About Aluminum

Low-Carbon Steel 90° Angles

Also known as mild steel, low-carbon steel is easy to machine, form, and weld. It's widely fabricated into parts that don’t require high strength.

Zinc-Galvanized Low-Carbon Steel 90° Angles

These 90° angles are zinc galvanized for good corrosion resistance.

Multipurpose 6061 Aluminum 90° Angles

The most widely used aluminum, 6061 is fabricated into everything from pipe fittings and containers to automotive and aerospace parts. It is strong and corrosion resistant, plus it's easy to machine and weld.

Polished Multipurpose 6061 Aluminum 90° Angles

The outside of these 90° angles is polished to either a brushed finish or a mirror-like finish.

Anodized Multipurpose 6061 Aluminum 90° Angles

An anodized coating forms a bond with the aluminum surface to improve wear and corrosion resistance.

Anodized Architectural 6063 Aluminum 90° Angles

The anodized coating on these 90° angles forms a bond with the aluminum surface to improve wear and corrosion resistance.

Architectural 6063 Aluminum 90° Angles

More corrosion resistant and easier to form than multipurpose 6061 aluminum, 6063 is primarily used for exterior railings, decorative trim, and door frames.

Easy-to-Form 6060 Aluminum

Easier to bend and shape than 6061 aluminum, this aluminum is good for framing, cross sections, and structures in construction and marine industries.

High-Strength 2024 Aluminum 90° Angles

While 2024 aluminum was initially designed for structural components in aircraft, it's now widely used when a high strength-to-weight ratio is needed. It offers similar performance to 7075 aluminum, but it’s not as strong.

High-Strength 7075 Aluminum 90° Angles

Originally developed for aircraft frames, uses for 7075 aluminum now include a wide range of high-stress parts. It is often used as a replacement for 2024 aluminum because it’s stronger and provides similar performance in all other aspects.

Easy-to-Form Marine-Grade
5086 Aluminum 90° Angles

5086 aluminum is used on ships, oil rigs, tanks, and pressure vessels because of its excellent saltwater resistance and formability.

Multipurpose 304 Stainless Steel

From cookware to chemical-processing equipment, 304 stainless steel is a good all-around choice for a wide range of applications.

Corrosion-Resistant 316 Stainless Steel

The addition of molybdenum gives 316 stainless steel excellent corrosion resistance. Use it in a variety of marine and chemical-processing applications.

Composites

Structural FRP Fiberglass 90° Angles

An alternative to wood in structural applications, FRP fiberglass is strong and lightweight.

Arc-Resistant GPO3 Fiberglass 90° Angles

Offering excellent arc and track resistance, this GPO3 fiberglass is often used for electrical applications in humid environments.

Flame-Retardant FRP Fiberglass 90° Angles

Made with a flame-retardant resin, this FRP fiberglass meets ASTM E84 Class A.

Ultra-Strength Lightweight Carbon Fiber 90° Angles

Lighter than aluminum while remaining rigid, these angles are often used as brackets in structural framing, machinery, and robotics.

Multipurpose Flame-Retardant
Garolite G-10/FR4 Angles

A good all-around choice, Garolite G-10/FR4 is strong, machinable, and electrically insulating. It meets UL 94V0 for flame retardance.

Arc-Resistant Garolite G-9 Angles

Machine these angles into arc barriers, switch mounts, and components for circuit breakers and electrical equipment. They resist carrying electric currents in dry or humid areas, even when exposed to sudden electric discharge.
