At present, with the market demand, the use and requirements of beryllium bronze are also increasing. The materials widely used in the market are: C17200/C17530 is more, the domestic sheet metal uses more QBE0.6-2.5, and the domestic national standard QBE0. 6-2.5 Compared with hardness, it has better wear resistance and is generally used in casting molds, die-casting molds, and drawing mold materials. The main advantages of punches are: high strength, high hardness, and high conductivity. The difference between imported mold steel and domestic mold steel: Most of the imported beryllium copper currently used in China is Japan NGK, and the grade materials are mainly: C17200. It has the same composition Read more

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 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, 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

Friends who are engaged in metal materials are not unfamiliar with beryllium copper. Beryllium copper is also called beryllium bronze. This is a high-quality elastic, high-conductivity, high-wear-resistant, high-strength material. Elasticity, strength, wear resistance, non-magnetic, no impact sparks, good processability in solution treatment state, while maintaining the excellent electrical conductivity of copper-based alloys. Below, the beryllium copper forging factory briefly introduces the relevant knowledge of the process beryllium copper and the Japanese beryllium copper heat treatment process. The relevant person of the beryllium copper forging plant said that the relevant test results show that the quenching of the Japanese material is wider than that of the domestic material, and the domestic Read more
