Raw Materials

Steel

Strong, machinable, and weldable but lacks corrosion resistance

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

Brass

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

Copper

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

Garolite

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

Bronze

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

Fiberglass

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

Titanium

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

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

Ceramic

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

Nickel

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

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

Carbon Fiber

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

Glass

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

Hard Fiber

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

Foam

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

Zinc

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

Molybdenum

Retains its shape and strength in extreme temperatures and conducts heat and electricity

Cobalt

Slides against other materials without wearing and sticking; resists impact and rapid temperature changes

Power Transmission

Shafts

Transmit power, motion, and speed between machine components

Lead Screws and Nuts

Lead Screws and Nuts

Components travel along a screw with broad, square threads to clamp and lift heavy loads

Ball Screws and Nuts

Ball Screws and Nuts

Internal ball bearings roll on screws for low friction when moving components at high speeds

Sealing

Backer Rods

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

Fastening and Joining

Dowel Pins

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

Stick Electrodes

Stick Electrodes

Flux coated for stability and speed when welding most metals

Fluid Handling

Corrosion-Inhibiting Rods and Pads

Corrosion-Inhibiting Rods and Pads

Protect tanks, water heaters, and heat exchangers from rust; also known as sacrificial anodes

Mixer Shafts

Replace the shaft on mixers

Electrical

Grounding Rods

Link an electrical system to a ground
