Once more expensive than gold, aluminum has not lost its value over the years, only its price tag. Thanks to revolutionary methods of production largely developed in the late 1800s, the price of aluminum dropped from $34 an ounce in 1852 ($1,276 in 2022 dollars) to just $0.09 an ounce today. As a low-density, high-strength, corrosion-resistant metal, aluminum's usefulness has led to incredible consumption in many industries from transportation to packaging.

Most iron products these days are improved with the addition of ferroalloys, or iron alloys containing high levels of other primary elements. Ferroalloys are everywhere from cast iron to stainless steel. These extra elements help strengthen the metal by adding their own characteristics: silicon is used to deoxidize steel, manganese mitigates harmful effects of sulfur, and chromium increases corrosion resistance, to name just a few. But adding to iron is not without risk; if unwanted elements are part of the ferroalloy, they can weaken the resulting products.

What happens when you put two fantastic scientific minds together? Fantastic scientific breakthroughs! Dr Kim Marshall from LECO and Dr Arne Bengtson from Swerim, in Sweden, sat down with Andrew Storey, LECO Field Sales Specialist for Materials Analysis and Measured Science podcast host, to talk about their collaborative work with atomic spectroscopy and where this technology is going.

Portland cement, one of the most ubiquitous building materials in the world, is not all the same. There are five standardized types of Portland cement classified by the ASTM C150 standard, and each of these different types have different best-use cases. Part of what distinguishes these types of cement is the concentrations of carbon and sulfur in the precursor materials. Sulfur is especially important in determining the final chemical resistances of the Portland cement, so knowing the sulfur concentration is critical to correctly determining the type and quality of the final material.

Elements Newsletter recently published an infographic of all of the metals mined from the earth in 2019, and the numbers were staggering. 3,248,814,334 tons of metal were mined, of which 3,040,000,000 tons were iron ore. Nearly 94% of all of the metal mined in 2019 was iron, and nearly that percent of the iron has been, in some way, touched by LECO.

No matter where you are in the urban landscape, you are never more than a few feet from cement. Cement forms the basis of virtually the entire world’s infrastructure. It is an impressively cheap binder that enables a wide variety of building materials. Despite its ubiquity, it is a surprisingly complex mixture of a balance of ingredients such as lime, silica, alumina and more. Knowing what is in your cement is a fundamental check of its quality and strength.

May 28, 2021
For decades, LECO's supply catalogs have gone hand-in-hand with the instruments they support. With everything from consumables to accessories to spare parts, the catalogs are key additions to a LECO laboratory. The newest catalog updates for our analytical products have reformatted these workhorses to make them even more useful than ever before.
