A metal alloy made of cobalt and chromium is known as cobalt-chromium (CoCr). Cobalt-chromium powders have been shown by scientists to be resistant to oxidation and corrosive gasses, and they showed no outward signs of tarnish even after being exposed to boiling nitric acid.
Recently, Co-Cr alloy powder has been utilized to make numerous artificial joints, such as hips and knees, dental partial bridge work, gas turbines, and many others because of its great resistance qualities, biocompatibility, high melting points, and extraordinary strength at high temperatures.
Co-Cr alloy powders exhibit remarkable corrosion resistance as a result of the spontaneous development of a protective passive coating made primarily of Cr2O3.
The global cobalt chromium powder market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
Wallex Cobalt Chromium powders and discs are introduced by Wall Colmonoy for AM dental applications. For the dentistry sector, Wall Colmonoy Limited, Pontardawe, Wales, UK, has introduced a new line of Wallex Cobalt Chromium powders and cast discs.
Due to its biocompatibility, robustness, and wear resistance, Wallex Cobalt Chromium powders for additive manufacturing are reportedly perfect for dental implants, partial dentures, and prosthetics.
CoCrMo, CoCrW, and CoCrMoW are the three major chemistries of cobalt chromium powders offered by Wallex. The powders are reportedly produced in a special alloy processing cell at Wall Colmonoy’s UK facility and have exceptional flowability and are completely spherical.According to the business, the powders are distinguished by their high particle density, lack of nickel, and extremely low oxide concentration.
The nickel-chromium-cobalt superalloy Amperprint 0233 spherical powder from KBM Advanced Materials is gamma-prime strengthened for use in high temperature applications. Up to 930°C, it exhibits a fair balance of creep strength. To make Amperprint 0233 one of the strongest powders on the market, it underwent a number of processes.
This nickel superalloy was created by vacuum induction melting, argon gas atomization, and gamma-prime strengthening. It has a wide range of applications.
Within the business division of Sandvik Materials Technology, the company will invest in a new factory for the production of titanium and nickel fine metal powders.
The investment will bolster Sandvik’s position in the quickly expanding markets for metal powder and metal additive manufacturing. It will complement the company’s current powder offering.
Today, Sandvik is the market leader in the creation and distribution of fine metal powders. In Sweden and the UK, alloys based on nickel, cobalt, and stainless steel are produced. Through the Osprey brand, sales are made throughout Europe, North America, and Asia. In the upcoming years, there will likely be a major growth in the need for metal powder for additive manufacturing.
Cobalt Chrome Superalloy, a novel 3D printing substance, has been introduced by Protolabs, a leader in digital prototyping. The UK-based business predicts that the heat-, wear-, and corrosion-resistant material will upend a variety of sectors, notably the oil and gas sector, where tailored cobalt chrome parts were previously unattainable.
“Cobalt Chromium Powder is one of the strongest materials known and can be polished to an extraordinarily smooth surface. The benefit of 3D printing is that it allows us to create any shape we want, whether it’s for odd geometry or to reduce weight.
High corrosion resistance and great biocompatibility make cobalt chrome a popular choice for use in the medical and dentistry industries. Due to its creep resistance, it can function in temperatures of up to 600 C. Additionally, due to its excellent strength-to-weight ratio, it is a great choice for aerospace applications.
The novel substance will be utilized in Protolabs’ direct metal laser sintering procedure, which uses a high-power laser to melt metal alloy powder and bond it into solid layers. Once a 3D shape has been created, the layers are once again powder-coated. The generated parts have an incredibly fine resolution, with millimeter-level feature sizes and wall thicknesses.
Protolabs calls itself the “fastest digital manufacturing company in the world” and claims to be able to build complicated parts in as little as a day using the method.
Due to its great wear resistance, cobalt chromium powder is actually quite difficult to CNC machines. Additionally, when utilizing subtractive manufacturing, the shape and structure of the pieces tend to be constrained. The new cobalt chrome powder may be the best option for businesses wishing to quickly prototype and test a new product for both form and function.
“The production process is quick; after submitting the design into our Protoquotes program, you’ll normally receive a quote back in a couple of hours. The part can be created for shipping in as little as a day after being approved. You can drastically reduce your product development and lead times when you compare this to the numerous days or even weeks that other vendors have stated.
