Raw Materials

Steel

Strong, machinable, and weldable but lacks corrosion resistance

Aluminum

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

Stainless Steel

Stainless Steel

Resists corrosion and chemicals in most 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

Bronze

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

Titanium

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

Tungsten

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

Nickel

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

Lead

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

Gold

Softer than copper and nearly as conductive, form it into electronic components that won't corrode

Additives and Fillers

Additives and Fillers

Mix into coatings, resins, polymers, and metal to boost strength, conductivity, and lubricity

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

Plastic

A lightweight alternative to metal and glass

Tin

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

Platinum

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

Gallium

Transfers heat and electricity as a safe alternative to mercury in thermometers and thermostats

Tantalum

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

Niobium

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