Problems solved by technology

However, for alloys that have not been modified, the primary Si exists in the form of plates, which severely splits the matrix and significantly reduces the mechanical properties; the combination between plates is weak, resulting in poor processability and loss of use. value
In addition to the long production cycle and high cost input, in order to maintain the inherent advantages of Al-Si alloy and greatly improve the mechanical properties, elongation and processing performance, the AlSi alloy must be improved and optimized to achieve good wear resistance, Low cost, high cost performance, to further meet the needs of customers, resulting in better economic and social benefits

Abstract

The invention discloses a hypereutectic aluminum alloy material. The hypereutectic aluminum alloy material comprises the following chemical components of, by weight, 3%-5% of Cu, 12%-14% of Si, 0-5% of Mn, 0.5%-0.65% of Mg, 0-0.1% of Ti, 0.5%-1% of Fe, 0-1.4% of Zn, 0-50 ppm of Na, 0-50 ppm of Ca, and the balance Al and inevitable impurities. According to the hypereutectic aluminum alloy material,the formula is scientific and reasonable, the cost is low, the cost performance is high, the strength is high, and the wear resistance is high.

Description

technical field [0001] The invention relates to aluminum alloy materials, in particular to a hypereutectic aluminum alloy material. Background technique [0002] In recent years, based on the requirements of lightweight automobiles, more and more automobile parts have gradually been replaced by light materials such as Al, magnesium, and plastics from steel and Fe. Among them, replacing steel and Fe with Al has become the main development direction of automobile lightweight. Due to the comprehensive consideration of cost, efficiency, performance, etc., more and more parts are currently formed by die casting, and the structure of the parts is becoming more and more complex. Or the eutectic Al-Si system (Yl102) alloy is developed to a special alloy material, such as the hypereutectic Al-Si-Cu system (ADC14, A390) is also gradually widely used in die-casting parts. Hypereutectic Al-Si-alloy has the characteristics of small thermal expansion coefficient, low density, good wear r...
