Raw Materials

Stainless Steel

Stainless Steel

Resists corrosion and chemicals in most environments

Aluminum

Lightweight, easy to machine, and corrosion resistant in wet environments

Plastic

A lightweight alternative to metal and glass

Steel

Strong, machinable, and weldable but lacks corrosion resistance

Copper

The most conductive of our metals, it excels in all types of electrical applications

Brass

More machinable than copper and bronze for making nuts, hinges, and locks

Garolite

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

Bronze

With better wear resistance than copper and brass, it’s used for bearings, gears, and pump parts

Nickel

An upgrade from stainless steel that withstands harsh chemicals and acids at high temperatures

Titanium

The most corrosion-resistant metal we offer, with very high strength relative to its weight

Carbon Fiber

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

Fiberglass

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

Lead

A dense insulator often used to shield against radiation and absorb sound and vibration

Hard Fiber

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

Kevlar

Super tough for protection against prolonged wear and abrasion

Cobalt

Slides against other materials without wearing and sticking; resists impact and rapid temperature changes

Niobium

Conductive, corrosion resistant, and strong, even at extremely high and low temperatures
