What are the commonly alloy used <strong>
aluminum plate for moulds</strong>? In the
aluminium sheet series, the main alloys used in die manufacturing are 5-6 series alloys with medium hardness and 2-7 series alloys with strong hardness.<br><br>
Aluminum moulds have many characteristics, such as high accuracy, long service life, easy processing, multiple recycling and so on. They are very popular moulds in recent years.<br>
The <strong>2000 series
aluminum plate</strong> belongs to Al Cu alloy, and the main alloying element is copper. Copper is an important alloying element. It has solution strengthening effect. The aging property of
aluminium alloy increases obviously after adding copper. It has obvious strengthening effect on the alloy. The best strengthening effect is when the copper content is between 4% and 6%.<br>
The 5000 series
aluminium sheet belongs to aluminium-magnesium alloy. In addition to having an accident in die manufacturing, aluminium-magnesium alloy is also the most commonly used
aluminium sheet in automobile industry. Magnesium element has obvious strengthening effect on
aluminium alloy. The tensile strength of the alloy increases by 34 MPa with the increase of 1% magnesium. Al Mg alloy has moderate strength, strong plasticity, good weldability and rust resistance.<br>
The 6000 series
aluminum plate belongs to Al Mg Si alloy, and the main alloying elements are magnesium and silicon. 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.<br>
The 7000 series
aluminum plate belongs to Al Zn Mg alloy, and 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. The 7 series
aluminum plate is also an important material in the aerospace industry.<br>
Features of aluminum mould plate:<br>
1. High strength heat treatable alloy.<br>
2. Good mechanical properties.<br>
3. Good usability.<br>
4, easy to process, good wear resistance.<br>
5, corrosion resistance and good oxidation resistance.<br>
Aluminum plate for mold has the following characteristics:<br>
1, material uniformity: heat treatment at 300 DEG C for technical excellence, product thickness (diameter), strength and hardness remained the same;<br>
2, high surface accuracy, reduce material waste;<br>
3, good processing performance: the deviation of chemical composition, strength and hardness to minimize processing to eliminate the "knife" and "tipping" phenomenon;<br>
4, high speed machining, almost no deformation: perfect pre stretching (T651) process, eliminate the internal stress in the processing and the force is not easy to warp, crack and deformation;<br>
5 material, good compactness: to ensure the grain refinement process unique, no sand hole, stripes, bubbles and impurities.</p>
