Easy-to-Form Pure 1000 Series
Aluminum Sheets and Bars

Made of 1000 series aluminum which is 99% pure, this aluminum offers superior formability, corrosion resistance, and electrical conductivity. It's frequently fabricated into raceways, decorative trim, and other parts where strength and hardness are not required.

Hardened Multipurpose 304 Stainless Steel

Harder than our other 304 stainless steel, these thin sheets offer better wear resistance for use as a wrap, liner, or cover.

Fatigue-Resistant 301 Stainless Steel

Able to withstand repeated stress and wear, 301 stainless steel has the strength required for applications such as springs and fasteners.

Hardened Corrosion-Resistant 316 Stainless Steel

Because these thin sheets are harder than our other 316 stainless steel, they offer better wear resistance. Use them as a wrap, liner, or cover.

High-Strength 17-4 PH Stainless Steel

With a higher chromium content than 15-5 PH stainless steel, this high-strength 17-4 PH offers better corrosion resistance. It is also known as 630 stainless steel.

Low-Carbon Steel Sheets and Bars

Also known as mild steel, low-carbon steel is easy to machine, form, and weld. It's widely fabricated into parts that don’t require high strength.

Wear-Resistant 1095 Spring Steel Sheets and Strips

Also known as blue-tempered steel.

EMI-Shielding Nickel Alloy

Use this nickel-iron-cobalt alloy as a magnetic shield to protect electronic equipment from EMI/RFI interference.

Gold Foil

Since it’s thin and easy to cut, as well as highly conductive and corrosion resistant, this 99.99% pure gold foil is often used to plate electrical connectors that are exposed to the air.

Shims

Shim Stock

Cut this stock into custom shapes to fit your application.

Adhesive-Back Shim Stock

A durable acrylic adhesive keeps this shim stock from sliding out of place. Cut it into custom shapes to fit your application.

Shim Tape

Level dies, plates, presses, and other machine tools—this shim tape conforms to curves and uneven surfaces.

Color-Coded Shim Stock

This shim stock is color coded by thickness for easy identification. Cut it into custom shapes to fit your application.

Ring Shims

Precisely align, level, and adjust spacing on fasteners and shafts with these shims.

Tight-Fit Ring Shims

For a snug fit around a shaft, the ID of these shims is held to a tighter tolerance than other round shims.

Color-Coded Ring Shims

Precisely align, level, and adjust spacing on fasteners, shafts, and machinery with these shims, which are color-coded by thickness for easy identification.

Shims for Keyed Shafts

Precisely shaped to fit snugly on keyed shafts, these shims align, level, and space components. Because of their tight fit, they also help components rotate in unison with the shaft.

Slotted Shims

The slot lets you insert, remove, and adjust the shims without disassembling your machinery.

Made-to-Order Shims

Send us a drawing, and we'll cut your custom shim.

Single-Wave Washers

These curved, flexible washers act like springs to compensate for tolerance variations and uneven surfaces.

Plastic

Slippery UHMW Polyethylene Film

In addition to a low-friction surface that prevents sticking and binding, this tough material is impact and wear resistant to handle the scuffs, scrapes, and strikes that other plastics can’t.

Moisture-Resistant Polyethylene (HDPE) Film

Practically nonabsorbent, HDPE won't swell when exposed to moisture. It is denser and more rigid than LDPE, plus it's more chemical resistant.

Flexible Polyethylene (LDPE) Film

Often used for packaging and construction applications, this film is also known as Visqueen.

Clear Chemical-Resistant PVC Film

Because PVC resists acids and alkalies, it is often used in tanks and chemical-processing applications where visibility is essential.

Clear Moisture-Resistant Polyester Film

Polyester absorbs almost no moisture and resists swelling in wet environments. It is also known as PET and PETE.

Clear Static-Dissipative
Moisture-Resistant Polyester Film

A static-dissipative coating on this polyester film prevents electrostatic discharge from damaging sensitive electronic equipment.

Glass, Mica, Ceramic, and Graphite

Flexible Very High-Temperature
Electrical-Insulating Mica Sheets

Use for wrap-around insulation.

Electrical-Insulating Mica Sheets

These mica sheets resist temperatures up to 930° F. Also called muscovite mica.

Flexible Electrical-Insulating Mica

Use for wrap-around insulation.

Clear Electrical-Insulating Mica

An excellent electrical insulator, use this mica as see-through insulation. It's also known as muscovite mica.

Super-Flexible Corning® Willow® Glass

This glass bends like plastic but is eight times harder—it’s harder than tooth enamel but softer than quartz.

Waterproof Tarps

Keep covered items dry with these UV-resistant tarps.

Stretch Wrap and Protective Fill

General Purpose Paper Rolls

This paper is good as an outer wrap for parcels or as packing fill. Also known as kraft paper.

Wax Paper Sheets

Treated with wax, these paper sheets resist tearing and have a slippery surface that protects products and foods from scratches or sticking together during manufacturing, shipping, and storing. Use them to wrap your items or even as a nonstick work surface.

General Purpose Paper Sheets

This paper is good as an outer wrap for parcels or as packing fill. Also known as kraft paper.

Corrosion-Inhibiting Wrap

Shield iron, steel, stainless steel and tin from corrosion.

Tarnish-Inhibiting Wrap

Protect silver- and gold-plated electronic components from tarnish.

Curved Disc Springs

Use these high-carbon steel springs in noncorrosive environments.

Signs, Labels, and Tags

Blank Signs

Fill in the blank with your own custom warnings, labels, and messages. You can write on these signs with markers, add color with paint, or stick on adhesive-back characters. Many even work with printers.

Write-On Accident Prevention Signs

Write a message in the blank space below the header using a permanent marker or adhesive-back characters.

Write-On Labels with Laminating Flap

Protect messages from moisture and smudging with the clear laminating flap.

Write-On Labels

Use a permanent marker to write your message.

Write-On Labels for Hot and Cold Surfaces

The adhesive on these labels withstands temperatures from -320° to 300° F. Stick them to plastic, glass, and metal surfaces.

Printer Labels for Clean Rooms

These labels peel off easily when they're no longer needed.

Thermal-Transfer Printer Labels for Clean Rooms

These labels are cleaned and double-bagged in an ISO Class 4 (Fed. Std. Class 10) clean room. Use them with a thermal-transfer printer for smudeproof results, or write on them using clean room pens.
