Raw Materials

Steel

Strong, machinable, and weldable—all with material certificates for traceability

Stainless Steel

Stainless Steel

Resists corrosion and chemicals in most environments—all with material certificates for traceability

Aluminum

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

Plastic

A lightweight alternative to metal and glass

Brass

More machinable than copper and bronze—all with material certificates for traceability

Fiberglass

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

Zinc

Draws corrosion away from nearby metal; an alternative to lead for sound barriers and vibration dampers

Foam

Pockets of air make it lighter in weight than rubber; good for packing, insulating, and sealing

Carbon Fiber

Compresses and bounces back to shape; often used for sealing, cushioning, and shock absorbing

Copper

Our most conductive metal for electrical applications—all with material certificates for traceability

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

Tin

Soft and malleable for forming gaskets and filters; also mixes with other metals to make solder

Carbon

An electrical conductor that’s often used in electronics and sensors

Graphite

Compressible or conductive for making high-temperature seals, furnace parts, and crucibles

Glass

Clear and highly heat and chemical resistant; often used in sights, lighting, and lab equipment

Lead

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

Titanium

The most corrosion-resistant metal we offer—all with material certificates for traceability

Hard Fiber

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

Tungsten

Our densest metal resists wear and heat to make end mills, heat shields, electrodes, and more

Nickel

An upgrade from stainless steel to withstand harsh chemicals and acids—all with material certificates for traceability

Niobium

Conductive and corrosion resistant even at extreme temperatures—all with material certificates for traceability
