Embodiment 1

[0025] A commonly used lamp aluminum strip material, 1060 grade (GB), its composition mass percentage is: silicon 0.25%, iron 0.35%, copper 0.05%, manganese 0.03%, magnesium 0.03%, titanium 0.03%, single impurity 0.03%, the rest is aluminum.

Embodiment 2

[0027] A commonly used lamp aluminum strip material, 1060 grade (GB), its composition mass percentage is: silicon 0.15%, iron 0.2%, copper 0.03%, manganese 0.015%, magnesium 0.015%, titanium 0.03%, single impurity 0.02%, the rest is aluminum.

[0028] The preparation process of a new aluminum strip material for LED lamps as described in embodiment 1 and embodiment 2 comprises the following steps:

[0029] Proportion the melting furnace according to the content of the above metal elements. The melt temperature is 700~750°C. After the aluminum is melted, it is filled with nitrogen and degassed, and the covering agent is added to keep it for 20 minutes, and it is stirred evenly and slag is removed; the aluminum liquid meets the requirements. The refining temperature is 700~730℃, and the refining agent is still nitrogen. After refining, the liquid metal enters the pouring system (head box, liquid level control mechanism, feeding nozzle, etc.) through the launder. The liquid metal...

Abstract

The invention relates to a novel aluminum ribbon material for LED lamps. The novel aluminum ribbon material is prepared from less than or equal to 0.25% by mass of Si, less than or equal to 0.35% by mass of Fe, less than or equal to 0.05% by mass of Cu, less than or equal to 0.03% by mass of Mn, less than or equal to 0.03% by mass of Mg, less than or equal to 0.03% by mass of Ti, less than or equal to 0.03% by mass of a single impurity and the balance of Al. A preparation method of the novel aluminum ribbon material comprises smelting, casting, cold rolling, annealing, slitting, inspection, packaging and warehousing. Compared with the prior art, the preparation method reduces metal elements in the aluminum ribbon based on the mass percentage, improves aluminum residual, improves the plastic deformation of the metal and realizes stable mechanical and physical properties. The aluminum ribbon has high punch forming characteristics, prevents stamping and stretching cracking phenomenon of the heterogeneous complex products, effectively improves the production efficiency and has a low cost.

Description

technical field [0001] The invention relates to the technical field of aluminum strip materials, in particular to a new aluminum strip material for LED lamps. Background technique [0002] Aluminum is light in weight, forms a dense and solid oxide film in contact with air, and has anti-corrosion capabilities. It is suitable for long-term open-air climates exposed to wind, rain, and sun. The formation of oxide film on the surface of lamps plays a protective role, has a longer service life than ferrous metals, and is easy to process and shape. [0003] Aluminum strips are widely used in industry, and the lighting industry is one of them. With the development of technology, product innovation meets market demand. Commonly used materials, thickness 0.3 ~ 1.05 mm, pure aluminum 1060 brand after complete recrystallization annealed strip. [0004] At present, a kind of LED lighting material is different from the thickness increased by more than 1.2 mm. It still has good stamping...
