About Composites

Easy-to-Machine 303 Stainless Steel

Widely used for fabricating fittings and fasteners, 303 stainless steel machines quickly without sticking to cutting tools.

Vinyl-Coated Lead Rods

The vinyl coating prevents lead from leaving marks on surfaces.

Composites

Arc-Resistant GPO3 Fiberglass Rods

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

Multipurpose Flame-Retardant Garolite G-10/FR4 Rods

A good all-around choice, Garolite G-10/FR4 is strong, machinable, and electrically insulating. It meets UL 94 V-0 for flame retardance.

Multipurpose Flame-Retardant Garolite G-10/FR4 Discs

A good all-around choice, Garolite G-10/FR4 is strong, machinable, and electrically insulating. It meets UL 94 V-0 for flame retardance.

High-Temperature Garolite G-11 Rods

Offering higher strength and better heat resistance than Garolite G-10/FR4, Garolite G-11 is suitable for continuous use in elevated temperatures.

Economical Garolite CE Rods

Garolite CE is often fabricated into parts where high strength is not required.

Economical Electrical-Insulating Garolite XX Rods

Stronger than Garolite CE with better electrical-insulating properties, Garolite XX is often fabricated into low-cost electrical components.

Ultra-High-Temperature
Arc-Resistant Garolite G-7 Rods

Choose these Garolite G-7 rods for their high heat tolerance—they withstand temperatures up to 425° F. While not as strong as Garolite G-9, they offer better arc resistance in dry environments.

Easy-to-Machine Garolite LE Rods

Using nothing more than standard high-speed steel tooling, Garolite LE can be machined into intricate parts.

Arc-Resistant Garolite G-9 Rods

Frequently called electrical-grade Garolite, this Garolite G-9 is strong, electrically insulating, and arc resistant in dry environments.

Halogen-Free Garolite G-10 Rods

Use Garolite G-10 in place of Garolite G-10/FR4 for applications that are sensitive to halogen, such as in nuclear plants. It's strong, machinable, and electrically insulating.

Ultra-Strength Lightweight Carbon Fiber Rods

Reinforce structures with these rods—they weigh less than aluminum while remaining strong and almost as rigid.

Easy-to-Machine Hard Fiber Rods

Hard fiber is the easiest composite to machine, making it good for creating custom parts. Also known as vulcanized fiber.
