What are the Advantages of Spherical Tungsten Carbide Powder for 3D Printing
Wholesale gas prices in the Netherlands and the UK have risen 20 percent recently amid concerns about Russian supplies.
The EU plans to cut its dependence on Russian gas by two-thirds this year and stop importing Russian fossil fuels by 2027. Russia exported about 155 billion cubic meters of gas to the EU in 2021.
The US recently said it would try to supply 15bn cubic meters of LNG to the EU this year. U.S. LNG plants are running at full capacity, and analysts say much of the extra gas the U.S. sends to Europe comes from what should have been exported elsewhere.
The German government called Russia "an unreliable energy supplier". Even though the German government claimed that they have been preparing for the situation for a long time that Russia may stop sending gas one day, experts say it is hard for the EU to replace all of Russia's gas exports any time soon.
The supply and prices of many Spherical Tungsten Carbide Powder will continue to be influenced by international situations.
As a typical representative of refractory metal carbides, spherical tungsten
carbide powder is suitable for 3D printing and can produce higher quality
cemented carbide products.
3D printing, also known as additive manufacturing, is the latest rapid
prototyping device using technologies such as light curing and paper lamination.
The biggest difference from ordinary printers is that the printing material can
be liquid or solid powder. With the development of science and technology and
the needs of popularization and application, the use of rapid direct prototyping
to manufacture metal functional parts has become the main development direction
of rapid prototyping.
Compared with traditional production methods, additive manufacturing
technology has the characteristics of shorter production cycle, higher product
precision, and individualization. In addition to being suitable for the
manufacture of rapid prototyping small batch non-standard parts and
heterogeneous material assemblies, metal 3D printing is also suitable for
forming traditionally difficult parts, such as carbide tools, molds, structural
parts, geological mining tools, etc.
Cemented carbide is an alloy material produced by powder metallurgy with
tungsten carbide as the hard phase and cobalt, nickel, iron, copper and other
metal elements as the bonding phase. It has high melting point, high strength,
high hardness, good Red hardness, wear resistance, high temperature resistance
and other characteristics, so it is widely used in extreme environments such as
high temperature, high pressure, and high impact. However, alloys have very poor
machinability due to their high hardness and high melting point.
The researchers used 3D printing technology to manufacture cemented carbide,
which can effectively solve the problems of fracture, expansion and deformation
of products made by traditional production methods. However, additive
manufacturing technology has high requirements on the comprehensive performance
of raw materials, and spherical tungsten carbide powder must be used, because it
has the advantages of smooth surface, uniform particle size distribution, and
high fluidity, which is the premise of smooth powder feeding and uniform powder
distribution for 3D printers.

Inflationary pressures on Canadians continue to rise. The consumer-price index rose 6.7% in March from a year earlier, the biggest increase since January 1991, according to the latest figures from Statistics Canada.
On a month-on-month basis, Canada's CPI rose 1.4 percent in March, also accelerating from February's 1.0 percent rise.
Prices in the eight major sectors covered by the statistics continued to rise. The uptrend comes against the backdrop of continued price pressures in the Canadian housing market, widespread supply chain constraints, and geopolitical conflicts, according to CBC. A variety of factors have affected energy, commodity, and agricultural markets. Meanwhile, Canada's employment picture continued to improve in March, with the unemployment rate falling to a record low and the average hourly earnings of employees rising.
Excluding gasoline, Canada's CPI rose 5.5 percent year on year in March. It is also the highest since comparable data began in 1999.
The widespread supply chain constraints and geopolitical conflicts are expected to continue to affect the prices of the Spherical Tungsten Carbide Powder.
