We Are Noble6 – The Noble6 Difference

What We Believe In

We don’t believe in following industry standards—we’re raising the bar to set better ones. All our offerings are based on transparency, trust, fair dealing, and expert insight. Our goal is to build long-term relationships with our partners. Because we’re more than metal refiners, we are thought leaders, leading you towards a noble difference.

Noble6 believes in demystifying the automotive precious metal recycling industry. We take pride in this approach since, within the industry of catalytic converters, oxygen sensors, and even spark plug recycling, there is a lot of misinformation out there. Especially within the catalytic converter recycling space, there are many entities that operate in a non-transparent way.

Buyers and sellers alike deserve more information about the process of doing business in this industry. We at Noble6 offer extensive educational content in the form of blogs, podcasts, and social posts. We do this because there are so many questions that go unanswered. For example, how can you determine that you are getting the best price for your converter when recycling? We outline the answer for you, provide many more additional answers, and even offer a free online tool that can get you started.

The Features That Make Noble6 Stand Out

Our main differentiator is our catalytic converter price guide. We spent years developing this incredible online software, with the first beta version being released nearly a decade ago. Not only have we accumulated more part numbers since then, but we’ve also listened to your feedback. Our most recent version has been upgraded to better meet your needs, and now includes all the necessary information for buying and selling converters. We put money into research and development to figure out what you’d want from a converter price guide, and then added more features to make your life easier. Our price guide makes it easy to grow your business, whether you’re buying or selling, with thousands of part numbers, pictures, an awesome user experience, and many other unique features. The best part is that you can access a free version. While the number of converter searches per day is limited, it is an excellent resource for newcomers to the industry or veterans who want to try it out.

Many automotive repair shop owners who acquire catalytic converters, oxygen sensors, and spark plugs benefit from our automotive recycling program. We can take all your scrap materials and turn them into profit.  As far as we can tell, Noble6 is the ONLY spark plug recycler that pays you for used spark plugs. Of course, the spark plugs must come in a package with oxygen sensors and catalytic converters to make this a viable commodity on both sides. The beauty of this is that you profit from a discarded item, and the platinum and iridium are recycled properly, helping to make a difference on a global scale.

We’re not finished yet. We also have plenty of new innovations in the pipeline for the automotive precious metals recycling industry, which we can’t wait to share with you. We’re more than metal refiners; we’re thought leaders who will guide you to a noble difference.
