SF-PK material

  • parameters

SF-PK material is a new type of material. It consists of steel plate, copper powder layer and PEEK+ filling material. Its main performance is embodied in PEEK material. It is a polymer, temperature resistant, wear resistant and corrosion resistant material. Especially in the case of water lubrication and less oil lubrication, the performance is even better. Since the wear layer of the surface PEEK has a thickness of 0.1 mm or more, the service life of the SF-1 material is significantly longer than that of the general SF-1 material. At present, the high-quality shock absorber guide portion, the tank, the rocket lifting portion and the machine tool sliding guide have been Used, it is a high performance product.
