五金沖壓件常用原材料的代號說明


  SPCC:(冷軋碳鋼薄板)這種材料可分爲單光與雙光兩種料。此種料非常容易刮傷和生銹。在搬運時要戴手套,如果是長時間存放或下料之后必需涂防銹油,防材料生銹及劃傷。
  用途:家電商品,電腦機殼以及一些門板與面板,上海寶鋼可以消費,但鋅層質量較國外差很多。
  SECC:(電解亞鉛鍍鋅鋼板)因為此材料的產地很多,大概分為:
  1.臺灣;2.日本;3.韓國制造,因為種類比較多,在選擇材料的時候我們需要注意,耐指紋,具有很優越的耐蝕性,而且堅持了冷軋板的加工性。
  SGCC:(熱浸鍍鋅薄鋼板)臺灣料號為GI料,外觀分有花紋和無花紋兩種。國際尚無鋼廠能消費出優質的材料,主要從國外出口的。
  主要的特性:1、耐蝕性;2、上漆性;3、成形性;4、點焊性。
  用途:極爲普遍,小家電商品,表面好的地方,但比SECC相比,其價錢貴一些,很多廠家爲節省本錢均改用SECC。
  分類鋅花分:normalregular spangle和minimized spangle。
  沖壓模具設計:常見沖壓材料代號與名稱歸納,工程師人手一份。
  SPHC:(熱軋鋼板)一般稱爲熱軋板或黑鐵板,此種材料硬度大,主要用于簡單工序模具的制造。
  SPTE:(鍍錫板,俗稱馬口鐵)此種材料極易生銹、易刮傷。
  SGLD:(鍍鋁鋅鋼板)是一種包括富鋁及富鋅的多相合金材料。由于鋁和鋅的特性,使得它比SGCC的有更優異的性能。
  主要特性:1、耐蝕性,其才干比SGCC高出很多;2、耐熱性;3、熱傳導及熱反射性;4、成型性;5、焊接性。
  用途:用在一些要求反射性好的地方,如烤箱內部的反射板,電鍋的反射板。
  SK:(碳素工具鋼)常用SK材有SK-3,SK-5,SK-7三種。
  AL:(鋁)易刮傷、壓傷。常見的型號有1050、5020。此種材料有紋路,折曲時易斷。
  CU:(銅)有青銅、磷青銅、黃銅、紅銅(激光切割最難)。
  SUS:市面有301,302,304,430等。301彈性較好,較硬,無磁性,有紋路。一般下料切割時需旋轉45度,以免在折曲時斷裂。304彈性較差,較軟,無磁性,無紋路。430有磁性。
  顏色區分:
  SPCC看上去很暗,-SB這種很亮所以叫金光板。
  SGCC我見過大部分是亮的,小鋅花,其實很棒看出鋅花吧,大鋅花很明顯的可以看到那種六邊形的花塊。
  SGLC顏色上與SGCC差不多,但很顯地有小的花斑,很棒看的。
  SALD我見過與SGCC差多,但是覺得它要更亮些,有時很難區分的。
  沖壓模具設計:常見沖壓材料代號與名稱歸納,工程師人手一份。
  SECC是這些中最容易區分的,它是那種灰色與以上四種均不同很容易區分。
  SECC和SGCC,臺灣地區叫EG,GI料。EG經過電鍍構成鋅層,GI是把鋼板浸到融鋅經成鋅層。因此,EG比GI的鍍鋅效果好的多,加工成型性也好。鋅花的大小和鋅層厚度能說明鍍鋅質量的好壞,越小(到ZEROSPANGLE)越厚越好。當然,別忘了讓廠家加耐指紋處置。
