Novel high-performance aluminum alloy material and preparation method thereof

Abstract

The invention discloses a novel high-performance aluminum alloy material. The novel high-performance aluminum alloy material comprises the following components in percentage by weight: 16.0-18.0% of Si, 0.60-1.0% of Fe, 4.0-5.0% of Cu, 0.65-0.85% of Mg, less than or equal to 0.50% of Mn, less than or equal to 0.098% of Cr, less than or equal to 0.09% of Ni, less than or equal to 1.4% of Zn, less than or equal to 0.09% of Ti, less than or equal to 0.095% of Pb, less than or equal to 0.09% of Sn, less than or equal to 0.006% of Ca, greater than or equal to 0.0075% of P and the balance of Al andunavoidable impurities. The process is fine and reasonable in planning, high in stability and operability and large in adjustment range; the prepared alloy grains are homogenized and are high in quality and excellent in granularity and metamorphism; the prepared aluminum alloys are low in expansion coefficient and high in wear resistance and mechanical strength; through the advantages of wide crystallization range and large adjustment range of the process, the process is capable of rapidly converting the specifications of aluminum liquid for rush orders and ensuring the requirements of the consumers.

Description

Technical field [0001] The invention relates to an aluminum alloy, in particular to a novel high-performance aluminum alloy material and a preparation method thereof. Background technique [0002] With the increasing use of aluminum alloy materials, the types of aluminum alloys continue to increase. Nowadays, there are many types of aluminum alloy materials. The production of aluminum alloy ingots / cast aluminum is secondary smelting, and recycled aluminum products are used as raw materials. Such as: scrap automotive aluminum products, aluminum products for daily life, leftover materials from other aluminum processing, and reclaimed materials from die-casting plants, etc., after being smelted, they are turned into treasures and reused. [0003] In the aluminum ingot / cast aluminum production process, the ideal state is that the raw materials used are similar to the composition specifications of the production specifications of the aluminum liquid. This can reduce the operation of the...

AI Technical Summary

Problems solved by technology

Due to the large fluctuations in the price of aluminum scrap in the market and the instability of the amount of scrap aluminum / recycled aluminum, the specifications and quantities of raw materials are different in each stage, and there is a gap between the inventory of raw materials and the actual demand for raw materials. Only good ones can be used. The addition of raw materials or pure aluminum ingots causes waste of cost and resources
