27,130 Products

Raw Materials

Steel

Strong, machinable, and weldable but lacks corrosion resistance

Stainless Steel

Stainless Steel

Resists corrosion and chemicals in most environments

Aluminum

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

Plastic

A lightweight alternative to metal and glass

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

Bronze

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

Foam

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

Garolite

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

Glass

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

Tungsten

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

Rubber

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

Titanium

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

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

Aramid

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

Nickel

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

Ceramic

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

Wood

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

Lead

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

Kevlar

Super tough for protection against prolonged wear and abrasion

Carbon

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

Felt

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

Graphite

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

Cobalt

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

Zinc

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

Mica

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

Platinum

Conductive and formable, it resists extreme heat for use in parts such as thermocouple probes

Hard Fiber

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

Tantalum

Conductive with a higher melting point than most metals, it’s often used in heating elements

Tin

Soft and malleable for forming gaskets and filters; also mixes with other metals to make solder

Molybdenum

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

Niobium

Conductive, corrosion resistant, and strong, even at extremely high and low temperatures

Fabricating and Machining

Pry Bars

Slide under heavy objects to pry, lift, and position them

Dovetail Blanks

Dovetail Blanks

Machine a blank workpiece with precut dovetails and locating slots for easy setup

Multitools

A variety of tools and blades all in one

Fluid Handling

Sintered Filters

Sintered Filters

Tiny holes let particles such as air, gas, and vapor pass through while trapping contaminants
