Common Die Cast Aluminum Alloys. There are many aluminum alloys ideal for the die casting technique. However, an alloy must have certain features to make it a suitable candidate for aluminium die casting. These characteristics help engineers create aluminum die cast with great flexibility. Aluminum alloys for die casting. They include theLalu pada 1886, Charless Marrtin Hall seorang berkebangsaan Amerika Serikat (1863 – 1873) dan Paul L.T Héroult dari Prancis (1863 – 1914) menemukan proses elektrolisis yang sampai sekarang memproduksi aluminium ekonomis. Sejak saat itu aluminium diproduksi dalam jumlah banyak dengan harga yang cukup murah untuk memenuhi berbagai kebutuhan The production efficiency of die casting aluminum is high. For example, the domestic JIII3 horizontal cold air die casting aluminum machine can die-cast aluminium 600-700 times on average in 8 hours, and the small hot-chamber die casting aluminum machine can die-cast aluminum 3000-7000 times on average once every eight hours. The most common Zamak alloy is Zamak 3. Besides that, Zamak 2, Zamak 5, and Zamak 7 are also commercially used. These alloys are most commonly die cast. – Zamak 2: the composition is the same as that of Zamak 3, adding 3% copper in order to increase strength by 20%, which also increases the price. Zamak 2 has the highest tensile strength
The casting of aluminum alloys requires die steels with greater toughness and strength. Thus, die steels are more expensive and difficult to be machined. A typical die life used in aluminum die casting ranges from 100,000 to 150,000 castings. Increasing the number of parts to be cast from a single die may reduce the cost of the process.
The negatively charged O2- forms aluminum oxide, acting as the die cast aluminum surface finish. Anodizing is a simple yet cost-effective process. Hence, it is very popular in the automotive, food, and electrical industries. Depending on the electrolytic solution you use and the amount of current passed, there are different types of anodizing; 14 likes, 5 comments - ada_apa_diecast on October 21, 2020: ""Lelang Season 5" Part.144 20 Okt 2020 jam 23.00Wib OB : 25k NB : 3k (lebih boleh) BIN :40k " .
