Metal Profile: Magnesium

What is magnesium? Magnesium is the lightest of all the metal elements and is primarily used in structural alloys due to its light weight, strength and corrosion resistance.

Metal Profile: Molybdenum

What is molybdenum? Molybdenum (often referred to as 'Moly') metal is valued as an alloying agent in structural and stainless steels because of its strength, corrosion resistance and ability to hold shape and operate at high temperatures.

Platinum Group Metals (PGMs)

The PGMs are the densest known metal elements. Exceptionally rare, the six metals naturally occur in the same ore bodies. They are highly durable and, due to their high value, often recycled, giving them long life cycles.

Metal Profile: Platinum

Platinum is a dense, stable and rare metal that is often used in jewelry for its attractive, silver-like appearance, as well as in medical, electronic and chemical applications due to its various and unique chemical and physical properties.

Metal Profile: Silver

What is silver? Silver is a soft, lustrous metal that has a long history as a medium of exchange in coins and currency, and as a store of wealth (silver bullion). A precious metal, silver has been used in jewellery and as a decorative metal for millennia, while, more recently, it has become an important metal for electronic, industrial and...

Metal Profile: Cobalt

What is cobalt? Cobalt is a shiny, brittle metal that is used to produce strong, corrosion and heat resistant alloys, permanent magnets and hard metals.

Minor Metals

What are minor metals? The term 'minor metals' is used to describe about 40 elemental metals that are normally produced as by-products and not traded on any major exchanges.

Metal Profile: Uranium

What is uranium? Uranium is a dense, radioactive element that is primarily extracted and refined as a fuel source for nuclear energy. In its metal form, uranium is used as a radioactive shield as well as in military armor and ammunition.

Metal Profile: Mercury

What is mercury? Mercury, or 'quicksilver' as it is otherwise known, is a dense, toxic metal element that exists in liquid form at room temperature. Produced and studied for millennia, mercury's use has steadily declined since the 1980s as a result of greater attention to the negative health impacts that it has on humans and the environment.

Metal Profile: Titanium

What is titanium? Titanium is a strong and lightweight refractory metal. Alloys of titanium are critical to the aerospace industry but, due to their numerous unique properties, are also used in medical, chemical and military applications, as well as in sporting goods.

Metal Profile: Chromium

What is chromium? Chromium metal is most widely recognized for its use in chromium plating (which is often referred to simply as 'chrome'), but its largest use is as an ingredient in stainless steels. Both applications benefit from chromium's hardness, resistance to corrosion and ability to be polished for a lustrous appearance.

Metal Profile: Manganese

What is manganese? Manganese is a key component in the production of steel. Although classified as a minor metal, the quantity of manganese produced worldwide each year falls behind only iron, aluminum, copper and zinc.

Base Metals

The term 'base metals' commonly refers to the industrial, non-ferrous metals: copper, lead, nickel and zinc.

Rare Earth Elements (REEs)

Until fairly recently, the lanthanide - or rare earth - elements (REEs) were a little known group of industrial metals. Locked away at the bottom of the periodic table, REEs were often overlooked, perhaps due in part to their limited uses and difficult to pronounce names.

A Short History of Steel: Part I

The development of steel can be traced back 4000 years to the beginning of the Iron Age. Proving to be harder and stronger than bronze, which had previously been the most widely used metal, iron began to displace bronze in weaponry and tools.

A Short History of Steel: Part II

The growth of railroads during the 19th century in both Europe and America put great pressure on the iron industry, which still struggled with inefficient production processes. Yet steel was still unproven as a structural metal and production was slow and costly. That was until 1856, when Henry Bessemer came up with a more effective way to...

Steel History

By the 17th century, iron's properties were well understood, but increasing urbanization in Europe demanded a more versatile structural metal. And by the 19th century, the amount of iron being consumed by expanding railroads provided metallurgists with financial incentive to find a solution to iron's brittleness and inefficient production...

Steel Applications

What is steel used for? Steel is both the most widely used and most recycled metal material on earth. From stainless and high temperature steels to flat carbon products, steel's various forms and alloys offer different properties to meet a wide range of applications. For these reasons, as well as the metal's combination of high strength and a...

Metal Profile: Bismuth

What is bismuth? Bismuth is a silvery and brittle metal that is frequently found in low-melt alloys. Demand for bismuth metal has grown over the past 20 years in large part due to its effective use as a substitute for lead.

Metal Profile: Steel

What is steel?

Steel Grades

According to the World Steel Association, there are over 3,500 different grades of steel, encompassing unique physical, chemical and environmental properties. In essence, steel is composed of iron and carbon, although it is the amount of carbon, as well as the level of impurities and additional alloying elements that determines the properties of...
