Raw Materials

Steel

Strong, machinable, and weldable—all with material certificates for traceability

Aluminum

Lightweight, easy to machine, and corrosion resistant—all with material certificates for traceability

Stainless Steel

Stainless Steel

Resists corrosion and chemicals in most environments—all with material certificates for traceability

Plastic

A lightweight alternative to metal and glass

Rubber

Nickel

An upgrade from stainless steel to withstand harsh chemicals and acids—all with material certificates for traceability

Titanium

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

Wood

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

Tin

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

Aramid

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

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

Hard Fiber

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

Carbon

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

Graphite

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

Niobium

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