Body Material | |||
Your choices are... | |||
Acetal | Acetal polymers are semi-crystalline. They offer excellent inherent lubricity, fatigue resistance, and chemical resistance. Acetal suffers from outgassing problems at elevated temperatures, and is brittle at low temperatures. Glass filled, and added lubrication grades are available, flame-retardant grades are not. Brand names include Celcon® (Hoechst Celanese), Delrin® (DuPont), Thermocomp® (LNP), Ultraform® (BASF), and Acetron® (DSM). | ||
Aluminum | Aluminum is a bluish silver-white malleable ductile light trivalent metallic element that has good electrical and thermal conductivity, high reflectivity, and resistance to oxidation. | ||
Brass / Bronze | Brass comes with good strength, excellent high temperature ductility and reasonable cold ductility, good conductivity, excellent corrosion resistance, good bearing properties and low magnetic permeability. Sintered bronze is a porous material, which can be impregnated with oil, graphite or PTFE. Not suitable for heavily loaded applications but useful where lubrication is inconvenient. | ||
Cast Iron | The term "cast iron" refers not to a single material, but to a family of materials whose major constituent is iron, with important trace amounts of carbon and silicon. Cast irons are natural composite materials whose properties are determined by their microstructures - the stable and metastable phases formed during solidification or subsequent heat treatment. The major microstructural constituents of cast irons are: the chemical and morphological forms taken by carbon, and the continuous metal matrix in which the carbon and/or carbide are dispersed. | ||
Copper | A common reddish metallic element that is ductile and malleable and is one of the best conductors of heat and electricity. | ||
CPVC | Chlorinated polyvinyl chloride (CPC) a higher type grade of plastic commonly used for hot / cold water distribution, sprinkler piping, and some chemicals. Suitable for high temperatures. | ||
Ductile Iron | Ductile iron retains cast iron's machinability and corrosion-resistance, and provides additional strength, toughness, and ductility. Although it’s chemical properties are similar to those of cast iron, ductile iron incorporates significant casting refinements, additional metallurgical processes, and superior quality control. | ||
Exotic Metal | Exotic metals and alloys have specialized properties. This category includes materials such as Hastelloy®, Monel®, beryllium copper, beryllium nickel, niobium, tantalum, titanium and zirconium. | ||
Nylon - Polyamide | Thermoplastic resin used for mechanical parts. Can be extracted, cast or injection molded. The most common commercial grade is Nylon 6/6. Can to glass filled to further enhance structural impact strength and rigidity. | ||
PEEK | Polyetheretherketone or Polyketones. PEEK is a semi-crystalline thermoplastic with excellent mechanical properties. | ||
Polyethylene (PE) | Commodity thermoplastic that is soft, flexible and tough - even at low temperatures - with outstanding electrical properties but poor temperature resistance. It also has very good chemical resistance but is prone to environmental stress cracking; it has poor UV resistance (unless modified) and poor barrier properties, except to water. | ||
Polypropylene (PP) | Polypropylene is a thermoplastic material exhibiting excellent cold flow, bi-axial strength, and yield elongation properties. It is similar to PVC but can be used in exposed applications because of its resistance to UV, weathering, and ozone. | ||
PTFE - Teflon® | Polytetrafluoroethylene (PTFE) is an insoluble compound that exhibits a high degree of chemical resistance and a low coefficient of friction. It is sometimes marketed in proprietary classes of materials such as Teflon®, a registered trademark of DuPont Dow Elastomers. | ||
PVC | Polyvinyl Chloride (PVC) is a widely used material that has good flexibility, smooth surface, and nontoxic qualities. Some grades are used in food and chemical processes due to the inert nature of PVC. Brand names include: ACP® and Dural® (Alpha Gary), Geon® (Geon), Benvic® (Solvay), Flexalloy® (Teknor Apex). | ||
PVDF | Polyvinylidene fluoride (PVDF) is a melt processable fluoropolymer. It is similar in properties to other fluoropolymer, but has better strength and lower creep than the other members of this family. PVDF has good wear resistance, and excellent chemical resistance. But does not perform well at elevated temperatures. Brand names include: Kynar® (Elf AtoChem). | ||
Rubber | Any of several material compositions with properties similar to natural rubber. | ||
Stainless Steel | Stainless steel is chemical and corrosion resistant and can have relatively high-pressure ratings. | ||
Steel | Steel is a commercial iron that contains carbon in any amount up to about 1.7 percent as an essential alloying constituent. It is malleable when under suitable conditions, and is distinguished from cast iron by its malleability and lower carbon content. | ||
Other | Other unlisted, specialized, or proprietary material. | ||
