1100 aluminum strip/coil for fin stock
Aluminum strips for heat exchangers can be readily brazed and combine light weight and strength with good workability. The material's resistance to corrosion, its ability to conduct heat and the fact that it is easily recycled are also key strengths in this application.
Signi aluminum manufactures and supplies aluminum finstock that meets the requirements of high quality heat transfer for automotive and housing applications.
Meeting the constantly evolving needs of users and customers is a priority for signi aluminum. The company's investment in research and development seeks to optimize the performance of our foil products as well as our manufacturing processes.
Fin stock |
By meeting stringent specifications of globally competitive companies, Signi's flat fin stock has proved its worth in air conditioners, car radiators and heat exchangers. With the help of high-quality ingots, state-of-the-art gauge and shape control and precision slitting, we manufacture finstock that has tight gauge tolerances and excellent slit edges. A tight build-up combined with internal sound metallurgical properties produce good drawability required for all types of finning. |

Packing |
Signi's flat finstock is packed on wooden skids in either eye-to-sky or eye-to-wall condition, wrapped in HDPE fabric and hardboard and strapped with hoop iron. Moisture protection is ensured with silica gel packets and as the final step, the entire packed product is placed in a wooden cage. |
