Embodiment Construction

[0036] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0037] The aluminum foam proportioning in embodiment 1-5 is as follows:

[0038]

[0039]

[0040] The foaming process of embodiment 1-5 is as follows:

[0041] (1) Heat the tungsten to melt first, then slowly add lanthanum, stir while adding, continue stirring for 10 minutes after the addition, and then lower the temperature to 500°C to obtain a tungsten-lanthanum alloy;

[0042] (2) Heat the aluminum ingot to 550-700°C, then add calcium, titanium, magnesium, iron and zinc, stir while adding, and continue stirring for 10 minutes until all melted to obtain an aluminum master alloy;

[0043] (3) Put the tungsten-lanthanum alloy and the aluminum master alloy into the melting furnace together, heat and melt, and stir evenly to obtain a foamed ...

Abstract

The invention discloses a foamed aluminum sheet for automobiles, which is characterized in that it is made of the following components in percent by weight: calcium: 4-7%, tungsten: 0.40-1.0%, titanium: 0.05-0.3%, magnesium: 0.08-0.4%, lanthanum: 0.05-0.25%, iron: 0.3-0.5%, zinc: 0.15-0.2%, and the balance is aluminum and unavoidable impurities. The composition of the invention is relatively simple, changing the formula of traditional aluminum foam and adding tungsten-lanthanum alloy can improve the energy absorption capacity of aluminum foam, and at the same time change the traditional foaming process, improve the foaming effect of aluminum foam, and solve the problem of uneven foaming in the traditional way .

Description

technical field [0001] The invention relates to the technical field of aluminum foam, in particular to an aluminum foam plate for automobiles and a foaming process thereof. Background technique [0002] The continuous development of modern high-tech has made the problem of electromagnetic interference and electromagnetic compatibility caused by electromagnetic waves increasingly serious, which not only causes interference and damage to electronic instruments and equipment, affects their normal work, and seriously restricts the international competitiveness of my country's electronic products and equipment. It will pollute the environment and endanger human health; in addition, the leakage of electromagnetic waves will also endanger the security of national information security and military core secrets. In particular, the electromagnetic pulse weapon as a new concept weapon has achieved substantial breakthroughs, which can directly strike electronic equipment, power systems, ...
