Problems solved by technology

[0004] For example, in the field of automobile steering wheel manufacturing, the existing steering wheel mostly uses magnesium alloy as its material. Under the condition of the structural strength and toughness of the existing magnesium alloy, the existing steering wheel mostly adopts three or four-spoke structure, in order to realize the light weight of the steering wheel. Quantitative design requires a two-spoke design for the steering wheel, but this requires optimization of the existing magnesium alloy, so that the new magnesium alloy can achieve a better performance than the three-spoke steering wheel of the original material under the two-spoke structure. Higher strength and toughness, in addition, it can also solve the cost problem caused by severe oxidation and large burning loss of current magnesium alloys in the process of production and remelting

Description

technical field [0001] The invention belongs to the field of metal materials and relates to the field of magnesium-aluminum alloy preparation, in particular to an aluminum-magnesium alloy for casting a two-width steering wheel frame and a preparation method thereof. Background technique [0002] With the popularization of automobile technology, the family car market has opened up in a large number, and the competition among automobile manufacturers has become increasingly fierce. Lightweight design, as an effective method to improve fuel competitiveness, is the main research direction of most automobile manufacturers. [0003] In lightweight design, in addition to structural improvement, its essence also requires the participation of more new materials, so as to ensure its structural performance, reduce the self-weight of the corresponding structure, or cooperate with new structural design to replace the more bulky original structure. [0004] For example, in the field of a...
