| ABS |
Engineering Plastic |
ABS (acrylonitrile-butadiene-styrene) plastics are tough and resist impact well across their temperature range. |
| Arcylic |
Engineering Plastic |
This strong, stable material has excellent optical clarity and good tensile strength. Acrylics are generally very
weather resistant. |
| Fluoropolymers |
Engineering Plastic |
These materials are tough yet easy to machine. Fluoropolymers generally have very slippery surfaces. |
| Nylon |
Engineering Plastic |
Nylons typically resist chemical corrosion and have a slippery surface. |
| PEEK |
Engineering Plastic |
PEEK (polyetheretherketone) maintains its shape across its temperature range better than Teflon® and has
greater tensile strength. Common applications include pump and valve parts and chemical processing. |
| Polycarbonate |
Engineering Plastic |
Most polycarbonates are very strong and have excellent optical clarity. Clear polycarbonates have glasslike
clarity but have 10 times the impact strength of any other clear plastic. |
| Polyetherimide |
Engineering Plastic |
Also known by the tradename Ultem, this plastic offers high strength and rigidity, along with good chemical
resistance. It is used in a variety of structural applications requiring strength and electrical insulation at
higher temperatures. |
| Aluminum |
Engineering Alloy |
Aluminum alloys are strong, naturally soft, lightweight, ductile and malleable. They are easy to machine,
fabricate, join and work. Aluminum is nontoxic and electrically and thermally conductive. |
| Brass |
Engineering Alloy |
Brass resists atmospheric corrosion, water, and many salt water solutions. A high percentage of zinc makes
it stronger and more durable than copper and bronze. |
| Stainless Steel |
Engineering Alloy |
Stainless steels are alloys of iron to which at least 10% chromium has been added to impart corrosion resistance.
A 10% chromium steel will not rust when exposed to weather. To obtain greater corrosion resistance, more
nickel and chromium are added to the alloy. Along with iron and chromium, all stainless steels contain some
carbon. The carbon is added for the same purpose as in ordinary steels- to make steel stronger. Other alloying
elements are added for improved corrosion resistance, fabricability and variations in strength. These elements
include nickel, molybdenum, copper, titanium, silicone, aluminum, sulfur and many others. |
| Steel |
Engineering Alloy |
Steel is iron that has been combined with other elements such as carbon, manganese and silicon. It falls
into one of two families: carbon steel or alloy steel. Carbon steels are basic steels which harden only with
surface (case) treatments. Alloy steels contain added elements that cause the steel to exhibit enhanced
properties when heat treated. |
