Delivery options by material and finish

  • The following materials and surface treatments are possible.
  • *Depending on shape and size, hanging holes may be necessary for surface treatment. Refer to the Design Guidelines for information on hanging holes.
  • *Steel between materials EN 1.1191 equiv and EN 1.1203 equiv may be used as an equivalent to EN 1.1206 equiv.
  • *EN 1.0038 equiv. (flat bar) and EN 1.1191 equiv. (flat bar) are not compatible with trivalent chromate.
  • *EN 1.0038 equiv. (annealed material) is not compatible with trivalent chromate (black) or hard chrome plating.
  • *The film thickness of hard chrome plating (flash plating) is less than 5μ. The hardness (Vickers) is about Hv750~, and it is difficult get the plating on holes and pockets.
  • *Hard chrome plating for International Economy products is a mixture of flash plating and non-flash plating.
  • *The value of EN 1.1206 equiv. (Reference Hardness: 20-34HRC) cannot be guaranteed and cannot be specified.
  • *Pre-hardened steel between 37 and 43 HRC may be used as an equivalent to NAK55.
  • *Black anodize (Matte) is not applicable for EN AW-6063 equiv. (flat bar).
  • *Thin plate standards (thickness 3㎜≤Z<5㎜)are not applicable for surface treatment.
  • *Not required for anodized aluminum if the displayed agreement is agreed to.
  • (However, a wire mark may be left)
  • *The thickness of Clear Hard Anodizing is approximately 10 to 30 μm. The color will vary depending on the thickness of the coating.
  • *Phosphating surface treatment will be either zinc phosphate or manganese phosphate. The type cannot be selected and the color and other characteristics vary for each.
  • *PPS (standard, natural color) does not contain glass fiber.
  • *Please click here for the hardness after heat treatment and here for quality assurance.
  • *The reference value for electrical resistivity for MC nylon (conductive) is 1-10² Ω・m and for MC nylon (antistatic) is 10⁴~10⁶ Ω・m.
  • *Matte treatments will have either a chemical or blasting pre-treatment. The type cannot be specified. (If the type needs to be specified, please request a manual quotation.)
  • ※Nitriding treatment will be either, gas nitriding or salt bath nitrocarburizing. The type cannot be specified. (If the type needs to be specified, please request a manual quotation.)
  • ※Please refer to the table below for the surface hardness after nitriding treatment. (Hardness is for reference only and is not covered by quality assurance)
