Two Machining Methods Of Beryllium Copper Tube

Beryllium copper tube is generally used as a large-scale mechanical bushing, and its main feature is high hardness and wear resistance. The quality of beryllium copper tube has a great relationship with the processing technology and process. There are generally two methods for processing beryllium copper tubes: one is direct casting and extrusion, and the other is hollowing out the base of the round bar. The former is obviously efficient, but the quality is poor, the latter is obviously inefficient, but the quality is absolutely good. Why is there such a clear difference? The main reason is that the density, hardness, conductivity, pores, sand holes and other properties of the Read more

The Machining Characteristics Of Beryllium Copper

The aging temperature of beryllium copper is related to the content of Be, and alloys containing less than 2% of Be are suitable for aging treatment. For alloys with Be greater than 7%, the aging temperature is 301-331 °C, and the holding time is 1-3 hours (depending on the shape and thickness of the part. For high conductivity electrode alloys with Be less than 0.5%, due to the increase in melting point , the aging temperature is 450-481 ℃, and the holding time is 1-3 hours. Corrosion depth (9-1×10-3 mm/year. After corrosion, there is no change in compressive strength and tensile strength, so it can be maintained in the sea Read more

Beryllium Bronze Material Machining And Selection Of Cutting Fluid

Beryllium bronze material, as a metal material with good comprehensive properties, has been widely used in the field of petroleum logging. Its high strength, high hardness and other characteristics make it easy to generate large cutting force and high cutting force during Beryllium Machining. The temperature will increase the wear of the tool. Therefore, we must combine the cutting characteristics of C17200 beryllium copper material to select reasonable cutting tools, tool geometric parameters, cutting amount and cutting fluid. At the same time, we need to arrange according to the actual situation in production Reasonable processing technology. During beryllium cnc machining, attention should be paid to production safety and product quality Read more

The Application Field Of Beryllium

As a new material, beryllium has been paid more and more attention, and beryllium is an indispensable and valuable material in atomic energy, rocket, missile, aviation, aerospace and metallurgical industry. Among all metals, beryllium has the strongest ability to transmit X-rays, and is called metallic glass, so beryllium is an irreplaceable material for making small windows of X-ray tubes. Beryllium is the treasure of atomic energy industry. In atomic reactors, beryllium is a neutron source that can provide a large number of neutron shells (hundreds of thousands of neutrons can be generated per second); beryllium has a strong deceleration effect on fast neutrons, which can make the fission reaction continue.

The Properties Comparison Of Beryllium Aluminum

In the periodic table, beryllium is in a diagonal position with aluminum in group IIIA, and their properties are very similar. The standard electrode potentials are similar: they are all active metals. They are all oxygen-loving elements, and the metal surface is easy to form an oxide protective film, which can be passivated by concentrated HNO₃. Both are amphoteric metals. Hydroxides are also amphoteric. Both BeO and Al2O3 oxides have high melting points and high hardness. Both BeCl2 and AlCl3 are electron-deficient covalent compounds that form polymeric molecules through bridging bonds. Beryllium salts and aluminum salts are easy to be hydrolyzed, and the hydrolysis is acidic. Beryllium carbide Be2C, like Read more

The Classification Of Beryllium Element

Beryllium, like lithium, forms a protective oxide layer in the air, so it is stable even when it is red hot in the air. Insoluble in cold water, slightly soluble in hot water, soluble in dilute hydrochloric acid, dilute sulfuric acid and potassium hydroxide solution to release hydrogen. Metal beryllium has significant corrosion resistance to oxygen-free sodium metal even at higher temperatures. Beryllium is in the +2 valence state and can form polymers as well as a class of covalent compounds with significant thermal stability. Anomalous Properties Of Beryllium The valence electron shell structure of Be atom is 2s2, its atomic radius is 89pm, the Be2+ ionic radius is 31pm, Read more

The Effect Of Beryllium On Human Health

Beryllium Poison And Industrial Hygiene Beryllium and its compounds are toxic to the human body and are one of the most toxic elements. Industrial hygiene and environmental protection of beryllium operations must meet safety standards. Beryllium Poisoning Recognition Process In 1933, Germany first reported the poisoning of workers exposed to beryllium compounds, and in 1942, it was reported that workers exposed to beryllium silicate and beryllium hydroxide were poisoned by beryllium. The United States first put forward the report of beryllium poisoning in 1943, and implemented the occupational beryllium poisoning patient registration system in 1951. By the end of 1977, 887 cases had been registered. Western countries have also reported Read more
