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
