Aluminum alloy coated aluminum division successfully trial-produced 319Z.3 cast aluminum alloy products

SMM News: in order to actively meet the market demand and enhance the strategic deployment of product differentiation, the aluminum alloy business department, combined with the reality of the market and equipment, continues to develop new products and actively practice the new mission of "updating alloys for a lighter and greener world". This year, the mechanical properties of ALSi10Mg, A356, 702A and other alloy products have been improved successively. On the basis of summarizing the production process and technology, AlSiCu series high-strength 319Z.3 aluminum alloy products for pistons have been trial-produced with phased success, filling in the blank of high-Cu aluminum alloy products and laying the foundation for the development of multi-component high-end alloy products.

As customers have high requirements for pinholes of 319Z.3 alloy products, and it is extremely difficult to control them in the casting process, since receiving the market order, the professional and technical staff of the alloy division have repeatedly demonstrated the feasibility of trial production equipment and process, and worked out a detailed trial production plan in early November, after multi-party discussion and revision, to ensure the success of ALSiCu trial production at one time.

During the trial production, the production technicians follow up and guide the production throughout the process and record the process parameters. The low power pinholes of the three heats of products are all above the second grade, which fills the blank of low magnification and low pinhole of high Cu alloy products.

Based on high-quality development, the alloy business department takes the development of new products as an opportunity to transform and upgrade the structure of alloy products. In the later stage, we will continue to carry out the research on the use of the first batch of products, improve the operation instructions and implement the follow-up production.
