi-layer cell capacitors and jewellery. The metal's ability to absorb carbon monoxide and purify hydrogen makes it integral to the manufacture of automobile catalytic converters, which account for over half of all demand. Read More...

According to the Financial Times, banks and traders that form the core of London's gold market are collaborating in order to protect prices for the precious metal against manipulation.
In particular, the London Bullion Market Association (LBMA), which includes the likes of Barclays, Goldman Sachs and JP Morgan Chase, is looking at whether benchmark gold prices that it publishes meet principles set out by international securities regulators.
The move comes in the wake of the Libor scandal, whereby the benchmark rate for interbank lending was manipulated by banks and brokers, resulting in fines of USD 3.5 billion.
The LBMA is an international association centred in London that represents the wholesale market for gold and silver, not only by setting prices twice daily, but also by working on refining and documentation standards. Read More...

As any whisky connoisseur knows, the metal in which a spirit is distilled can have a strong impact on the flavour profile of the product.
Copper is the metal of choice for whisky-makers because of its malleability, heat conduction and, most importantly, it ability to neutralize sulphur compounds.
Sulphurous compounds, such as di-methyl trisulphide (DMTS), naturally form during the whisky distillation process. DMTS is an unwanted chemical that is associated with a rotten vegetable or rubbery smell.
By distilling in copper pots, or using copper column stills, these sulphery notes can be removed, leaving a whisky that has more fruity and floral aromas. Distillation in stainless steel, or less contact with copper during the disillation process, will result in spirit with 'off-notes' that smell sulphery or yeasty. Read More...
