Alloy Castings | Interesting Tantalum History and Facts

You have your basic metals and alloys – titanium, stainless steel, aluminum and more. And they’re great! But, behind the classics, are some renowned metals and alloys with properties that ensure the integrity of alloy castings. Tantalum is one of those materials.

History of Tantalum

Scientist found tantalum in 1802 in Sweden. It was originally thought that columbium (now niobium) and tantalum were the same. But, scientists were able to dispute that later. The first metallic form of tantalum came about in 1864. Then, in the early 1900s, it was used to create light bulb filaments and would later be replaced by tungsten.

Physical Properties

Tantalum is a dark blue-gray in color. What’s great about it in terms of metalwork is that it is dense and very hard. But workers can still fabricate it easily. It’s ductility also makes it a great component to conduct heat and electricity. However, it’s greatest physical proper is that it is extremely resistant to corrosion by acids.

Where Does It Come From?

There are several types of tantalum out there. But, not all are great for industrial purposes. The majority of tantalum comes from Australia. But, there are also mines in Thailand and Malaysia. Industry experts predict that there are less than 50 years-worth of tantalum left in the world. This is encouraging people to recycle.
