To create a more durable and sleeker Galaxy S6 and S6 edge phones, Samsung Electronics is using high-strength aerospace-grade aluminium supplied by New York-based lightweight metals company Alcoa, according to Reuters.

Alcoa is supplying its 6013 Power Plate for the manufacturing of Galaxy S6 and S6 edge phones.  

Alcoa's Power Plates' high-strength comes from the heat treatment. Produced in South Korea, the plates measure only a few millimeters thick. 

Alcoa's aerospace-grade aluminium called 6013 Power Plate, is 70% stronger than standard aluminum, MarketWatch said.

The high-strength aerospace-grade aluminium producer says Samsung Galaxy S6 phones made from 6013 Alcoa Power Plate are now globally available.

Alcoa is moving away from costly traditional smelting and refining processes. The company is concentrating more on automotive and aerospace.

The executive vice president of Samsung Electronics' mobile communication business, DJ Koh said New York-based Alcoa's Power Plate is exactly what Samsung needed to create phones which are thinner, lighter, and stronger for the customers.

Less than months after Samsung Electronics launched its flagship phones, the sales figure have hit the 6 million mark by the end of April.

According to Counterpoint, Samsung Electronics could become the top selling phone surpassing Apple's iPhone 6 series if the researcher's prediction of 50 million sales is achieved by Samsung's flagship models by the end of this year.

In April, Samsung Electronics' flat-screen S6 edge sold more compared than the rest of Samsung Galaxy phones. Samsung Electronics S6 edge phones would have sold more if it weren't for the supply constraints, which the company has said will be resolved within the current quarter.

By the year 2016, almost 250 percent growth for smartphones with metal bodies is expected. The expectation will surely boost demand for aluminium further. Which would make Alcoa very excited as it will surely have more to do with regards to the mobile manufacturing business.
