28,958 Products

Raw Materials

Steel

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

Aluminum

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

Stainless Steel

Stainless Steel

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

Plastic

A lightweight alternative to metal and glass

Copper

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

Brass

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

Bronze

Better wear resistance than copper and brass—all with material certificates for traceability

Garolite

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

Rubber

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

Tungsten

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

Foam

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

Titanium

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

Ceramic

Hard and wear resistant, it also withstands corrosion and high temperatures

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

Nickel

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

Wood

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

Graphite

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

Lead

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

Glass

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

Felt

Thicker and more absorbent than fabric for insulating, polishing, cushioning, and gasketing

Molybdenum

Retains its shape and strength in extreme temperatures—all with material certificates for traceability

Kevlar

Super tough for protection against prolonged wear and abrasion

Carbon

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

Cobalt

Resists impact and rapid temperature changes—all with material certificates for traceability

Zinc

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

Hard Fiber

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

Mica

An electrical insulator that resists high temperatures; use in circuit breakers and heating elements

Tantalum

Conductive with a higher melting point than most metals—all with material certificates for traceability

Niobium

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

Fastening and Joining

Magnets

Attract or repel metal objects to hang, secure, or position them

Electromagnets

Place on flat metal surfaces and turn on the power to create a magnetic hold

Machine Key Stock

Machine Key Stock

Cut a custom length to transfer torque from shafts to components such as gears and sprockets

Dowel Pin Stock

Dowel Pin Stock

Cut to the length you need for positioning and holding parts in place

Dowel Pins

Align parts before assembly or use as a pivot, shaft, or hinge to join moving components

Solder

Join pieces of metal without melting the base material

Power Transmission

Shafts

Transmit power, motion, and speed between machine components

Shaft Supports

Support linear motion shafts to prevent bending and rolling under loads

Fabricating and Machining

Casting Metals

Melt and pour into molds to make metal parts and prototypes

Prototyping Foam

Prototyping Foam

Carve, mill, or sand into lightweight parts for testing

Fluid Handling

Pipe and Pipe Fittings

Pipe and Pipe Fittings

Generally thicker and more rigid than tubing for distributing liquids and gases through your facility
