Definitions

Aluminum is nonmagnetic and nonsparking and has about one-third the density and stiffness of steel. It is ductile, and easily machined, cast, and extruded. Corrosion resistance can be excellent due to a thin surface layer of aluminum oxide that forms when the metal is exposed to air, effectively preventing further corrosion.

Tool Steel refers to a variety of carbon and alloy steels that are particularly well-suited to be made into tools. Their suitability comes from their distinctive hardness, resistance to abrasion, their ability to hold a cutting edge, and/or their resistance to deformation at elevated temperatures (red-hardness). Tool steels are generally used in a heat-treated state.

300 Series Stainless Steels are austenitic grades which are nonmagnetic. The most common are iron-chromium-nickel steels, that are the most corrosion-resistant of the stainless group. They cannot be hardened by heat treatment but can be hardened significantly by cold-working.

400 Series Stainless Steels are ferritic grades developed to be resistant to corrosion and oxidation while being highly resistant to stress corrosion cracking. These steels are magnetic and can be hardened by heat treatment. They can be cold worked and softened by annealing. As a group, they are more corrosion resistant than the martensitic grades.

17-4 Precipitation Hardening Stainless Steel is also known as Type 630. It is a chromium-copper precipitation hardening stainless steel used for applications requiring strength and a moderate level of corrosion resistance. High strength is maintained to approximately 600 degrees Fahrenheit (316 degrees Celsius). It is a precipitation hardening martensitic stainless steel with mechanical properties that can be optimized with heat treatment.

Nitronic Stainless Steels are nitrogen-strengthened austenitic stainless steels that possess superior corrosion resistance, as well as roughly twice the yield strength at room temperature. Other advantages of Nitronic Stainless Steels include very good mechanical properties at both sub-zero and elevated temperatures, along with low-temperature impact resistance, as well as superb resistance to high-temperature oxidation.

Titanium has physical qualities of high strength, toughness, durability, low density, corrosion resistance and biological compatibility that make it useful in a variety of applications. It weighs forty percent less than carbon steels and can be strengthened by alloying it with elements such as aluminum and vanadium. Titanium is nonmagnetic and possesses good heat transfer properties. It has the ability to be passivated, thereby giving it a corrosion resistance to acids. It is also nontoxic and biocompatible.

PEEK is a semicrystalline thermoplastic with excellent mechanical and chemical resistance properties that are retained in high temperatures. Because of its robustness, PEEK is used to fabricate items for demanding applications, including bearings, piston parts, pumps, compressor plate valves, and cable insulation. PEEK is considered an advanced biomaterial used in medical implants. It is extensively used in the aerospace, automotive, medical, and chemical process industries.

Nylon is a generic designation for a family of synthetic polymers known generically as polyamides. Excellent abrasion resistance.

Delrin, or Polyoxymethylene (POM), is a plastic often marketed and used as a metal substitute. Delrin is a lightweight, low-friction, and wear-resistant thermoplastic with good physical and processing properties and capable of operating in temperatures in excess of 90 degrees celsius (approximately 200 degrees Fahrenheit).

Medical Device, according to the U.S. Food and Drug Administration (FDA), is an instrument, apparatus, implement, machine, contrivance, implant, in vitro reagent, or other similar or related article, including a component part, or accessory which is: intended for use in the diagnosis of disease or other conditions, or in the cure, mitigation, treatment, or prevention of disease.
Spine Instruments and Implants are used by both Neurosurgeons and Orthopedic Surgeons employing surgical means to treat head and spine trauma, sports injuries, degenerative diseases, infections, tumors, and congenital conditions. Various retraction tools and instruments are employed by these surgeons, and procedures often also include the implant of plates, screws, pins, or other stabilizing products.

Orthopedic (also spelled orthopedics) Instruments and Implants are used in medical-surgical procedures concerned with conditions involving the musculoskeletal system, to treat trauma, sports injuries, degenerative diseases, infections, tumors, and congenital conditions. Procedures often include the implant of artificial joints, plates, screws, pins, or other stabilizing products.
Pipeline Integrity Tools are highly engineered instruments used to identify anomalies of every type and size in pipelines of all kinds. The information they gather helps operators and service teams to identify situations of metal loss, cracking, or location of a defect that may require repair or improvement.
