Compared with other materials, aluminum alloy molds have significant advantages such as light weight, good machinability, high temperature resistance, and good wear resistance.  
Aluminum plate for molds requires aluminum plate is generally a high-strength heat-treatable alloy, need to have good mechanical properties, usability, and easy to process. According to the use of the mold and the characteristics of the aluminum plate also need to have corrosion resistance and oxidation resistance.  

Shanghai Aluminum Industry Co., Ltd. is the largest privately owned aluminum processing listed company in China, with an annual production capacity of 650,000 tons. Shanghai Aluminum produces alloy aluminum plate grades for mold manufacturing, such as 6061, 6082, 5052, 5083, 7075, 7475, 7050, etc., which have good forming and processing performance. 

6061 aluminum plate is widely used in mold manufacturing, can be used for injection molds, blow molds, low-pressure molds, rubber molds and other different mold industry 80% of the products, so it is also known as the mold aluminum plate.  

6061 mold aluminum plate is generally used in 6 series of thick aluminum, Shanghai Aluminum produces 6061 mold aluminum plate, the thickest can be 600mm, the width of up to 3000mm, to meet the needs of a variety of different mold industry.  

6082 aluminum plate O and T4 state is suitable for bending and forming occasions, its T5 and T6 state is suitable for good machinability requirements of the mold, the general mold using 6082 aluminum plate is a medium-thick aluminum plate, some specific processing needs to use chip separator or other special process to help separate chips, widely used in machinery parts, forgings, commercial vehicles, railroad structures, shipbuilding and so on.  

The 1+1 hot rolling line of Shanghai Aluminum's "High Precision Aluminum Sheet and Strip for Transportation Project" was officially put into operation in July 2015, which is the widest hot rolling line in Shanghai. The main business of "1+1" is ultra-wide and ultra-thick aluminum plates and medium-thick plates, which will mainly meet part of the domestic market demand for aluminum plates for automobile molds, realizing Shanghai Aluminum's high-end leap from general public aluminum to automobile aluminum plates and rail aluminum.
