Embodiment Construction

[0018] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth in this specification; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will convey information to those skilled in the art. Fully express the concept of the present invention.

[0019] In an embodiment of the present invention, weight % (wt %) means the weight of a component expressed as a percentage in the total weight of the alloy. When the weight % range is greater than or lower than the boundary value, it can be understood that the boundary value is not included; and when it is indicated simply as a range or as equal to or greater than or equal to or less than, the boundary value is included.

Abstract

The present invention relates to a metal alloy, and more specifically, to an aluminum alloy used in electrical, electronic, mechanical parts and the like, and an aluminum alloy casting prepared by using the same. An aluminum alloy according the one embodiment comprises 4-13 wt% of silicon (Si), 1-5 wt% of copper (Cu); zinc (Zn) in an amount equal to or more than 26 wt% and less than 40 wt%; and the remaining aluminum (Al) and inevitable impurities.

Description

technical field [0001] The present invention relates to metal alloys, more particularly aluminum alloys for electrical, electronic and mechanical components, and aluminum alloy castings made using said aluminum alloys. Background technique [0002] Recently, as electronic products such as notebook computers and mobile phones have become more complex in appearance and function, there has been an increasing demand for high-strength materials that are more resistant to deformation. In particular, some components, such as brackets that support part of a liquid crystal display (LCD) panel and hinges that are thin and complex in shape, require lightweight materials for portability and high strength similar to stainless steel (such as 304 stainless steel) . However, although stainless steel can be formed by pressing or forging, stainless steel has limitations in mass production and realization of precise product shapes, and is heavier than stainless steel with a specific gravity o...
