Metals and Money

Understanding the fluctuation of key indices can help you forecast and plan for your own operation. The graphs below were compiled by Air Products economists to illustrate three-year trends for utility and metals pricing as well as industrial production. We'll continue to keep you updated once a quarter.

Metal Tech: Atmosphere Plays Vital Role in Sintering Process

With increasing demands on the properties of sintered components used in the automotive industry, it is no longer sufficient to merely obtain better properties. Consistency must also be obtained.

Although many variables are considered to improve consistency, many overlook the sintering atmosphere as a variable. While most of the variables are established during the design stage of the component, the atmosphere can change during the sintering process, which ultimately influences the product's final properties and consistency. As a result, sintering atmosphere control is critical with sinter-hardenable, alloyed products.

Air Products and Surface Combustion can help optimize your sintering operation. We can analyze your operation to help you determine which atmosphere is best for your process.

To find out how you can improve your sintering atmosphere—resulting in better, more consistent properties—read this article (PDF, 529 K) or contact us.

Pulling Gases from This Air: How Cryogenic Air Separation Works

Dry air contains, by volume, 21% oxygen, 78% nitrogen, almost 1% argon, trace amounts of carbon dioxide, hydrogen, other gases, and varying amounts of water vapor and pollutants. So how does Air Products cryogenically separate out these gases to produce gas so pure that we measure impurities in parts per million? This illustration demystifies the process.

To have Air Products help you with your gas supply, contact us or call 800-654-4567, code 449. Or if you're interested in touring one of our plants near you, give us a call, or contact your local ASM chapter.

The Effects of Nitrogen—Liquid and Gaseous—on Aluminum Extrusion Productivity

As an effective inert shroud, gaseous nitrogen has been used for some time in the aluminum extrusion industry to reduce the formation of oxides on the exit side of the die bearing. Liquid nitrogen can be employed as a cooling medium as well as an inerting agent. Die cooling has been shown to lower extrusion process temperatures and contribute to increased extrusion velocities.

One can usually lower press costs and improve extrusion velocities by using either liquid nitrogen or gaseous nitrogen—especially as the relative active cycle becomes a larger portion of the total cycle (i.e., shorter dead cycle intervals, longer billets, etc.). Higher extrusion velocities have helped our customers increase production without adding lines.

For more detailed information about using gaseous and liquid nitrogen to enhance aluminum extrusion, read the full article (PDF, 4MB) or contact us.

Ask the Expert

Annemarie Weist

Annemarie Weist
Senior Principal Research Engineer



Q: Our gas quenching process uses a lot of gas and then vents it. Can we purify and reuse that gas?

A: Depending on impurities, gas volumes and ease of capture, many gases can be and are recycled. Discover how and improve your recycling today.

As seen in Industrial Heating, past "Ask the Expert" questions can be viewed at www.airproducts.com/MetalsAskTheExperts.

Learn whether you're following best practices in atmosphere supply and other operational areas by assessing your process at www.metalsassessment.com.

Send us a question. Each quarter we'll select the most challenging question to win a $100 gift certificate.
Congratulations to Elliott Frauenglass, last quarter's winner.

Meet This Quarter's Metal Head
Guido Plicht

Guido Plicht Don't be deceived if Guido Plicht appears relaxed when he's working on a heat treatment problem for a customer. Behind his tranquil appearance is a vigorous, ruminating mind.

"I'm a patient person, and in this business you need to be patient," says Plicht, European Metals Processing Commercial Technology Lead. "Solving problems is like doing research or development. You will encounter difficulties along the way. If you're not patient, you will not get results."

The Germany-based Plicht travels extensively throughout Europe helping Air Products' customers get the most out of their heat treating processes. And although he sees common issues from customer to customer, he frequently encounters new demands where his persistence and the teamwork of his colleagues come in handy.

"One customer asked us to find a way to purify his off-gas system to recycle gas. Another wanted to use liquid nitrogen to reduce rust problems on his cold rolling strip," says the 15-year Air Products veteran. "You tap your own experience and talk with others inside Air Products—for example, our Cryogenic group has expertise with liquid nitrogen. And you work closely with customers. It's a process of putting together the pieces of a puzzle.

"But we always look at problems over the long term. It allows you to see and understand the whole process. In the end, the new problems that are the most challenging are the ones that make this job fun."
