铍青铜是制作模具的理想材质之一。用它作为吹、注塑模,其使用性能甚佳,在400℃以下仍具有良好的强良、硬度、耐磨性以及抗热冲击性能、耐热疲劳和导热性能等。据资料介绍,美国把铍青铜应用于一些塑料制品的压注模,其使用寿命超过九百万次。铍青铜的导热性是钢的2—3倍,这样使每一次操作循环时间缩短40—50%,从而大大地提高了劳动生产率。它的另一优点是可铸性好,铍青铜的铸造性能是其它的类似模具材料远所不及的,对于皮革、木材等凹凸自然的纹理图案有极佳的复印性。铍青铜的耐腐蚀性也相当好,这对于塑料、橡胶中的某些化 Beryllium bronze is one of the ideal materials for making molds. Use it as blowing, injection mold, its performance is very good, below 400 ℃ still has good strength, hardness, abrasion resistance and thermal shock resistance, thermal fatigue and thermal conductivity and so on. According to the information, the United States used beryllium bronze in injection molding of some plastic products, and its service life exceeded 9 million times. The thermal conductivity of beryllium bronze is 2-3 times that of steel, thus shortening the operating cycle time by 40-50%, thus greatly improving labor productivity. Another advantage of this is its good castability. The casting properties of beryllium bronze are far behind those of other similar mold materials and provide excellent reproducibility of natural, textured textures such as leather and wood. Beryllium bronze corrosion resistance is also quite good, which for plastics, rubber in some of the
