What are the commonly used mold aluminum plate?

Aluminum die with high precision, long life, easy to process, can be many characteristics, such as many times, is very popular in recent years, a variety of mold. In the aluminum plate series, for the mold manufacture mainly has the hardness of 5, 6 series of alloys and the hardness of 2, 7 series of alloys, enterprises can choose according to different needs.

2 aluminum plate belongs to Al Cu alloy, the main alloy element is copper. Copper is an important alloying element, has the solid solution strengthening effect, the aluminum alloy after the addition of copper, obviously enhanced, the alloy has a very obvious strengthening effect, the copper content in the 4%-6% effect is the best.

5 series aluminum sheet is aluminum magnesium alloy, in addition to have the mold manufacturing accident, aluminum magnesium alloy is the most commonly used in the automotive industry. Magnesium has a significant strengthening effect on aluminum alloy, and the tensile strength increased by 1% mg / Al in the alloy 34MPa. Aluminum magnesium alloy with moderate strength, strong plasticity, good welding and rust resistance.

The 6 series aluminum plate belongs to Al Mg Si alloy. The main alloying elements are magnesium and silicon elements. Add silicon in the alloy, can make Aluminum Alloy excellent casting performance and corrosion resistance of alloy elements, three kinds of aluminum magnesium silicon according to a certain proportion formed with excellent performance, is one of the main high-end manufacturing precision mold materials.

The 7 series aluminum plate belongs to Al Zn Mg alloy. The main alloying elements are zinc and magnesium. In the alloy adding zinc alloy elements on the strengthening effect is not obvious, and will bring stress corrosion cracking and other problems; but the two elements of zinc and magnesium to form AlZn2, has a strong effect on the alloy strengthening, yielding strength and tensile strength of the alloy increases with the proportion of the rise. 7 series aluminum plate is also an important material for aerospace industry.
