See Why Alumicolor Tools Stand Out

Alumicolor Company manufactures top-quality measuring tools made from strong, smooth aluminum. Their rulers and aluminum drafting scales are crafted in El Salvador and shipped from the U.S. What makes these Alumicolor tools unique is their photo anodizing process—it locks in the markings, so they don’t rub off, even with heavy use or cleaning. You won’t feel bumps or grooves, ensuring your lines stay clean and precise. Whether you're sketching or cutting, Alumicolor products deliver dependable results every time.

Your Go-To Alumicolor Triangle

Alumicolor uses tough, tempered aluminum to make triangles that outlast typical plastic ones. Thanks to their photo anodized finish, the markings are built into the surface and won't fade—even with frequent use. The smooth surface won’t scratch your paper, making these triangles ideal for precision work. Choose from popular sizes like 6” to 14”, and standard angles like 30/60 and 45/90. Many models now include markings around the holes for added ease. You can even purchase value sets that combine the most-used tools—perfect for beginners or pros looking to upgrade their Alumicolor tools collection.

At Engineer Supply, we're committed to making your job easier with top-quality Alumicolor tools. From aluminum drafting scales to precision rulers and triangles, Alumicolor products come in various sizes and colors to help you measure, draw, and cut with ease.

Frequently Asked Questions

Are Alumicolor triangles better than plastic ones?

Yes, they are! Alumicolor triangles are made of tempered aluminum, so they’re much tougher and last a lot longer than plastic triangles. They don’t warp or crack, and the markings won’t rub off even after years of use.

Do the markings on Alumicolor tools fade over time?

No, the markings are part of the metal itself through something called photo anodizing. That means they won’t fade, scratch, or rub off easily—even if you clean them often.

Can I get metric and inch measurements on Alumicolor triangles?

Yes! Most Alumicolor triangles have both inches and centimeters printed on them, which is super handy if you work with both systems.

Do Alumicolor triangles scratch paper?

Not at all. The finish is very smooth, so it won’t scratch or leave marks on your paper or work surface. That’s why they’re a favorite among students and professionals.

Can I use Alumicolor tools for cutting?

Some Alumicolor products, like the AlumiCutter and AlumiCrafter, are made for cutting. They work well with craft knives and are safe to use as straight edges for trimming paper or photos.

How do I clean Alumicolor tools?

Just wipe them gently with a soft cloth. No need for harsh cleaners—since the markings are part of the finish, they won’t come off with normal cleaning.
