Recently, covid 19 outbreak spreads in Shanghai, China. There are more than 25,000 new asymptomatic domestic infections every day. China is implementing a dynamic zero-out policy. A leading respiratory expert said the key to COVID-19 prevention and control is to minimize transmission and fatality rate. Omicron has a low case fatality rate but is highly transmissible and can still claim many lives in large outbreaks. "Total openness is not applicable in China. For China, we should keep to the dynamic zero-out and gradually open up."
However, "dynamic zero clearance" is not the pursuit of complete "zero infection". As the Novel Coronavirus has its own uniqueness and strong concealment, there may be no way to prevent the detection of cases at present, but rapid detection and prompt treatment must be carried out, as soon as one case is found, one case will be dealt with.
The situation in Shanghai is serious. As the financial center of China, Shanghai is a very important city, and the outbreak of the epidemic in Shanghai will put a great impact on China's economy. The current task is to contain the spread of the epidemic as soon as possible, to achieve social zero so that Shanghai's life and economy quickly return to normal.
As China plays an important role in the global supply chain, the outbreak will have a significant impact on the supply and prices of many Cobalt Chromium Molybdenum.
About 3D Metal Printing Cobalt Chromium Molybdenum CoCrMo Powder:
CoCrMo alloy (CoCrMo) is a kind of cobalt base alloy, is also commonly known as Stellite (Stellite) alloy, is a kind of wear resistance and corrosion resistance of cobalt base alloy.The original cobalt base alloy is a cobalt chromium binary alloy, later developed into a cobalt chromium tungsten ternary composition, and then later the development of cobalt chromium molybdenum alloy.Cobalt-chromium-molybdenum alloys are alloys with cobalt as the main component and contain a considerable amount of chromium, molybdenum, and a small amount of nickel, carbon, and occasionally iron. Cobalt and chromium are two basic elements of cobalt-based alloys while adding molybdenum can produce finer grains and higher strength after casting or forging.Cobalt-chrome-molybdenum alloys are basically divided into two categories: CoCrMo alloy and ConicrMo alloy;
1. The first category is CoCrMo alloys, usually cast products; The improvement of the technology greatly improves the comprehensive mechanical properties of the material.
2. The other type is ConicrMo alloys, which are usually (hot) forged and precision machined. Cast CoCrMo alloys have been used in dentistry for decades and are currently used to make artificial joints, while forged ConicrMo alloys are used to make heavy joints that can withstand heavy loads such as knees and hips.

Research and development of selected laser melting equipment, such as Huaying Hi-Tech, Platinum and so on.
How is 3D Metal Printing Cobalt Chromium Molybdenum CoCrMo Powder Produced?
Water atomization method, it is the use of medium frequency induction furnace melting materials alloy, the melt leakage by only a few millimeters in diameter eye forming metal liquid column, in the process of falling by more than surrounded by high-pressure water metal liquid column, a shock to turn it into a metal powder, and then again through the water, powder separation device, will collect the wet powder dry can. Using radiofrequency (rf) plasma spheroidization system for water atomized powder was prepared by the irregular cobalt chromium molybdenum alloy powder for further processing, after a series of processes such as plasma zone melting solidification, ultimately morphology rules (≧ 90%), high rate, high sphericity and good performance of high packing density, micron grade spherical cobalt chromium molybdenum alloy powder.
Applications of 3D Metal Printing Cobalt Chromium Molybdenum CoCrMo Powder :
Depending on the composition of the alloy, CoCrMo alloy can be made into welding wire, powder for hard surfacing, thermal spraying, spray welding and other processes, but also can be made into casting and forging parts and powder metallurgy parts.
CoCrMo alloys are particularly susceptible to work hardening and therefore cannot be manufactured in the same way as other metals, requiring vacuum precision casting instead. Controlling the mold temperature can control the grain size of the casting. The formation of coarse grains at higher temperatures will reduce the strength, but it will also precipitate large and far apart carbides and reduce the brittleness of the material.
CoNiCrMo alloy is one of the promising forging cobalt-base alloy, originally called MP35N, when under stress, can be in the water of the sea (containing chloride ions) has high corrosion resistance, cold working can increase the strength of the alloy, but cold work have considerable difficulty, especially in manufacturing large devices, such as hip handle, only hot forging was suitable.
CoNiCrMo alloy wear-resistant properties of forging and casting CoCrMo alloy has good fatigue resistance and the advantage of high tensile strength, so it is suitable for application in long life and do not need or stress fatigue fracture, hip place of artificial joints, for example, for the implant is deeply embedded in the femoral bone marrow catheter this difficult and costly in terms of operation, This advantage is very important.
The elastic modulus of cobalt-based alloys does not change with the maximum tensile strength, which ranges from 220 to 234 GPa and is higher than that of other materials such as stainless steel.
CoCrMo alloy powder is mainly used for 3D printing of biomedical materials such as teeth, human scaffolds and artificial joints.

Cobalt Chromium Molybdenum Health & Safety Information
The World Food Program (WFP) of the United Nations (UN) and the European Union (EU) said in a statement that the conflict between Russia and Ukraine poses risks to global food supplies, and called on the international community to increase support for vulnerable countries and jointly address food security challenges.
A few days ago, the Executive director of the World Food Program, the European Commission's commissioner in charge of crisis management, the French Foreign Minister of the ROTATING EU presidency, and other officials held a meeting in Rome, Italy, to discuss how to deal with the negative impact of the Conflict between Russia and Ukraine on global food security.
One of the officials told a news conference after the meeting that the world was facing a food supply challenge that would "last for many years" as the conflict between Russia and Ukraine pushed up global food prices and disrupted the Cobalt Chromium Molybdenum will continue.
