2,588 Products

Raw Materials

Plastic

A lightweight alternative to metal and glass

Stainless Steel

Stainless Steel

Resists corrosion and chemicals in most environments

Aluminum

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

Steel

Strong, machinable, and weldable but lacks corrosion resistance

Fiberglass

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

Rubber

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

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

Foam

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

Ceramic

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

Felt

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

Brass

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

Titanium

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

Copper

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

Bronze

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

Kevlar

Super tough for protection against prolonged wear and abrasion

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

Carbon Fiber

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

Tungsten

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

Aramid

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

Lead

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

Nickel

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

Graphite

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

Mica

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

Carbon

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

Material Handling

Corrugated Sheets

Corrugated Sheets

Slide between pallets and stacked items to protect them from damage or reinforce the bottom of boxes

Heating, Ventilation, and Air Conditioning

Thermal Insulation Sheets

Thermal Insulation Sheets

Line the walls of furnaces, freezers, ductwork, and buildings to keep heat in or out

Pipe Insulation

Pipe Insulation

Fit around pipe, tubing, and tanks to reduce heat loss or condensation

Fastening and Joining

Shims

Align and space components on shafts, or level machinery, cabinets, and doors

Sealing

Gasket Material

Gasket Material

Cut custom shapes and sizes to fill gaps between flat surfaces

EMI/RFI Shielding Gaskets

EMI/RFI Shielding Gaskets

Fit around enclosure doors or data connectors to prevent inaccurate signals and flickering displays

Fluid Handling

Filter Mesh

Strain particles out of various substances

Building and Machinery Hardware

Ceiling Tiles

Create a new drop ceiling that allows access to pipes and wiring

Power Transmission

Brake and Clutch Lining

Brake and Clutch Lining

Replace the lining in brakes and clutches; also known as friction material

Lighting

Light Lenses

Reduce glare from light bulbs and protect them from damage

Safety Equipment

Acoustic Insulation

Acoustic Insulation

Absorb sound to quiet noisy areas and machines

Fabricating and Machining

Sandpaper

Add to sanders, sanding blocks, and other tools to create a smooth finish on work surfaces
