Problems solved by technology

[0002] At present, the solder bars used in the market are generally made of tin-lead alloy. The tin-lead alloy has many deficiencies during use, such as being easily extinguished during combustion, which affects the work. In addition, the ignition point is high and it is inconvenient to use. , In addition, due to the presence of lead, harmful substances containing lead will be produced during the combustion process, polluting the environment
[0003] In view of this, some researchers researched and explored the formulation of the above materials, and used tin, aluminum, magnesium, zinc, sodium, potassium, and carbon as raw materials to prepare them, so as to avoid the pollution of lead to the environment and avoid flame extinguishing; but , due to its high carbon content, it is prone to bursting when it is burned, causing waste, and it is not safe
[0004] In addition, the application of aluminum alloy is mainly used in aerospace and other macroscopic equipment, and there is no relevant technical literature on the preparation of aluminum alloy electrodes. Based on this, this researcher applies aluminum alloy to the field of electrode preparation to prepare an aluminum alloy Composite SnPt metal material

Abstract

The invention relates to the technical field of aluminum alloy composites, particularly to an aluminum alloy material compounded with tin and platinum metals and a preparation method of the material. After elements of platinum, sodium, silicon, magnesium, potassium, titanium and the like are added into a formula, the inflammability of the obtained aluminum alloy material compounded with tin and platinum metals is greatly enhanced, at the same time, the ignition point is also lowered, and the safety is improved; moreover, burning of heavy metals and radioactive elements cannot be generated, so that cleanliness and environmental protection are achieved; in addition, the component of carbon in the formula is removed and replaced with silicon, so that the extrusion difficulty is reduced, the flexibility of the material is improved, an explosicum phenomenon caused during burning is avoided as well, and waste is avoided.
