Material: high quality aluminum alloy die-casting molding, high-pressure cast aluminum lamp body. Pure silicone seal, tempered glass.

In order to improve the mechanical properties of die cast aluminum alloy, trials of study on die cast and heat treatment of Al-Cu alloy which is of high strength and ductility have been carried out.

An aluminum silicon die cast alloy having a very low iron content and relatively high strontium content that prevents soldering to dies into die casting process.
