硬質(zhì)合金球 Cemented Carbide Balls
硬質(zhì)合金球及閥座是由難熔金屬WC和膠結(jié)金屬Co或Ni所構(gòu)成的經(jīng)高溫?zé)�結(jié)的合金材料。其合金具有硬度高、耐磨性能好。在常溫下剛性好、沒有明顯的塑性變形，及較小的熱膨脹系數(shù)，該產(chǎn)品尺寸穩(wěn)定性好，加工精度高。WC-Ni基合金具有良好的化學(xué)穩(wěn)定性 ，耐酸、堿腐蝕，從而提高了產(chǎn)品的使用壽命。由于硬質(zhì)合金的上述特點(diǎn)，使其廣泛應(yīng)用于軸承行業(yè)的球類滾動體，流體密封用旋轉(zhuǎn)球、泵閥芯、石油采掘機(jī)單向閥芯、閥座等眾多軍、民品高科技領(lǐng)域。我公司生產(chǎn)的硬質(zhì)合金球及閥座主要銷往美國、日本、歐盟等國家和地區(qū)。年銷可達(dá)數(shù)十噸，近百種規(guī)格、上千萬粒以上�？筛鶕�(jù)用戶的特定需求，自行設(shè)計(jì)、生產(chǎn)不同成分、性能和使用要求的硬質(zhì)合金球類產(chǎn)品。本公司宗旨：質(zhì)量*、信譽(yù)至上、廣交朋友、竭誠為用戶服務(wù)。 This balls and valve seats are comprise of tungsten carbide(WC) and Co or Ni in high temperature sintering.With high hardness、better wear-resistant、high-temperature corrosion-resistant and maching properties of high working accuracy、high finish etc. Widely supplied ball-rolling element in bearing industry、pump valve spool for fluid seal、check valve for pretroleum digger etc.also used in high-tech area in army and civil.
