硬质合金球 cemented carbide balls
硬质合金球及阀座是由难熔金属wc和胶结金属co或ni所构成的经高温烧结的合金材料。其合金具有硬度高、耐磨性能好。在常温下刚性好、没有明显的塑性变形,及较小的热膨胀系数,该产品尺寸稳定性好,加工精度高。wc-ni基合金具有良好的化学稳定性
,耐酸、碱腐蚀,从而提高了产品的使用寿命。由于硬质合金的上述特点,使其广泛应用于轴承行业的球类滚动体,流体密封用旋转球、泵阀芯、石油采掘机单向阀芯、阀座等众多军、民品高科技领域。我公司生产的硬质合金球及阀座主要销往美国、日本、欧盟等国家和地区。年销可达数十吨,近百种规格、上千万粒以上。可根据用户的特定需求,自行设计、生产不同成分、性能和使用要求的硬质合金球类产品。本公司宗旨:质量第一、信誉至上、广交朋友、竭诚为用户服务。
