Hey guys, it's Mike Descrapper. I got a request or a few requests on how to tell the difference between stainless steel and aluminum. Alright, I'm going to show you this mug. It kind of looks like aluminum, it kind of looks like stainless steel. Put a magnet, doesn't stick to the magnet. Got a piece here, another piece. Again, doesn't stick. How can you tell the difference between these two? Here's a knife. It sticks. Now I'm going to show you what's the difference, how to tell the difference between stainless steel and aluminum. With a grinder. Hey, if you have one of these grinders, perfect. You know a place that has a shop that has one of these if you don't have one. This is how you test aluminum. This is how you test stainless steel. Now I'm going to turn it on. I might have to yell a little bit. Alright, we're going to use the mug. We're going to put the mug here. See those sparks? That's steel. Okay, that shows you right there. That stainless steel. See this little piece right here? No sparks? That's aluminum. Alright? Tonight. Remember the knife that was magnetic? That's steel. Alright guys, that's one of the easiest ways to tell if something's aluminum or stainless steel. See that? So the sparks? But it doesn't track to the magnet. That's because this is non-magnetic stainless steel. They add nickel and I think it's chromium to the metal to make it non-magnetic. This is why it's worth more money in your scrap yard. So if you have non-magnetic stainless steel, take it to your scrap yard and separate it from your regular steel. They'll give you more money for this stuff. Alright? Except for the knife. See the knife? They'll just throw this in your steel pile. Alright? And then you have your piece of aluminum. Alright? That's how you can tell the difference between stainless steel and aluminum.
