How can we improve?

1,882 Products

Raw Materials

Garolite

A strong, machinable alternative to metal and plastic widely used in circuit boards and gears

Wood

Commonly used to build ramps, crates, and prototypes or to make repairs

Fiberglass

A lightweight alternative to metal and wood widely used in electrical and structural applications

Plastic

A lightweight alternative to metal and glass

Carbon Fiber

The strongest composite we offer; comparable in strength to 6061 aluminum but lighter in weight

Kevlar

Super tough for protection against prolonged wear and abrasion

Hard Fiber

Chemically treated to be hard and dense, this is the easiest composite to machine in our offering

Aramid

Strong, lightweight, and an excellent thermal insulator; also known as Nomex

Aluminum

Lightweight, easy to machine, and corrosion resistant—all with material certificates for traceability
