Types of Bullion and their Uses

May 22, 2019 07:00

A great way to diversify an asset portfolio is purchase to bullion. Of course, the types of precious metals and quantities you buy them are an important part of diversification strategies – but what about the types (i.e. form factors) of bullion?

One of the common questions first-time investors ask once they see all of the ingots, bars, coins, and other types of bullion available is “what’s the difference?” Since the inherent value is the same, there is no strategic advantage to owning, say, coins instead of bars. But, there are some reasons why investors may prefer one form factor over others.

For example, bullion coins’ smaller sizes and difficult to counterfeit designs give them better liquidity compared to ingots, bars, or rounds. However, seigniorage fees typically push the cost of bullion coins over the spot price for their metal content. So if you can afford to purchase more metal at once, and you have a secure space to store that amount, you’d save some money upfront by purchasing bars instead of coins.

In the infographic below, we’ve outlined the key differentiators for the most popular bullion products: bars, coins, and fractional.

Humanium - A New Alloy for a Good Cause

Humanium - A New Alloy for a Good Cause

Peace does not come through prayer, we human beings must create peace. Also, power of truth is more powerful and enduring than the power of gun. Therefore, the Humanium Metal by IM Initiative is a laudable effort at making this world more peaceful through concrete human action.” -Dalai Lama

Does that make Humanium the antithesis of prayer? Not exactly, but it does make it a commendable follow-up. So what exactly is Humanium metal?

Humanium is a metal that's made from melted-down guns. More specifically, it is recycled metal from illegal firearms obtained from gun destruction programs.

The Story behind Humanium

The brainchildren behind Humanium are two Swedish creative agencies, Great Works and Akestam Holst. Their pro bono campaign, Humanium Metal by IM, garnered attention when it won the Grand Prix for innovation at the 2017 Cannes Lions International Festival of Creativity.

The campaign also drew the interest of IM Swedish Development Partner, which has a long history of working in countries where gun violence is hindering development.

They coordinated their efforts and in 2016, launched the first weapons destruction program dedicated to Humanium Metal by IM in El Salvador. The program generated three tons of Humanium from nearly 5,000 weapons. The initiative has since expanded to Guatemala, with Honduras and Columbia expected to follow.

How Humanium Is Used

Humanium can be recycled into all sorts of things, including buildings components, machinery, utensils, tools, bicycles and jewelry. In fact, Sweden’s Arild Links currently sells a charm bracelet made from Humanium. And last year, watchmaker TRIWA began using Humanium to create custom watches.

And there’s more to come. Through future brand collaborations, Humanium Metal by IM hopes to explore the production of even more Humanium-based products.

Is Humanium Certified?

Since Humanium is made from seized firearms in full cooperation with local governments, each batch comes with documentation provided by their respective melting plants, along with technical specifications. The process is also monitored by the non-profit association, Swedish Fundraising Control.

Consumerism with a Cause

Humanium might be the perfect metal for socially conscious consumers who prefer to buy from brands with pro-social messages and ethical business standards. Humanium Metal by IM uses proceeds from its sales to fund nonviolence initiatives in the areas it sources from. By purchasing Humanium products, consumers can, in turn, help the world become a better, more peaceful place.

Scientists Create New 'Gold-Like’ Catalyst from Copper

Scientists Create New 'Gold-Like’ Catalyst from Copper

According to a study published in Science Advances, a team of researchers with the Dalian Institute of Chemical Physics at the Chinese Academy of Sciences in Liaoning have discovered a way to transform copper into a new material with catalytic properties similar to gold.

To create the new material, the researchers shot a copper target with a jet of high temperature, electrically charged argon gas. The fast-moving ionized gas particles blasted copper atoms off the target. The atoms then coalesced onto the surface of a specialized collecting device to form a layer of sand-like matter with individual grains measuring only a few nanometers in diameter.

Using this material as a catalyst, the scientists were able convert carbon (as coal) into an alcohol at a level of efficiency similar to what could be achieved with a gold catalyst.

Compared to gold (or other precious metals), normal copper catalysts are inefficient to work with because they corrode too quickly. This is because copper atoms have fewer electrons in less stable arrangements compared to gold atoms. According to the study's lead researcher, Professor Sun Jian, the electrified argon gas "inject[s] a large amount of energy into copper atoms [to make] the electrons more dense and stable." This is what enables the resulting material to resist high temperatures, oxidization, and erosion at levels comparable to gold.

Although this form of modified copper may not totally replace gold, the researchers are hopeful that their discovery will significantly reduce the use of precious metals in industrial applications.
