      硅對硬質合金有腐蝕作用。雖然一般將超過12%Si的鋁合金稱為高硅鋁合金,推薦使用金剛石刀具,但這不是絕對的,硅含量逐漸增多對刀具的破壞力也逐漸加大。因此有些廠商在硅含量超過8%時就推薦使用金剛石刀具。
      Silicon has a corrosive effect on cemented carbide. Although the aluminum alloy with more than 12% Si is generally called high silicon aluminum alloy, and diamond cutting tools are recommended, this is not absolute. With the gradual increase of silicon content, the destructive force of cutting tools is also gradually increased. Therefore, some manufacturers recommend using diamond tools when the silicon content exceeds 8%.
      硅含量在8%-12%之間的鋁合金是一個過渡區間,既可以使用普通硬質合金,也可以使用金剛石刀具。但使用硬質合金應使用經PVD(物理鍍層)方法、不含鋁元素的、膜層厚度較小的刀具。因為PVD方法和小的膜層厚度使刀具保持較鋒利的切削刃成為可能(否則為避免膜層在刃口處異常長大需要對刃口進行足夠的鈍化,切鋁合金就會不夠鋒利),而膜層材料含鋁可能使刀片膜層與工件材料發生親合作用而破壞膜層與刀具基體的結合。因為超硬鍍層多為鋁、氮、鈦三者的化合物,可能會因硬質合金基體隨膜層剝落時少量剝落造成崩刃。
      Aluminum alloy with silicon content between 8% - 12% is a transition zone. Both ordinary cemented carbide and diamond tools can be used. However, when using cemented carbide, tools with PVD (physical coating) method, no aluminum element and small film thickness shall be used. Because the PVD method and small film thickness make it possible for the tool to maintain a sharp cutting edge (otherwise, in order to avoid the abnormal growth of the film at the edge, the edge needs to be passivated enough, and the cutting aluminum alloy will not be sharp enough), and the aluminum content of the film material may cause the affinity between the blade film and the workpiece material and destroy the combination between the film and the tool matrix. Because the superhard coating is mostly a compound of aluminum, nitrogen and titanium, it may cause edge collapse due to a small amount of peeling off of cemented carbide matrix with the film.
      建議使用下列三類刀具之一:
      One of the following three types of tools is recommended:
      1.不鍍層的超細顆粒硬質合金刀具
      1. Uncoated ultra-fine particle cemented carbide tools
      2.帶未含鋁鍍層(PVD)方法的硬質合金刀具,如鍍TiN、TiC等
      2. Cemented carbide tools with non aluminized coating (PVD) method, such as tin plating, tic plating, etc
      3.用金剛石刀具
      3. Use diamond tools
      刀具的容屑空間要大,一般建議用2齒,前角、后角要大(如12°-14°,包括端齒后角)。
      The chip holding space of the tool should be large. Generally, it is recommended to use 2 teeth, and the front angle and rear angle should be large (such as 12 ° - 14 °, including the rear angle of the end teeth).
      如果只是一般銑面,可以用45°主偏角的可轉位面銑刀,配用專門加工鋁合金的刀片,應該效果更好。

      If it is only a general milling surface, the indexable surface milling cutter with 45 ° main deflection angle can be used, and the effect should be better when equipped with a blade specially processing aluminum alloy.
      氧化鋁在1808年在實驗室利用電解還成為鋁材,于1884年即被作為建筑材料使用在美國華盛頓紀念碑尖頂上至今;鋁材加入各種金屬元素合成的鋁合金材料已被建筑工業廣泛應用在各環節上。 鋁合金常用板材厚度:高級金屬屋面(和幕墻)系統的一般為0.8-1.2mm(而傳統的一般要≥2.5mm).
      Alumina was electrolyzed in the laboratory in 1808 and became aluminum material. It was used as a building material on the spire of the Washington Monument in 1884; Aluminum alloy materials synthesized by adding various metal elements have been widely used in various links in the construction industry. Thickness of commonly used aluminum alloy plate: the thickness of advanced metal roof (and curtain wall) system is generally 0.8-1.2mm (while the traditional is generally ≥ 2.5mm)
