Sleek. Strong. Reliable.

When precision, appearance, and corrosion resistance all matter, 6063-T5 delivers.

Often called “the architectural alloy,” 6063-T5 aluminum provides the smooth, consistent finish required for visible applications — window frames, curtain wall systems, handrails, and decorative trims. It’s the alloy of choice when you want your design to look as good in ten years as it does on day one.

At Aluminum Supply Company (ASCO), we stock and source a wide range of 6063-T5 extrusions in the most in-demand shapes and dimensions. Our inventory is geared for short lead times, and our team understands the details that make installation simple — precise lengths, consistent tolerances, and finishes that hold up under real-world conditions.

We’re not a mill. We’re your connection to the best extrusion mills in the country, backed by 75 years of local Detroit experience in cutting, finishing, and fabricating metal the right way. When you order from ASCO, you get more than aluminum — you get partnership, responsiveness, and work that speaks for itself.

Many profiles are available anodized or mill finish, cut-to-length, and ready for fabrication.

Solids

Precision-drawn 6063-T5 aluminum round rods provide an excellent balance of strength, machinability, and finish quality. Commonly used for pins, spacers, standoffs, and decorative components, they polish and anodize beautifully, making them ideal for both architectural detailing and mechanical assemblies.

Common Applications: Hardware components, standoffs, decorative rods, dowels, fixtures.

6063-T5 square bar offers uniform dimensions and excellent surface quality for projects requiring clean geometry and a refined look. Easily machined and anodized, this alloy is well-suited for trim, architectural accents, and custom fabrication.

Common Applications: Framing, posts, decorative elements, furniture fabrication.

This multipurpose bar stock delivers consistent flatness and straightness for architectural and fabrication use. Its smooth finish and high corrosion resistance make it ideal for visible assemblies and precision frameworks.

Common Applications: Mounting plates, brackets, trim strips, signage structures.
