Benefits of technology

[0009]The present invention provides a continuous casting aluminum alloy for use as a high elastic continuous casting aluminum

Problems solved by technology

Disadvantageously, such high strength aluminum-copper (Al—Cu_alloys such as duralumin lack the ability to resist corrosion (i.e. they are prone to corrosion).
Recently, attempts have been made to generate a metal-based compound reinforced with carbon nanotubes (CNT) molded in a powder form, however, use of such a compound is limited because of its high cost.
Disadvantageously, when it was applied to a casting process in a powder form, major problems were encountered with dispersion of the powder in an Al matrix.
A further disadvantage results from a hypereutectic aluminum casing material that can only be made

Abstract

The present disclosure provides an aluminum (Al) alloy, for general casting, and a technique for producing the same. The Al alloy includes Al, Si in the range of 5 to 13 wt %, Ti in the range of 2 to 7 wt % and B in the range of 1 to 3 wt %. According to the disclosure, a TiB2 compound may be formed in the Al alloy, where the ratio of Ti:B may range from 2 to 2.5 wt %. The Al alloy of the disclosure has improved elasticity, and is suitable for general casting processes such as, for example, high pressure casting process.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims under 35 U.S.C. §119(a) the benefit of Korean Patent Application No. 10-2011-0125048 filed on Nov. 28, 2011, the entire contents of which are incorporated herein by reference.BACKGROUND[0002](a) Technical Field[0003]The present disclosure relates to an aluminum alloy as a casting aluminum material with high elasticity for improving the rigidity and noise, vibration, and harshness (NVH) characteristics, and a method for producing the same.[0004](b) Background Art[0005]Aluminum alloys improve the properties of aluminum and displays many excellent properties, which can be varied according to the composition of the alloy. For example, high strength aluminum alloys, such as duralumin, can be made by including copper, which provides high strength characteristics to the alloy. Increasing the copper content in the alloy has the effect of increasing the strength of the alloy. For example, super duralumin is created by adding...
