All knee replacements, partial or total, will have parts made of a few different materials (likely metals and plastic). In most cases, each component is built from titanium, cobalt-chromium alloys, or a titanium and cobalt mixed metal. Do they still use cobalt in knee replacements? Typically made from cobalt-chromium as Read more…
What Are Dental Crowns Made Of? Metal crowns can be made from various alloys, including gold, platinum, cobalt-chromium and nickel-chromium. Do dental crowns interfere with MRI? Materials Matter for Dental Crown Crowns made of porcelain, composite resin, or gold pose no risks from MRI. If a patient has a crown Read more…
Cobalt is a naturally occurring element found in rocks, soil, water, plants, and animals. Is cobalt natural or synthetic? Natural abundance Cobalt is found in the minerals cobaltite, skutterudite and erythrite. Important ore deposits are found in DR Congo, Canada, Australia, Zambia and Brazil. Most cobalt is formed as a Read more…
Cobalt steel is a type of high-speed alloy steel used primarily for cutting tools. Why is cobalt used in steel? Cobalt increases the bonding strength in the steel matrix and changes the microstructure of the finer secondary carbides. Also the growth rate and coalescence rate of the carbides decreases. This Read more…
Cobalt and nickel belong to the d-block elements which are metals. Is cobalt considered a metal? Cobalt is a lustrous very hard silvery metal belonging to a group called the “transition metals”. It is one of only 3 ferromagnetic transition elements along with iron and nickel. Is nickel a metal Read more…
In dentistry, Co-Cr alloys are commonly used for the fabrication of metallic frameworks of removable partial dentures and recently have been used as metallic substructures for the fabrication of porcelain-fused-to-metal restorations and implant frameworks. What is cobalt-chromium used for? Cobalt-chrome or cobalt-chromium (CoCr) is a metal alloy of cobalt and Read more…
Cobalt is added to the stainless steel alloy (Iron and Carbon) during formation, enabling resharpening without losing the drill bit’s cutting quality. Cobalt drill bits are best used on tool steel, stainless steel, and other hard ferrous metals. What does cobalt do for steel? Cobalt increases the bonding strength in Read more…
Cobalt (Co) alloys have been used for over seven decades in a wide range of medical devices, including, but not limited to, hip and knee implants, surgical tools, and vascular stents, due to their favorable biocompatibility, durability, and mechanical properties. Why is cobalt used in medical implants? Cobalt-chrome (Co-Cr) is Read more…
The addition of 2–12 percent cobalt to tool steels enables them to be used more effectively on hard materials for which deep cuts and high speeds are required. Cobalt improves the wear resistance of many alloys. What effect does cobalt have on steel? When cobalt is added to steel, it Read more…
Today it is a metal found in many products ranging from aircraft engines to lithium-ion batteries, including those in electric vehicles. Currently, the largest use of cobalt is in portable consumer electronics like cell phones, laptop computers, and tablets, which are all powered by lithium-ion batteries. Which products use cobalt?
