Top Different Types of 7075 Aluminum Extrusions

Today, we’re diving into the world of aluminum extrusions, specifically focusing on a super cool type called 7075 aluminum extrusions. But don’t worry, we won’t be throwing any fancy jargon your way. We’re keeping it simple, just like chatting with a friend. So, let’s get started!

What Are Aluminum Extrusions?

First things first, let’s talk about what aluminum extrusions are. Imagine playing with playdough and squeezing it through a star-shaped mold to create long, star-shaped strings. That’s kinda what aluminum extrusion is like. It’s a process where aluminum is pushed through a mold to create long, useful shapes that can be used in lots of things like planes, cars, and even your bike.
