Developed primarily for high-strength applications, these steels are usually heat-treated alloys that provide strengths at least equal to those of as-rolled steel.
As the lightest structural metal available, magnesium's combination of low density and good mechanical strength results in a high strength-to-weight ratio.
Alkyd molding compounds are based on unsaturated polyester-type resins, which are combined with crosslinking monomers, catalysts, reinforcements, lubricants, and fillers.
Structural applications that require specific corrosion resistance or elevated temperature strength receive the necessary properties from nickel and its alloys.
Laminated plastics are a special form of polymer-matrix composite consisting of layers of reinforcing materials that have been impregnated with thermosetting resins, bonded together, and cured under heat and pressure.
Carbon steel, also called plain carbon steel, is a malleable, iron-based metal containing carbon, small amounts of manganese, and other elements that are inherently present.
Polyolefin homopolymers are made from ethylene, propylene, butylene, and methyl pentene. Other olefin monomers such as pentene and hexene are used to make copolymers.
This group includes those materials in the Class A designation (no requirement regarding volume swell due to oil) and Types A and B designations (for continuous use not exceeding 70 and 100°C).
In order to control noise, designers must first determine where the noise source or sources are how much each is contributing to the overall level, and their frequency signatures.
