Titanium

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

Garolite

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

Tungsten

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

Nickel

Glass

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

Carbon Fiber

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

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

Fiberglass

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

Graphite

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

Wood

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

Wax

Create seals and prototypes, lubricate tools, and polish equipment

Molybdenum

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

Lead

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

Cobalt

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

Gold

Form into electronic components that won't corrode—all with material certificates for traceability

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

Niobium

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

Felt

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

Mica

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

Platinum

Formable and conductive while resisting extreme heat—all with material certificates for traceability

Tantalum

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

Power Transmission

Rotary Shafts

Pair with gears, sprockets, and bearings to transmit rotary motion

Linear Shafts

Pair with linear bearings to reduce friction in manual and automated systems

Linear Shaft Supports

Linear Shaft Supports

Support linear shafts to prevent bending and rolling under loads

Sealing

Backer Rods

Insert into gaps before caulking to reduce how much sealant you need and improve adhesion

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

Tube and Tube Fittings

Tube and Tube Fittings

Typically more flexible than pipe for carrying liquids and gases in short runs around equipment

Mixer Shafts

Replace the shaft on mixers

Building and Machinery Hardware

Clamp-On Framing and Fittings

Clamp-On Framing and Fittings

Two-piece fittings let you modify assembly stations, conveyors, and racks without dismantling them

Slip-On Framing and Fittings

Slip-On Framing and Fittings

Insert rails into fittings and tighten screws to make guards, railings, and racks

Safety Equipment

Handrails

Grab while using stairs to reduce risk of falls

Facility and Grounds Maintenance

Rebar

Reinforces concrete to reduce the chance it will crack from expansion and contraction

Rebar Caps

Brightly colored to alert workers to exposed rebar and pipe

Grab Bars

Steady and support people with limited mobility in bathrooms

Material Handling

Scaffold Clamps

Scaffold Clamps

Construct scaffolding and secure supports, such as railings

Lighting

Light Pipes

Concentrate and direct light from the bulb on a circuit board to a display
