At Critical Laser, one of the most important steps in any custom fabrication project is deciding which material to use. Each type of metal has its own strengths, appearance, and performance qualities—and the right choice can make all the difference.
If you’re not familiar with metals, don’t worry. We’ll walk you through the most common options we work with and explain what makes each unique.
Why Work With Critical Laser?
For over 25 years, Critical Laser has been Utah’s trusted partner in custom metal fabrication. From our shop in Lindon, we’ve worked with everyone from large manufacturers to small businesses and individual creators. Our advanced equipment—including high-speed fiber lasers and precision bending machines—gives us the ability to deliver both one-off custom projects and large-scale production runs with the same level of quality.
Most importantly, we don’t just cut and bend metal—we guide you through the entire process. Our team can help you decide which material best fits your project’s needs, budget, and environment, ensuring your finished product is both functional and built to last.
Mild Steel
Mild steel is one of the most widely used metals in fabrication. It’s strong, easy to weld, and cost-effective, making it a top choice for structural parts, brackets, frames, and general applications.
- Pros: Affordable, widely available, and versatile.
- Cons: Can rust if not coated or treated.
At Critical Laser, we often pair mild steel with protective coatings or finishes to extend its lifespan while keeping costs low. Learn more about mild steel here.
Stainless Steel
Stainless steel is a favorite when durability and appearance both matter. It resists corrosion and doesn’t require additional coatings, making it perfect for kitchens, medical equipment, outdoor projects, and high-end finishes.
- Pros: Corrosion-resistant, strong, and attractive with a natural shine.
- Cons: More expensive than mild steel, and heavier than aluminum.
If you’re looking for both performance and aesthetics, stainless steel is hard to beat. Check out some of our stainless steel projects here.

Aluminum
Aluminum is the go-to choice for projects where weight is a concern. It’s about one-third the weight of steel but still provides excellent strength and natural resistance to corrosion. It’s commonly used in aerospace, automotive, signage, and outdoor structures.
- Pros: Lightweight, easy to machine, and corrosion-resistant.
- Cons: Not as strong as steel for heavy structural needs.
Our precision cutting and bending equipment is well-suited for aluminum, delivering clean edges and smooth bends without warping. See how else aluminum might be the fit for you.
Brass
Brass isn’t just functional—it’s beautiful. With its signature golden color, brass is often used in decorative elements, signage, plaques, and artistic pieces. It’s also easy to machine and engrave, giving us the flexibility to create intricate designs.
- Pros: Attractive finish, good machinability, and corrosion resistance.
- Cons: Softer than steel, so not ideal for heavy-load applications.
We’ve helped clients use brass for both practical and decorative purposes, adding a touch of class and sophistication to their projects. Explore our brass projects here.

Copper
Copper combines beauty with functionality. Its reddish tone makes it stand out in decorative work, while its high conductivity makes it ideal for electrical components and specialized applications.
- Pros: Excellent conductivity, distinctive appearance, and corrosion resistance.
- Cons: More expensive than other metals and can oxidize over time (forming a green patina).
We often recommend copper for artistic pieces, custom installations, or projects that require electrical conductivity. See what’s possible with copper here.
Choosing the Right Fit
Every project is different, and the “best” metal depends on your goals. Do you need something light and easy to handle? Go with aluminum. Looking for strength on a budget? Mild steel is your friend. Want a sleek finish that lasts? Stainless steel has you covered.
That’s where our expertise comes in. At Critical Laser, we don’t just fabricate—we help you make informed decisions so your project is successful from start to finish.
