Understanding Sintered and Powder Metallurgy

 What IS Sintered Metal?




Well, let's answer that question with another question, "What is the strong metal on earth?"
Titanium? Tungsten? The metal used to make the wolverine's claws?

Perhaps any and all of these are the correct answer, as scientists are still battling it out over who wins the MEDAL for the strongest METAL. What we CAN tell you, however is that the strongest metal on earth is impervious to most modern-day metallurgy techniques. That being said, let's just pretend that tungsten is the strongest of all. A lot of companies have begun using it as a precious metal out of which to make jewelry, such as rings.

So, how exactly would a company go about making that ring? Do they simply throw it in a pot and melt it down to start forging into a circle? Yes and no. Fact of the matter is, tungsten, being one of the hardest and most durable metals in the world falls prey to the very thing that makes it so valuable: it is nearly indestructible. As such, using it for anything makes it instantly one of the more expensive metals for consumer use.

So, why is it exactly that metals like this are so difficult to work with? Well, being of incredible durability, melting it down isn't exactly an option unless you happen to have a super-oven that is hot enough to reach over 6100 degrees Fahrenheit.

For this reason, companies find themselves spending millions of dollars over the course of their firms lifetime just to operate these incredible machines capable of managing heavy metals.
Which brings in one of the latest industrial technological advances:
High temperature powder metallurgy.

At SSI Sintered, they specialize in the manufacturing of steel and other metal components through the use of powder metal sintering. What is that? Simply put, it takes the base component of powdered metal particles, brings them to near melting point temperatures, and binds the atoms together across the surface of the particles to hold it together in a much stronger fashion that of traditional metal working methods.

By utilizing this process, SSI Sintered is able to manufacture more parts per order and in a shorter period of time. Not only does the production time go down, have longer production runs, and cost less per unit, but there is close to ZERO waste as a result. The powder metal compaction process involves utilizing nearly 100% of the base material without a serious amount of loss.

Perhaps one of the most amazing features of this system is the overall quality of the product. With the economy being in a rough spot lately, a lot of firms are trying to find as many ways to slash budgets as they can. As such, often times, companies have known to drop the quality on their product to improve the bottom line.

Not SSI Sintered.
Rather, the quality of the component holds steady and gets better and better each year as technology advances to improve the sintering process. With most traditional metal working methods such as stamping, forging, and machining bringing in a theoretical density as low as 82%, SSI Sintered's technology results in a product with such high density, as high as 94%.
