The foamed aluminum material 2000 is the most representative metal material that can contribute to the weight reduction of the material, which is due to the characteristics of the aluminum material,

In particular, the aluminum material 2000 is excellent in tensile strength and wear resistance stiffness compared to synthetic resins or wood, as well as lightweight material,

A foaming agent is added to the base material 2010, which is an aluminum material, and is made of a foamed aluminum material that is foamed into the foaming cell 2020, and is widely used as an industrial material requiring weight reduction and tensile strength and wear resistance stiffness.

However, the foamed aluminum material 2000, the manufacturing cost is increased at a high price of the aluminum material itself,

Compared to synthetic resins or wood, tensile strength and wear resistance stiffness are strengthened, but tensile strength and wear resistance stiffness are lowered compared to other metal materials, which makes it difficult to use industrial materials requiring high rigidity.

In addition, by using an alloy material in which zinc or copper is added to the aluminum or foamed aluminum material to improve the above problems,

Although it is used as an industrial material for the purpose of strengthening the tensile strength and wear resistance stiffness of the aluminum or foamed aluminum material,

In addition, since the heat resistance of zinc is reduced to 400 to 420 degrees, it is difficult to use it as an industrial material requiring high heat resistance.

Copper has excellent heat resistance from 1050 to 1080 degrees, but the production cost is increased due to the high price of copper raw materials, and the workability is deteriorated because the weight of the alloy material using copper is not reduced to high weight and the transportation and handling are inconvenient.

The sound-absorbing function is also improved to provide an industrial alloy material and a method of manufacturing the same, which have enhanced rigidity and heat resistance of a structure that can be used as an interlayer noise material of a building or an interior or exterior material of a building. Let's solve the problem.

By the "industrial alloy material and its manufacturing method" of the structure of this invention, the said subject is solved.

Due to the heat resistance, tensile strength, wear resistance stiffness and heat resistance of the composition of the present invention, the industrial alloy material and the manufacturing method thereof;

Since the transmission noise absorbed into the foam cell becomes a vortex in the foam cell, the noise transmitted to the sound insulating substrate is minimized, and the sound absorption function is also proved to be excellent.

In addition, in the case of the sound absorbing material using the foamed aluminum material of the comparative example, the sound absorbing function can be used due to the structure of the foamed cell, but it has been found to have problems in that the wear resistance, the tensile strength stiffness and the heat resistance are deteriorated even though the thickness is 7.0 mm;

In particular, it was found that 7.0 mm thick compared to Examples 1, 2, and 3 of the present invention results in excessive work weight and an increase in raw material costs due to excessive weight by the thickness.
