Zinc-aluminum alloy material with high vibration absorbance and high tensile strength

Abstract

The invention discloses a zinc-aluminum alloy material with high vibration absorbance and high tensile strength, comprising the following materials in parts by weight: 30-50 parts of pure aluminum, 45-65 parts of zinc alloy and 3-8 parts of silicon. As a great amount of zinc alloy is added in the existing pure aluminum in the invention, the weight of the zinc-aluminum alloy can be increased; and the casting purpose can be achieved in special occasions; so that the product has the advantages of the casting, the weight of the alloy can be increased and the effect for reducing amplitude and absorbing vibration energy is achieved.

Description

technical field [0001] The invention relates to a zinc-aluminum alloy material, in particular to a zinc-aluminum alloy material with high shock absorption and high tensile strength. Background technique [0002] Aluminum alloy is a relatively young metal material, which only began to be used industrially in the early 20th century. During World War II, aluminum was mainly used in the manufacture of military aircraft. After the war, due to the sharp decrease in the demand for aluminum in the military industry, the aluminum industry began to develop civilian aluminum alloys, expanding its application scope from the aviation industry to the construction industry, container packaging industry, transportation industry, electric power and electronics industry, Various sectors of the national economy such as machinery manufacturing and petrochemicals are applied to people's daily lives. At present, aluminum is used in a large amount and in a wide range, second only to steel, and h...

Problems solved by technology

At the same time, the existing aluminum alloys used for casting all take the light weight route, but in some occasions, the wear resistance and shock resistance of light aluminum alloys cannot meet the needs of industry, production and life, such as power steering for automobiles The pump bracket is connected by two parts and used together. After being casted with cast aluminum alloy, it is easy to generate vibration during use due to its light weight, which will increase the noise of the whole vehicle. At the same time, the power steering pump bracket is protected. For pulling sports products, the casting alloy needs to have good wear resistance and tensile strength. If steel plate weldments are used, there will be problems of low production efficiency, poor precision and high manufacturing cost.
