Below are some of the materials & their attributes (not a complete list) that we work with. Our experience may be able to help you with your engineering decisions.
Acetal (the generic name for a family of products) provides
high strength and stiffness along with increased dimensional
stability and ease of machining. Low moisture absorption,
low coefficient of friction as well as good wear properties
make DELRINŽ resin ideally suited for close tolerance
mechanical parts. Lubricated and glass filled grades are
available to enhance DELRINŽ resin's already excellent
mechanical and thermal properties. DELRINŽ resin is commonly
used for gears, rollers, electrical components.
Polyetheretherketones (PEEK), also referred to as
polyketones, are obtained from aromatic dihalides and
bisphenolate salts by nucleophilic substitution.
TYPE 304 - The
most commonly specified austenitic (chromium-nickel
stainless class) stainless steel, accounting for more than
half of the stainless steel produced in the world. This
grade withstands ordinary corrosion in architecture, is
durable in typical food processing environments, and resists
most chemicals. Type 304 is available in virtually all
product forms and finishes.
Precipitation hardening stainless steels are chromium-nickel alloys. Precipitation-hardening stainless steels may be either austenitic or martensitic in the annealed condition. In most cases, precipitation hardening stainless steels attain high strength by precipitation hardening of the martensitic structure.
Selecting a Stainless Steel
There are a large number of stainless steels produced. Corrosion resistance, physical properties, and mechanical properties are generally among the properties considered when selecting stainless steel for an application. A more detailed list of selection criteria is listed below:
Corrosion resistance is commonly the most significant characteristic of a stainless steel, but can also be the most difficult to assess for a specific application. General corrosion resistance is comparatively easy to determine, but real environments are usually more complex. An evaluation of other pertinent variables such as fluid velocity, stagnation, turbulence, galvanic couples, welds, crevices, deposits, impurities, variation in temperature, and variation from planned operating chemistry among others issues need to be factored in to selecting the proper stainless steel for a specific environment.
AluminumAluminium is a soft, lightweight metal with normally a dull silvery appearance caused by a thin layer of oxidation that forms quickly when the metal is exposed to air. Aluminium oxide has a higher melting point than pure aluminium. Aluminium is nontoxic (as the metal), nonmagnetic, and nonsparking. It has a tensile strength of about 49 megapascals (MPa) in a pure state and 400 MPa as an alloy. Aluminium is about one-third as dense as steel or copper; it is malleable, ductile, and easily machined and cast. It has excellent corrosion resistance and durability because of the protective oxide layer. Aluminium mirror finish has the highest reflectance of any metal in the 200-400 nm (UV) and the 3000-10000 nm (far IR) regions, while in the 400-700 nm visible range it is slightly outdone by silver and in the 700-3000 (near IR) by silver, gold, and copper. It is the second-most malleable metal (after gold) and the sixth-most ductile. Aluminium is a good heat conductor
Because of its high tensile strength (even at high
temperatures), light weight, extraordinary corrosion
resistance, and ability to withstand extreme temperatures,
titanium alloys are used in aircraft, armour plating, naval
ships, spacecraft, and missiles. It is used in steel alloys
to reduce grain size and as a deoxidizer, and in stainless
steel to reduce carbon content. Titanium is often alloyed
with aluminium (to refine grain size), vanadium, copper (to
harden), iron, manganese, molybdenum, and with other metals.
